How would you go about getting a subjective refractive without an auto refraction?

Was the first eye and example of a perfect or near perfect cornea?

I check every day. Back to 20/20.

Hi can you help me with a problem i have with an Alpha d camera. Thank you

Worst test...false positives and negatives and if you get distracted easily, the results are worse. The new and improved version is virtual and you follow the lights naturally with each eye, not fix your eye on a spot and don't move it. Much better results.

I hope you don't watch this video, this person should find another job

Difference between plus and minus in regards to cylinder?

Thank you Ryan your explanation is very clear .

Can you send me the computer software? Thank you

Easy and simple

Is it necessary to enter the keratometry? Can you use those of an autorefractometer?

Amazing ! Thank you .

Great Video !!

Kindly help me how to calibrate

Very nice

Hello Sir, is there any way to see chambers with this machine? for example anterior chamber?

I have watched many tutorials on refractions. Your video was the BEST especially with showing refining cylinder axis which was never explained clearly. Thank you!

How to improve corneal thickness

This has confused me... Other tutorials say that when in minus cyl, you "chase" the white dots to configure axis.... you said, chase the red dots.... very diametrically opposite... So which is it?

What about the blue marks on each side? and the + signs on the eye, how do you center those?

Super clear and easy to follow. Thank you.

This test can detect episode contra eye surgery or not

Thank you 🙏 tomorrow I got osce it is helpful..

Price?

I recenlty started refracting at my job and this video helped a lot, you make it so simple. Thank You for taking the time to do this.

Thanks. Helpful for me.

This is not a good instruction on getting a high quality image. Good scans should be 8,9, or 10. Zeiss themselves have videos on KZbin on how to achieve this, would recommend viewing those instead.

Does the sound correspond to every click or it’s an indication of the appearance of the blinking light

okay but what is the air puff one called

Why does the doctor only use 24-2?

How to archive all data in HDD?

In nerve fibre what are the two scans

Excellent tutorial! My one problem is when you're starting with 0 cyl. I am not familiar with "fishing for cyl" and do not know how to refract with that kind of starting point.

What is I can’t see the patients eye on the screen?

I had this test done yesterday (8/30/2021). This is very good. But what is missing is any rendition of what the patient sees when looking through the lens!!

Hi, for 'poor cornea' what do we need to do adjustment so that we can get the measurements using immersion method?

The funny this is, that the person that came up with this said it is crude and shouldn't be used for testing for peoples ability to drive. Was only design to get a rough idea of the medical conditions.

Contoura or IDesign ? Which one is Best ?

Hola tendrás el software del equipo

Hello sir , I'm from india ... Can you tell OTC and Corneal topography is same or different ?

U turned it on Angio mode at starting itself

Artifact at right-down position

Nice tutorial. But you're leaving out the magic of composition.

Hello! I would appreciate it if you could send me the tms-4 software. Thank you!

open WIDE with your eyes. keep the pupil in the center once set up is done. we do set up: enter pt id, name and bday and enter eyeglass Rx or zero if no distance is used. if patient is using contacts for distance, enter 0 and 0 - do not leave blank make sure the correct trail lens is used! a. wipe down the machine b. explain the test c. put the patch on - be careful with the band! d. have patient pull up all the way and sit up straight an comfortable e. let the technician raise the table to the pt chin. f. rest chin on chin rest, teeth together THEN put forehead against the top 1. center pupil to cross while looking at yellow light 2. look down into the diamond - press the button when you see a light flash inside the diamond 3. look back into the yellow light (on cross hair) for 10 seconds to activate gaze tracker 4. back to the yellow light, center pupil inside of the lens and begin test 5. SAVE at the end monitor pt eye movement - they must stay fixated very easy and relaxed on the yellow light acknowledge the flashing pinpoints by pressing the button if it is too fast, slow the stimuli lights if the pt appears tired, stop the test and offer them a chance to take a break if the patient is making too many errors, stop and clarify as needed before going too long
