I had prk in both eyes 2011. Then prk enhancement in 2015. Then left eye had spontaneous retinal tear 5 months after the enhancement, it was lasered but left me with huge floaters. 3 months later Retinal hole in the left eye which was again lasered. Now both eyes have regressed again. I can't tell if the blurry vision is from the floaters, the regression or from the epiretinal membrane. Would another enhancement to the left eye be risky?
