How to make astigmatic refractions simpler

Great job.

[@madelantsao7271]

Really informative videos especially for optometry students! Would love more instructional videos like these!

Really informative videos ! Thanks for sharing How to make astigmatic refractions simpler!

Thanks a lot Kate for these wonderful skill learned, is very commendable. I am soon to start using a phoropter for my refraction 😅 so I need more complete refraction including spherical astigmatism power

[@optomly3055]

Thank you for these ideas, Kate! As a patient and even an optom student, I remember feeling nervous about not seeing a difference. Perhaps sphere could also help with bigger jumps at first, then saving the toughest question for the end? Thank you for sharing!

[@otiebrown9999]

Thank you Kate, Of course it is equally accurate to measure SPHERICAL. There is no legal requirement that cylinder be measured. I just use my own Test Lens Set. A personal choice. I prefer Spherical Equivalent. I confirm my Snellen at 20/20.

[@otiebrown9999]

I do prefer to make my own refractive STATE Measurements. Far more accurate, since I can check objectively, on a weekly basis. Accurate to 0.25 Diopters.

Thank you! It's very helpful!

Thank you!

Can you you make a video of complete eye test you would do in your office. Thanks

Thanks a lot, it was informative

You are welcome!

Can you explain why starting edtimation with power not with axis first ?

[@MyopiaProfile]

This video mentions, at the start, that the technique to 'search for cyl' is to help with small astigmatic powers. I always do retinoscopy first - if I decide to check my result with subjective refraction, I'll already be close to the cyl axis. If the astigmatism is very high, I would start with checking axis first, not cyl power.

What if your axis is completely off to to begin with?

[@deyesc6358]

I start with axis check: roughly bracket the axis if you're finding the patient is unsure, then do power check then move back to axis to confirm.

[@MyopiaProfile]

My answer - use your retinoscope to check the cyl axis beforehand, if you don't have one available from retinoscopy, autorefraction or a prior pair of glasses. If the astigmatism is very high, I would start with checking axis first, not cyl power. Hence, this comment from D eyesc is helpful.
