Sloping To The Left

[iD]

so I had volunteered to adjust glasses for low income families who got their glasses from another optical office. which in hindsight I knew was going to cause some problems for me.

I had one lady come in and she says everything is sloping down to the left. Her distance is fine. Her reading is fine except for that slant. No double vision. She's had cataract surgery before. She's in a bifocal 28 and that's as much as I can tell. I was trying to adjust it and can't seem to make it better. What would you guys conclude the problem to be?

A type of anisometropia.

She probably has a pocketbook-ful of surgically-induced astigmatism, both minus cylinder axis 45-ish (or 135-ish or something).

Hispanics are notorious for their astigmatism, also. Was she a senora?

[iD]

she was not a senorita. She was a Caucasian lady around mid to late 60's.

Any info about the lens powers?

I just had a post-cat customer (yes, a Senor) with the same problem. Wore progressives for years, then after cataract surgery I made him progressives and he complains about everything sloping. New Rx is about 1.5D cyl, and I believe that is absolutely the culprit (maybe was near spherical pre-surgery?). Sent him back to his OMD for re-refraction and he cut it to 1D cyl, which helped but it's still there. Only solution now is to just wear the darn things and let the brain rewire and adapt. He hasn't been back in a month so he's either adapting or the glasses are gathering dust in a drawer...

I forgot to write it down.

The brain needs to relearn what a straight line looks like. The slanting usually goes away in about 10 days.

I filled RXs from an older cataract surgeon in the early 1980's who sutured the incisions so tight that the refractions typically yielded 4 DC, with an occasional 5 DC or more, usually with-the-rule I think. Fortunately, very few were wearing PALs at the time.

Ahhhh, those were the days. In the late sixties I believe most of the surgeons were using "open sky" procedures and massive amounts of astigmatism could be induced and in many cases were induced. The real problems was the irregular astigmatism where the topography of the cornea was similar to the contra ocular surface of a progressive lens.
