Glare, Halos, and other Vision Problems - Multifocal IOLs & Opticians Upselling AntiGlare coatings

[@StudioCicada]

Your assessment about the single focal IOL being the safest bet for all contingencies is spot on. Thank you for your hard work in relaying this very important message for cataract sufferers about to undergo lens implant surgery. I received the Clareon Monofocal IOL a couple months ago--which replaced a very troublesome cataract. And the implanted monofocal lens is a dream come true. I still need reading glasses for computer work and reading (now just a +1.25 sphere for the operated-on eye). But for things like cooking, quickly scanning a menu, driving a night, and everything in the distance, I can see perfectly (20-20) now on the surgery eye. Sometimes less is more.

My eye surgeon really pushed and promoted the Panoptix IOL multi-focal lens on me. He did not inform me of the common problems associated with the multi-focal lens. The glares and halos are now much worse than when I had cataracts. Contrast sensitivity is now so bad that I can't read many labels in the grocery store, without my lighted magnifying glass. I still have difficulty seeing in low light areas. While reading, letters are often blurred and I must strain. My eyes are worse after cataract surgery than before surgery with glasses. I wish I had trusted my own logic and chosen the regular single vision lens implants and continued to wear my glasses. I do NOT recommend the multi-focal lens if you care about your overall quality of vision. I wish I had watched this video before my surgery.

I want to scream from the mountain tops to anyone considering getting multifocal IOL's like Symfony or the new one Panoptix. Please do a lot of research and consideration. Please read Jamie's comments below mine he has decided to have his swapped with standard mono. This is not a common procedure. You need to know your life at night is going to permanently change. Any kind of light outside at night is going to have a pronounced glare THAT DOESN'T GET BETTER. You just learn to live with it. It becomes your new normal. Headlights are the worst, imagine every headlight coming at you is a sparkler flaring out so far it touches the sparks coming off the other headlight, now times that by how many cars on the road coming your way. It's dark, so of course, there's going to be street lights MORE SPARKLERS! For me, all brake lights look like spider webs so now if you are following a car those are blending or bleeding into each other. Now imagine if it's raining, quite terrifying. Oh, and if you enjoy the moonlight (who doesn't) Remember I said "any kind of light" will have a glare. I was somebody who wore contact lenses for over 40 years I was extremely nearsighted my contacts box said -10. Simply put I was blind without them just about. My doctor actually wanted me to go with mono, My insurance would have paid 100%. Then I came across Dr. Shanon Wongs video's. He had just gotten a Symfony lens in one eye and couldn't stop praising it. (I'm not here to talk the Dr. down) But it honestly was his testimony that convinced me to pay $5000.00 out of pocket, the idea that I could have 20/20 and never having to deal with glasses or contacts again, no more dry irritated eyes, or the intense strain I went through when I took them out and had to wear glasses. I could swim with my eyes open, etc. So I financed the Symphony's a little over a year ago I was so excited. So by now, you're probably wondering if I regret it. For me...YES!!! Here's why. Every time I go out at night. OMG to have just one night without sparklers (Starburst) or spider webs. I cannot stress this enough it's life-changing. If I understand The Doctor here, Your eye functions best when the very back of your eye gets all the unimpeded light it can get. Thats what a Monofocal lens gives you naturally. As explained in this video the multifocal changes that. Unless you are a true homebody who doesn't enjoy going out at night, doesn't appreciate the moon, or counting the stars. Doesn't have to drive at night very often and just wants the freedom of not having to wear glasses for the most part. I would advise the Mono...or at least start with the first eye being mono.

[@stephenyoutubin4476]

I just had my right eye done with a acry sof IQ toric monofocal lense for astigmatism.My left eye is scheduled for Oct 12.It will just be a monofocal. My Doctor did not even offer these multifocal lenses.He removed the cataract from right eye and this lense is superior right away, clear and correct,I will need readers for super small text on lets say a pill bottle but thats it! I think they know it's a gamble with the multifocal lense and the track record is poor like your experience. My Hospital is Massachusetts eye and ear Infirmary so I have confidence in one of the best Hospitals in the Country. I hope you resolve your issue with that lousy Multifocal. Good luck.

[@auricgoldfinger8478]

Thank you so much for your testimony. I’m approaching surgery need, and will only consider mono focal lenses. The issue, unfortunately, is the incentive to bill more than insurance allows, which fosters physicians such as Wong to push alternatives that are profit centers.

Obviously there is always a trade off and as you say nothing is perfect, but I'm still pleased that I don't have to wear glasses anymore.

Ok, so I had my surgery today. Was thinking about toric because of my astigmatism. Heavily influenced by this video, I opted for monofocal lens. I just had left eye so far. It’s only hours after my surgery, and I’m seeing great! He said I will have to wear reading glasses. Of course he was pushing multi but I did my research on contrast sensitivity and compromised night vision. Btw I had coke bottle glasses so I’m pinching myself. Thanks Floater Doctor and fellow commenters! See you on the road...at night!

Oh. Great feedback. Thanks and congrats. I have naturally excellent distance vision. The glasses you see me wearing have no Rx for distance and just some power for up close. I don't mind it at all. I think if I had cataracts a multifocal lens 'may' have me out of glasses, but the optical quality 'uncertainties' and tradeoffs would be too great a sacrifice for me. I'll opt for a monofocal lens like you did. -Dr. J

Well done and congrats! From the video and the comments I got the same idea, the multifocal seems just like exchanging one discomfort for another one.

[@marycarla6245]

A great, straightforward, easy-to-understand presentation. You said many of the things my own cataract surgeon has said so I’m feeling even more comfortable moving forward with him now. I decided on monofocal for many of the reasons you said. Plus as a graphic designer my surgeon felt I’d be happier with the standard vision monofocal/toric (astigmatism) than an EDOF or multifocal. He did not try to upsell me. I felt the loss of contrast even if only at night would not be worth the extra foot or so of vision. I am now even more sure of my decision. Thank you.

I agree. Sounds like you have a very ethical surgeon.

[@hutchphotography]

30 days ago I did the cataract surgery and went with the Panoptix multi focal in each eye a week apart. 5K out of pocket. At this point, I do not need the contacts or glasses except for reading which is much clearer with the readers on. Can I read yes but strain so I wear readers still. Glare and halos are present as well as sensitivity to bright overcast skies more so than a sunny blue?? In addition occasionally a flicker or blinking sensation can come from the peripheral vision. I am 60 and wore daily wear contacts pretty much without issue for nearsightedness for 40 years. I will admit it was very emotional decision to get rid of all glasses and contacts and I did not do enough research prior to the surgery and that is on me. My hope is that with time my brain will adjust for some of the shortcomings I am experiencing. My sight is certainly not perfect and hindsight is of course 20/20 . . . but I would have waited till my vision was so bad with cataracts that I couldn't function and have no choice. Pre-surgery the cataracts in my left eye were pretty bad but the right eye was still fairly good. No turning back now but if anyone is considering this surgery at least they will know ahead of time that these are very real issues they could face. Perhaps what the eye surgeons should share more freely is the percentages of their patients with post operative issues like the ones which are mentioned in the comments here.

Wow. Unbelievably helpful, clear and objective. THANK YOU for the advice on lens.

Did they recommend mono vision for the next surgery? Of course not! Fortunately I saw your video, did a little more homework, and will now get monovision for the second surgery. I do have a fair amount of astigmatism, so I am wondering if the correction for that will cause any issues with glare, etc. I assume and hope not! Again, thank you so much.

Any updates? How is your vision ?

[@mortalstorm]

Thank you for such an excellent explanation of dysphotopsias as related to the insertion of a multifocal iol. My wife had cataract surgery with a monofocal lens insertion. Prior to the surgery the surgeon told her that the dysphotopsias she was experiencing due to the cataracts, would probably persist after the surgery. Sure enough the problems with night time glare, halos, etc., were still a problem after the monofocal lenses were inserted. Why would that be? Isn’t the monofocal lens just a clear optical device with no concentric rings that would otherwise scatter the incoming light on it’s way to the retina? May there perhaps be differences in the fabricating processes among different manufacturers that might cause the problems to persist post surgery? I read that some surgeons did in fact choose a particular manufacturer’s lens because of lessened “glistening” effects post surgery. With my upcoming surgery, I would like to explore all possible options to try and reduce the negative side effects of the procedure. I would be very grateful for any suggestions you might be able to provide.

[@Thefloaterdoctor1]

Thank you for your words of appreciation. I am only addressing the issues of multifocal lenses broadly and can not speak to recommend any particular lens as I no longer do cataract surgery myself. Re: your wife, I wonder if some topographical / wavefront measurements may reveal some irregular astigmatism of the cornea that might explain the problem.

I also have another question too... it seems like I prefer and it is more comfortable to end the day in my glasses vs using them in the beginning of the day? I am in my multi focal contacts the most of the day. I prefer it cause they don't hinder my view at all. I grew up in glasses and that is something I had always wanted was to be able to see the world without having stuff like glasses on. Now with all the extra bells and whistles blue light, anti glare, and now even the dimming into shades in the light they are more comfortable in a lot of ways.

My husband had mono focal, but is still having glare and halos.

[@MsAjax409]

Hi Dr. Johnson. What a wonderful presentation. You explain things so well. Regarding the choice of an IOL for cataract surgery, I passed on the multifocal IOLs due to dysphotopsias (halos, starbursts, etc) that interfere with night driving despite my wanting to be as glasses independent as possible. Monovision was an option, but after a trial period using contacts, I found monovision difficult to adjust to, and it negatively affected my depth perception. I chose to an extended depth of focus (EDOF) IOL for both eyes, offset by -0.5D, which increased my range of functional vision to 16 inches, I now have 20/20 distance vision and 20/32 close vision, and am thrilled to be nearly glasses free for the first time since I was a child. I achieved my goal of being able to use my smart phone without needing to put on glasses. Extending the depth of focus does reduce contrast sensitivity, however, but not enough to make night driving unsafe, but in low light conditions, I do need specs to read newsprint. I'm so happy to be able to apply eye makeup without a magnifying mirror. My lenses cost an extra $2500 out of pocket apiece, so that's a barrier to picking these lenses, but in the end, I personally think it was worth it. Unfortunately, the cataract surgery triggered PVD (posterior vitreous detachment) in my dominant eye with the formation of a Weiss ring that has greatly lowered the quality of vision in that eye and my ability to drive safely at night. The floater moves in and out of my line of sight so I doubt that neuro-adaptation is the answer. It's driving me crazy. I'm so glad to have discovered your channel. I'm hopeful that contrary to what I was told by my optometrist, YAG laser treatment offers the possibility of restoring the quality of vision that I paid so much to achieve, but then lost due to the sudden appearance of this large floater.

[@jyllirons167]

Hi. I had bilateral monofocal lens replacements 18 months ago. Left eye first, then right eye 2 months later. For few weeks after both surgeries I saw webs and strings of light at night when passing under overhead lights. This stopped when eyes settled down. One year ago the left eye had a complete PVD, which left me with huge floaters. A few months ago I developed a partial PVD in the right eye. I had some flashes and more floaters suddenly and saw the doctor at a local Moorfields eye unit. She said the incomplete PVD is pulling on the retina and the 'dip' you see on the scan is slightly raised. I am to be regularly monitored at the hospital. I was due to have FOV tomorrow ( left eye) , but the doctor scared me off of it and said it is very dangerous, so I cancelled. Typically my vision is good, except it is obliterated by floaters and my life is totally blighted. I cry about it every day and worry that I will end up blind. Well thats my story so far, but the question I have is this : why, more than a year after surgery, have the strings and webs of light suddenly returned, in both eyes, when I walk under streetlights/ overhead lights? Have my IOL's moved? This constant worry, and looking out for changes gives me panic attacks.

[@Thefloaterdoctor1]

Visual phenomenon can be broadly categorized as 'positive' or 'negative'. If you are seeing flashes of light in a darkened room, that is positive. If vision is diminished/missing/or a shadow is drifting across your vision, then that is 'negative'. If a poorly designed/place intraocular lens is refracting light with glare and halos, etc, that is also negative. A partial PVD will pull and tug on the retina yielding flashes of light. Those 'should' diminish over time and disappear when the vitreous membrane has completely detached. I am not sure what you mean by "strings and webs of light", but by clarifying as a positive or negative phenom., it may help sort out the culprit.

Thank you!! I have been reading EVERYTHING about cataract surgery and was considering mono vision. Now I’m just going to go with the Eyhance toric monofocal. I have astigmatism and am wanting to get rid of it to have better vision. Thank you. I know from looking at EVERYTHING- that Eyhance seems to be a very good lens. Being poor I’m only getting one shot at this, would really like the astigmatism gone, and have talked to an agency about the money needed to upgrade for a premium toric lens. I found the funding because they don’t have to pay for the whole thing, only a pair of lenses. You’re not wrong about glasses and lenses. My ins is so poor on the vision there was only one frame to get two years ago, if you needed bifocals-and it doesn’t fit me at all it’s huge. (And Too big even for fitover sunglasses which will be required after my surgery)but again only one pair to choose when you needed bifocals -and only the same ones when I returned -two years later! It’s ridiculous! They need more than one pair of frames for bifocal wearers. Hopefully this will get me to readers… I do think it’s worth it to get the premium toric but I’m not messing around with all these different focuses, and I want crisp vision. I do art and photography and am disabled so have been unable to do these activities. I may speak to my surgeon about the mono vision, but I feel much better now about readers if that’s the way I have to go or about single near vision glasses. That would help with my problems with the ins company.

Sounds like you have PCO on your operated eye. I did also, and it’s called YAG laser, and it gets rid of that so-called membrane. It’s nothing at all, it’s painless, done right in the office. Almost like an eye exam, sit in the chair, put your chin and forehead in place, and you just hear a few clicks and it’s done. Simplest procedure ever. No pain whatsoever.

"Secondary cataract" is the lay term for Posterior Capsule Opacification (PCO) as mentioned by @Mary S. That what the YAG laser is usually used for. Takes just a couple minutes and very safe.

Can’t you get glasses to improve your night vision? You didn’t mention halos but glasses will improve your contrast sensitivity if that’s your issue.

Thank you for this. I'm having a lens exchange next month because I'm having a high amount of visual effects at night, you're right about the high pressure sales towards the multifocal iol. I had the procedure done in July 2019 and the visual effects are not getting any better like they say not in my case

[@Thefloaterdoctor1]

It goes without saying that by 'promising' that you will be out of eye glasses with these premium IOLs that bar is raised - the expectations for success are much higher as well. I have heard of some doctors that will sell this as a combined procedure: The multifocal IOL + a corneal refractive procedure to 'dial it in' if needed to get it right. The prediction of which power of IOL to put in is a soft science and not always right ESPECIALLY if the patient has had previous corneal refractive procedures as that can throw off the IOL calculations. Now, for your extra $3000-$4000 you are subjecting yourself to more risk. With monofocal lenses, you just have to get it pretty close to the target since the patient will likely be prescribed glasses afterwards. By the way, the multifocal lenses do not really address the problem of pre-existing astigmatism. So there's that. Good luck with your IOL lens exchange. I hope all goes well. I think we will see more comments like yours. -Dr. J

I'm a 43 male with -5.50 in both eyes. Been wearing contacts since I was in my teens. The symptoms i'm having in my right eye with the symfony tecnis toric are; starbursts, halos, light flickering from LED lights, rings around tail lights, especially annoying while night driving or catching a movie with my family. I've been told that the visual effects will diminish or my brain will get used" to them (neural adaptation) but its honestly driving me crazy because they're still present.

I too, had multifocal lens implanted. I definitely see glare and haloes around lights and reflective signs at night. I can still drive but it is irritating. I would recommend staying with mono focal lenses based on my experience. I have noticed that the LED tail lights on cars have a fine pattern of concentric rings around them. The older incandescent types have more of a regular glare around them.

I have cataract surgery coming up in 3 weeks. Tentatively chose the PanOptix. They will start with the left eye first. I have had a few small black speck floaters for many years, and after a 50 lb weight fell from the garage overhead and hit me on top of the head recently I've had blurry areas that move left and right and back when I move my eyes. I also intermittantly have flashes of light in the periphery that go up or down depending on whether I move my eyes far left or far right, especially at night. After viewing your video I assume that means vitrious detachment but my opthamologist has not told me so. I'm beginning to think that a new lens will do nothing to improve my vision ala the blurry vitrious floaters. I need help to make a final decision on the lens. The thought of not wearing glasses is wonderful, but I also want crisp, clear vision, which means no vitrious floaters. I use my smart phone a lot, and watch tv a lot. I drive a little after dark but not a lot. I'm 70 and retired. Help?

I'm scheduled for cataract surgery very soon. I haven't received enough information so I'm researching. Yes, I've had Panoptic promoted to me. What are the odds of living with halos forever? Do you know a percentage? It was described to me as the brain learns to ignore the halos over time. I'd rather not risk a "failure to ignore" in myself. I enjoy the stars, Christmas lights, fireworks etc...I don't really want to lose those things in my long-term quality of vision and experience a "dysphotopsia" for the rest of my life. I highly value your explanation for advising your mother and ex-mother-in-law.

This is the best information on multifocal IOLs that I have found. After doing what I thought was a significant amount of research I had a PanOptix Multifocal lens put in my left eye just over a month ago. It is a disaster. 20/25 distance vision, blurry intermediate vision - it's a strain trying to read a computer screen, blurry reading - it's a strain trying to read. I live in a rural area in Canada and night vision and driving is horrific due to lack of contrast, glare, halos, starbursts. It's worse and more dangerous than with driving cataracts. Oncoming headlights are white hot blazing electric coil stove elements surrounded by two or three blazing circles. My surgeon said he wanted me to go to a pharmacy and pick a couple off the rack cheapo eyeglasses to handle the intermediate and reading ranges. He says it will be better after I get the other eye done. I cancelled the next surgery and I'm getting an appointment with another doctor to get the damn thing out and I will be getting monofocal lenses. Thank you Floater Doctor, I wish I had found you sooner.

A caveat first: I have not performed cataract surgery in a long long time. I can only go with my understanding of optics, the principles of the differences between monofocals and multifocals, feedback from many of my patients, and not least the STRONG FINANCIAL INCENTIVE for cataract surgeons to recommend the multifocal lenses. My own criteria would be similar to yours. You will see me wearing glasses in my videos...those have no power in the upper section (plano) and a little progressive reading power in the lower area. Essentially reading glasses. I do not need glasses to see super sharp at distance, and I can not imagine trading that away for the convenience (and vanity?) of the 'promise' of not needing glasses at all. If and when it is time for my to get IOLs. I'll go with monofocal lenses (both eyes) set for clear distance vision, and just wear readers as I do now.

Until now I was convinced that for an artist like me I should use the best, latest technology and was going to put tecnis synergy. Now I will start to study about monofocal lenses. Please advise about monovision When one eye is set to distance, and the other eye to near. In this case, the vision for each eye will be twice as bad? In other words: if both eyes are tuned into the distance, will my vision be better than if only one eye is tuned into the distance, and the other eye is tuned to a close distance? Thank you so much in advance! And as a bonus, can you name a couple of mono focal models?

[@Thefloaterdoctor1]

I have tried 'monovision' using a contact lens to have one eye for distance, the other for near. It will have you pretty functional for most types of general activities, but not as good as having both eyes focused equally on the object. One option is to do the monovision for most daily activities, but have some glasses you can use for your art activities/compute/reading activities to bring the distance eye in to match the already-near eye. I can't recommend a specific model as I don't do cataract surgery anymore and I am not well read on the current state of art.

I had cataract surgery July 7 and 14th received Synergy. I'm looking to others to see their experiences. My experience has not been good. I don't have "clear vision" Everything I look at seems blurry during the day outside, inside, looking at the tv, looking at the sky, the lights in my kitchen, it doesn't matter what time of day or night everything isn't clear but has glare and is blurry. I'm three months out from surgery and just had the right lens replaced with Eyehance. I have good distance and intermediate vision with the Eyehance but I'll need readers. I wanted a multifocal but with the Synergy I don't have good distance vision. When driving looking straight ahead cars are blurry and until they get close to me I can't distinguish what type of car. When I look right to turn out of my driveway I'm concerned I wont see a car coming. When I pan my vision from left to right or right to left I can't focus on anyone thing, it all just blurs in together until I stop moving my head and focus directly on one object but then there is glare around that object. In the office with eye exam I'm 20/30. They tell me I have 20/30 but it's not clear. I tell them I can read the letters but if they wanted me to read the letters I can see clearly I could only report I can't read any of them. I'm being told I'm one in one hundred people whose eyes won't adapt to the Synergy lens. But I suspect most people are having the daytime glare, blur and distance concerns. It's concerning that before surgery we are being told we will have "clear vision" for near, intermediate and far. I was told I would have some halos around lights at night and I do have that but I believe its the design of the lens that are not only causing the halos at night but also the glare and blur during the day.

This is such an excellent video, and it was this doctor's comment about monofocal lens that gave me an understanding about the quality of monofocal lens when the doctor offered to place that in my right eye, after I had such a difficult time with the multifocal synergy in my left eye. However, I was initially so sold on the synergy multifocal lens, that even if I had seen this video before I had the synergy implanted, I think I still would have opted for synergy. I feel that the KZbin and online marketing for synergy was very effective for me however I did not have the advertised results at all. In fact, when I requested the synergy that doctor was surprised that I was requesting this and was wondering why he suddenly was getting requests for synergy Iol all of a sudden. He was saying something like somebody is doing a really good marketing job for this IOL. Just like the initial writer for this reply, I have blurrys synergy vision at near distance and far in the daytime, and in the night time the contrast is so decreased, with so much concentric circles about six or eight of them with halos and glare around each light point that it's very difficult to drive with the synergy. About 6 weeks ago, I had synergy multifocal for cataract surgery in my left eye and have problems with the spider-like concentric circles night halo and glare which was problematic at night because it decreases the contrast, and plan to get it removed. On the right eye, I got the Eyhance monofocal for distance, and everything is so spectacularly hyper clear, it's like 21k, it's that clear, the distance vision for driving is so amazing it is unbelievable. Both daytime and night time for the EYHANCE lens there is no glare, no blur, however this is for distance so I need readers for cell phone and for PC for the monofocal Eyhance. The amazing thing about the monofocal e y h a n c e, there is no glare, no halo at night time, my driving at night time vision for the right eye with a monofocal e y h a n c e, is very very much clearer. However, for the left eye, for the synergy, the glare is very present, and the concentric spider web halo lights for the synergy at night time, is very distracting and difficult to see at night.

I am 6 months post cataract surgery both eyes. Both replacement lenses used were single focus. I also had my astigmatism addressed with laser treatments which was done immediately before the cataract procedure for each eye. I had to pay out of pocket for the laser treatment because it was not covered by my insurance. All post op exams were positive and suggested good results with the exception of the pressure in my right eye was above normal the day after the procedure. This was treated by eye drops and within a day the pressure in my right eye was within normal range. About 2 months after the surgery and laser treatment I began to see glare which radiated away from most white light sources when the background was dimmer or dark. Unlike the glare in your video, the dysphotopsia I experience is more like two starburst like rays and is exactly the same in each eye. For example; streetlamps and car headlights produce rays of glare in both eyes. Imagine the light source being the center of a clock; the rays extend from the light source at the 2 o'clock and 8 o'clock in both eyes. When I extending my arm and point at the light source with my index finger the rays are about one and a half to two feet in length as measured from the end of my finger. The rays are nearly as bright as the light source. This condition is both irritating and affects my driving at night. I can not find any information on a condition similar to mine. I wonder if it may have been a defect in the replacement lenses they used.

That phenomenon you describe may be better evaluated by a wavefront analysis of the quality of your optics. If there are irregular irregularity of the surface of your cornea, it could cause the glare and starburst you are describing.

How are you doing now?

Had cataract surgery in both eyes 9 months ago still painful . Told l now have dry eye which l didn't have before and have to use eye drops the rest of my life. Gone back 3 times to dr. And finally 2nd opinion was might of cut the oil glands ...😳 WHAT ? Originally l went in for floaters the year before.

[@Thefloaterdoctor1]

"Cutting the oil glands?" That doesn't make much sense to me. Cataract surgery really should cause dry eye, not in the way corneal refractive surgery like LASIK can. (edit: ...Cataract surgery should NOT cause dry eye..." Thank you @Beck H for bringing this to my attention.)

[@mortalstorm]

@@Thefloaterdoctor1 Did you mean to say, “…cataract surgery should NOT cause dry eyes?”. Is it possible for damage to occur to the oil glands during the cataract surgery?

Iam 21 years old and have myopia and wearglasses since 9 years ago and still now . Now a days I see rainbow halos around light at night and day . I don't have eye pain or head ache. What is the reason. Is it afraid to be glaucoma? When I just check my eyes by doctor by dialating the eye . She told me there no problem seeing. Should I need to be worry?.... Please please tell me please🙏

[@empem5949]

Thank you for this video....I went last week to see about getting lens replacement so I can get rid of glasses and contacts......I thought I wanted multifocal but was a bit concerned about the halos.... This vid is now making me think maybe I should go for monofocals and still have reading glasses, I wouldn't like to not be be able to not drive at night etc, which one lady in the comments mentioned. I am speaking to the surgeon for the first time on Monday about it, my 2nd visit since the testing.....I am booked in on the 10th Jan to have the surgery in both eyes.... Do you know if this happens to all mutifocal lenses....Is it a high percentage? Thank you for your content x

i have iol lens both eye 5 months ago right eye is fine i see floaters in my left eye in corner of my eye they are clear light catches the corner of my eye like light from windows light etc my dr states my retina is fine its just the gel peeling i see halo at night and star effect streaks i told my dr all this he dilated my eyes he saw no problems when i went to bed that night my eyes were still dilated when i woke up all the glare vanished and floater moved away from my corner of my eye and never returned how did this happen?

Had lasik one eye about 8 years ago for Distance and cateract surgery on other eye and mono len. After surgery glare and halo on coming traffic,vision much better but night vision while driving need to be brighter Any suggestions much appreciated.

[@saundrac9]

So suddenly I had a foggy left eye, progressively worsened over a period of a few hours, eventually, I was seeing rainbow halos around street lights. Felt better the next day, but now a couple days later, I have the fog in my right eye with the halos again, I’m very frightened, because this was so sudden. I have an appointment with my optometrist on Thursday, it’s a shame I have to wait so long, I hope I’m not going blind.

[@Thefloaterdoctor1]

It may be intermittent elevations of eye pressure cause the cornea to swell (edema). Read up on Pigment Dispersion Syndrome. I hope they figured it out.

[@TheBakingDiva]

I had cataract surgery on my right eye about two weeks ago. When I look in the mirrors in my bathrooms I see blue on my face. A week ago it was pretty dark… It look like a mask. Now it’s still there but it’s much lighter but it’s still blue. I never heard of anybody talking about this. What can you tell me? I’m having my left eye done tomorrow and I’m concerned. Waiting for a callback from my doctor. Never expected to see blue!

[@Thefloaterdoctor1]

Cataracts usually have a yellow/sepia tint to them. Much like the "Blue Blocker" sunglasses you used to see advertised. One possible explanation is that the new lens, being perfectly clear, now allows better perception of blue tones. Things may seem more blue relative to what you have been used to, a yellow-toned world. I would bet that when (if) you have the other eye done with a lens implant, the color temperature differences with normalize.

[@danielthornton6903]

I had a monofocal lens fitted in my left eye due to a cataract a few years ago which was done for free on the National Health Service (NHS) in England (I had a detached retina before this). I was wondering if the quality of lenses varies between the free NHS and what you would pay for privately. Also do some different manufacturers make better quality lenses than others and if so is the difference noticeable and is it worth paying more money for.

[@Thefloaterdoctor1]

Ignore the rumor that the NHS buys rusty old used lenses at a deep discount on the black market. It is a rumor I just started right here (OMG, I'm kidding people and NHS fanboys). Monofocal lenses are pretty standardized and have been in use since the early 70's and it was a Londoner who was the first to place one. Interesting story (look up "Sir Harold Ridley"). For me? I'd take a monofocal lens from the NHS over a 'premium multifocal lens" for my eye.

[@Jaloja]

OOo my, you just confirmed the logic of standard lens selection that I had formulated based on my uneducated gathering of "facts". I will end up with glasses regardless. May as well go with both set for distance and correct with progressive lenses that I have worn for almost 50 years. If the glasses need new lenses every few years its a easy change. I have found glasses are a safety feature and have saved my eyes. I don't "see" them as a negative at all. My interpretation of the logic makes the decision on my preference not on a desire for higher sale price. I did feel the "need "to reject my own logic to not feel cheap. Not a good reason to except the down side.

[@Thefloaterdoctor1]

[@Thefloaterdoctor1]

LAL? Light Adjustable Lens? The usual courtesy in writing is to define an acronym for the reader the first time it is used, especially for a rare, specialized or esoteric term. I have had one patient who had a LAL and was quite happy with it. So, literally 100% of my patients with LAL's have had a great experience.

[@ladym6738]

@@Thefloaterdoctor1 Oh, love the 100% and forgive for not listing light adjustable lens. Find the tweeking of the lens fascinating and it does sound like it does not have the halos, etc - as an artist, that would be a bother. Thank you for your answer.

[@saltwalk]

I'm 36 years old, had -16D in both eyes prior to ICL surgery which eventually caused cataracts to form. My new doctor really tried to push the multifocal lenses. When I told her I was scared of the same bad halo and glare I've had with my ICL lenses, she recommended lenses that could see only distance and near, but not close up. Are those kinds of lenses still considered "multifocals"?

[@Thefloaterdoctor1]

I'm not sure if I follow the second hand translation from you. Lenses can broadly be categorized as monofocal or multifocal. A monofocal lens is just that, it has a single focal point. Any lens power can be replaced into the eye and there is a formula that the doctor will follow to try to predict which is the best lens for you. There are different goals that can be aimed for. The most common might be to correct both eyes for distance with monofocal lenses. This would require reading glasses for the up close. I have not had cataract surgery but I'm blessed with good distance vision and so if you see pictures of me wearing glasses these are just reading glasses. Another option is to do monofocal target which is to set your dominant eye for distance and your non-dominant eye for a couple diopters nearsighted. This would allow you to see distance and near. Just shifting your brain's emphasis from one eye to the other depending on the activity. Another option highly promoted these days is the use of multifocal lenses which are ground and designed to try to give you both distance and near vision in the same eye. The laws of physics don't care what you're trying to accomplish or what you want, but there are limitations and sacrifices involved. If you imagine 100% of the light rays entering the eye, with a multi-focal lens, maybe 50% are focused for distance vision and the other 50% are focus for near vision. That means if you're looking at a distance object such as the visual acuity chart, you will be able to read that 20/20 probably, but there will be a soft glow around it. When you try to read up close, you'll be able to read that as well, but there will be a soft glow around it. Things will never really be perfectly crisp and sharp. That is the sacrifice you have to make when you go with multifocals. Now that might be fine if you just want to be functional, but if you are expecting crisp clear vision and or that's what you've been promised, you may be up for big disappointment.

Hi Doctor - I have a partial cataracts, dry eyes, glare and floaters in both eyes and in my left eye I have an epiretinal membrane which takes away my left eye fine detail. But what I have not yet had explained to me is what might be causing a tiny little light flicker in the centre of my left eye. My concern is it might be a nerve problem but the optometrist says my nerves at back of eye look fine. What might be causing this continual small light flicker? Is it a brain issue or perhaps a small piece if epiretinal membrane loose moving about a little (it is more noticeable in the dark with minor light)?? with thanks Breaker

I don't do cataract surgery anymore, and so I don't have professional experience with them. Optically, they should be quite good and don't suffer the tradeoffs associated with multifocal IOLs

I had a standard hydrophobic acrylic monofocal square edge iol implanted in one eye (Alcan). I have all the dysphotopsias mentioned plus long streaks at night. It's a nightmare. For my second eye, I am looking at a couple of Staar collamer lenses. They should be way better for dysphotopsia but with a 50% chance of PCO.

[@NostradAlex]

Do Toric monofocal lenses that correct astigmatism introduce glare or starbursts? I've recently had a cataract surgery and picked the monofocal toric lens that they said would also correct my astigmatism which it didn't. Premium lenses are the best. /sarcasm And now I still see everything multiple times and when I look at lights I see like a glare combined with a starburst. I still have to go for the final checkup and I'm afraid I'll still see the glare/starbursts. From what I gathered while researching the rest of the astigmatism can be corrected with glasses. But I'm afraid even if they correct the left over astigmatism, I will still see glares. Do you know if that's the case? Thanks in advance.

[@Thefloaterdoctor1]

I am probably not the ask about the use of toric lenses as I now longer do cataract surgery and do not have experience with them. They should not be a much a problem as the multifocal lenses.
