If a retina detachment is repaired with air-fluid exchange and no buckle put on there will be no change. If the eye is 360 degree buckled the amount varies but a ball park figure would be 1.5 diopters more myopia
Hi, I had the surgery about 5 months ago, im at about 2 diopters worse than I was before the surgery and have a slight astigmatism now, the change isnt that bad, but I have blurriness still, dont have any idea how long that will last though. I am pretty sure I am fully circled, I am still trying to get that facts straight as it is always difficult to remember things from the doctor after he has dilated my eye and shoved a light in it.
