Hello everybody.
A few years back I asked for help and received quite a few extremely helpful answers regarding surfacing, so I figure I'd try for seconds.
I'm curious if anyone can explain (with out to much technical jargon) what equithining prism in a PAL is used for besides cosmetics, and how (or if) it is of benefit to the patient.
From what I understand a small amount of od/os matching equithin is acceptable due to processing difficulties, but I am curious everytime I see an RX come through with 3+ diopters prescribed.
Thank you in advance!
