I was born premature in 1966 and have retinal damage (retinopathy of prematurity) from prenatal oxygen. I have 20/200 in the left eye and 20/40 on a good day corrected in the right eye. However, there was some drifting of the central portion of my retina in the right eye so I do not see exactly out of the center, therefore I have had difficulty getting a correct prescription that offsets the optical centers of the glasses so that I am actually viewing through the strongest (prescribed) portion of the lens. We have tried guessing a smaller PD than the standard measurements, but it's not very exact. To make this even worse, I have a very strong prescription with high astigmatism (-8.00 125 cyl) so any error in guessing the correct PD makes the glasses quite ineffective.
They are able to make up a trial set with the correct Rx, but I'm not getting the same acuity in the prescribed glasses without physically shifting them over a few millimeters to look thru the strongest part.
Is there a procedure for measuring this discrepancy so that eyeglasses with the correct PD can be manufactured? I have been to see many OD's but no one seems to have a handle on it, and of course, opthamologists are out of the eyeglasses biz these days.
