I recently did a PRK due to my cornea is thin my doctor prescribed me to use FML eye drops. Which I read it can thin out the cornea and can also cause high eye pressure. The dosage he told me was for the first week 4 drops each day 4 separate times then second week 3 drops per day the 3rd week 2 drops per day and 4 th week 1 drop per day so what I want to know is there a big risk?
