Post Cataract

[Tuckvale]

Post cataract patient is having trouble with glasses prescription, has had post op varifocal lenses.  Is post op in Left eye, cannot manage with glasses, I suggested that she shouldn't have to get used to the glasses.  Had second refraction with another optometrist.  Told she would have to have separate glasses for reading and distance. The prescription suggested that the problems were  Anisiometropia,  Decompensating exophoria, therefore needing prism s,  this lady has never had prisms before in her life, only started wearing glasses in later life. The first prescription at post op no problems were found.   Can you answer why she needs prisms after cataract surgery please.

We need more information. What are the actual prescriptions? Has she had the surgery in both eyes or only in one? How strong were her reading glasses before she had the surgery?

Anisometropia means here eyes are too different in prescription to be corrected by glasses properly. This alone can cause a world of problems.
If she had a certain type of anaesthetic used during her surgery this can cause muscle problems which can cause slight double vision which means she would now need prisms in her glasses. If she had a mild cataract in one eye for a very long time and never realized it she may have a slower eye which can also cause this. She may have been born this way and it was never a problem because she never needed glasses for distance before. The surgically induced anisometropia can also cause double vision which they might try to fix by putting prisms in her glasses

Have her try contact lenses for distance and using reading glasses. Does that solve her problems?
"Adjusting" to glasses for me actually meant "you'll get used to seeing poorly and being dizzy and nauseous all the time while you strain your neck because you have to hold your head at strange angles to see clearly, you can get used to living in an aquarium. The walking into walls, you'll get used to that too. And the splitting headaches, well they have pills for that". And my glasses were single vision, I can't imagine the horrors I would have gone through if they were varifocal. Glasses simply aren't an option for me but my vision is perfect in contacts.
The same thing happened to my coworker when she first  needed varifocals. No surgery, she just got older. She complained she was blind for six months and then eventually stopped complaing because the doctors kept telling her everything was fine. She can't see any better than she could before, she just doesn't complain anymore.

I am confused by your post.  You start out saying she can't manage with the post op varifocal glasses and then you state that the first script post op had no problems.  Please clarify.
