LDD treatments for the Light Adjustable Lens | My approach to Light Treatments for the LAL

Within a healthy eye is a clear lens. As we become older, that lens becomes cloudy. The cloudy lens is called a Cataract. In cataract surgery, the cloudy lens is removed and replaced with a clear artificial lens implant.
In this video, I plan and perform light treatments on my Father In-Law with the LDD (Light Delivery Device). Join me as a perform the LDD treatments and test his vision.
LDD treatments are performed after Cataract Surgery or Refractive Lens Exchange has been performed with the Light Adjustable lens (LAL).
If you have any questions, feel free to leave them in the comment section below!

What a great video to show the LDD process. Any difference you have seen with the LAL and LAL+ both in performance and also in nuances of doing the LDD?

[@tryalsryder]

I am 58 and I have cataracts. I did all of my testing last Friday. I had Lasik years ago and Vitrectomy in both eyes last year and a slight astigmatism in one eye. My surgeon either recommends the standard lenses or the LAL. I go in the office tomorrow to speak with the scheduler and discuss costs. I know I will have sticker shock when I hear the price, but it's my eyesight, so I will do what's best for my eyes. After watching your 3 part video with your father-in-law, I would definitely come to see you. If only you were in Virginia! Thanks for posting such informative videos. You have helped ease my mind about my surgery.

Thanks so much for your kind words. Best of luck to you!

Excellent review and example.

[@ustatsingh4396]

hello doctor . Can u please tell me which is better between J&J Technis Eyehance monofocal AND Alcon Clareon monofocal. My Dr said both are equally good and I can choose any for my surgery. Is my doctor missing something ? Which one should i go for ?

[@user-ne8ci9iq8p]

Are these 2 the best monofocal lenses or LAL is better than these two ?

[@harshutswal7308]

Can u tell me the best monofocal lens ? Iam facing similar situation. LAL is not avilable in my country.

[@DoctorKrad]

They are similar in that they are both monofocal lenses, but the eyhance has about 0.4 diopters more depth of focus. With either lens implant targeted for far distance, you will need glasses for computer and reading up close. If you have corneal astigmatism of 1 diopter or more, then your vision for far distance will be better with glasses that correct the astigmatism

[@DoctorKrad]

They are both excellent monofocals, but the LAL is King (at the moment)

[@ustatsingh4396]

@@DoctorKrad ty so much doctor. I have 0.75 astigmatism. My doctor said no toric lens is available for less than 1 dioptre astigmatism, but he said he will correct my astigmatism during surgery. I have decided to go for Phaco + Clareon monofocal. (I went for clareon monofocal because it is covered by my insurance. Sadly they consider technis eyehance as premium lens here so it was not covered by insurance.) Unfortunately , LAL is not available in my country and I could not find a doctor here who even knew about LAL 😅 My surgery is scheduled on 3 October. 😄❣️

I just had my right eye done with LAL and it's my dominant eye which is being targeted for distance (so we didn't do this 'trick' with the machine). I plan to get the left eye done eventually and I assume LAL would probably be my best option and my Dr. stated we could do a "mini-mono" would you recommend doing this sort of adjustment for the left eye if it's being targeted for up-close so I don't lose distance? Thank you in advance.

Hello Dr Krad, I recently got an LAL+ in part because of your great videos about the LAL. I asked my doctor about stretching the DOF at the first LDD like you have discussed, but he says that isn't done with the LAL+, only with the original LAL. Is that true? I'm looking for second opinions before my first LDD adjustment in a couple of weeks.

[@mromito15]

I don’t understand what the purpose is of inputting the incorrect refraction instead of merely inputting the correct refraction and putting this change in the target refraction. Is not the actual treatment the same, the delta between the MRx and the target?

[@DoctorKrad]

The delta is the same, however the treatment changes only IF the target refraction is -0.50 or greater. The LDD is engineered to add slightly extra negative spherical aberration if targeting -0.5 or greater, despite the equal delta.

[@RebekahsZ]

Could you please pull harder when you are moving the reading material away? I’ve heard people complain that their arms have gotten short! Maybe you can fix this by pulling harder?

[@nevermindwydad]

Are you checking his vision right after the LDD session? My eyes were so blurry after!

Different days, the patient is wearing different shirts. As much as they dilate your eyes, I can't see squat.
