Hi Doctor. Yes, I heard this as well, in addition to possible oxidation from the bubble and air that enters the eye from surgery.
Hello, did you have YAG before the vitrectomy surgery? It’s supposed to prevent cataract. I had it done but am still have a hazy vision after vitrectomy surgery.
The exact mechanism is not know 'exactly' may be the trauma of all the instruments in the eye for a rather long surgery, could be the gas that sometimes has to be put in, can alter the position and support of the human lens.
