I had LASIK vision correction in 2003. I read that a side effect of estrogen is corneal steepening, changes in the curve of the cornea, and a concern for LASIK patients since their corneas are already weakend which the estrogen may cause a bulging cornea. Does anyone know if the cornea changes are progressive or will they stop. I am very worried about this. I want to be on estrogen for many more years, I am 31 yrs. old.
