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
Thank you thank you thank you!!!
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?
U see that the cylinder value in this phoroptor is red so u chase the red dot if the cylinder value is in black u chase the white dot ! In this video this phoroptor use a minus cyl so he will chase the red dot
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 CZcams on how to achieve this, would recommend viewing those instead.
The point of the video is just to show step by step instructions on how to take a scan and what you are looking at. Obviously a poor quality scan under 8 can be from many factors like cataracts, edema, or patient moving/blinking. Sometimes you can achieve a better scan by redoing it, but other times you might never achieve it.
@@ryantourt4241 exactly!! It would be a piece of cake if we had pts that could keep their eye still, or even see the target to know where to hold their eye. It’s hard to get a perfect scan on those.
Does the sound correspond to every click or it’s an indication of the appearance of the blinking light
Each time you click. Be warned, if you have used a good quality Mouse or a clicker, & use to a proper and a quick tone feedback. This machine will drive you nuts. Modern gadgets have spoilt us. The feedback from the clicker is like using the most pathetic keyboard, ever. Which i am still to encounter.
okay but what is the air puff one called
It measures eye tension.i could not keep my eyes open lol.i jumpscared even though i knew it would blow
It’s the NCT (Non-Contact Tonometer) It measures your intraocular pressure.
Thank you, you cleared everything for me
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.
you just put the jcc so that power is at 90/180 and ask what is better. then at 45/135 and ask again. if the patient prefers any position then they probably have cyl around that axis. so you can now insert -0.5 cyl and start refining axis and power
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
disculpa conseguiste el sofwer??
I need one nidek AR
Hello sir , I'm from india ... Can you tell OTC and Corneal topography is same or different ?
Kya problem h bhai tuje
OCT scans the back of the eye and can scan anterior segment with a special lens. Corneal topo measures the corneal curvature

Correct, these videos were just made to help staff navigate our office equipment
Nice tutorial. But you're leaving out the magic of composition.
