Suggest Remedy For Eye Problem
I had LASIK vision correction in 2003, and over the last couple of years since starting estrogen therapy developed new astigmatism . 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.

First development of astigmatism is just not only associated with keratectasia, it could be regression of power, corneal remodeling etc.
Hence cornea should be evaluated to cause of astigmatism. If ectasia is the cause,assessing corneal thickness by pachymetry will confirm it. Ectasia could be even due to thin residual stroma after LASIK or effect of estrogen as you are in it.
Ectasia should be serially evaluated with pachymetry as varying level of estrogen has stronger effect on cornea. Once varying level of estrogen is causing significant effect on corneal thickness.
Ideally estrogen therapy should be stopped. But if you still want to continue you should be titrated to safe constant dose which does not have much effect on corneal thickness by regular documentation of corneal thickness.
Consult ophthalmologist for thorough evaluation.
