I would suggest against tPRK. C3r may be needed if there is progression.

If you have keratoconus disease,it may slowly progress to thin cornea. 10 to 15 days rest is necessary. You can go ahead with the operation. It will be helpful.

Hello, I'll try to clear your doubt in sequence 1) No we don't have thin cornea since childhood normally, You have keratoconus diseases in which it slowly progress and cause thinning with age 2) 1- 2 week rest is sufficient 3) C3R is must to avoid further progression of keratoconus, if you have contact lens intolerance then you can go ahead with TPRK with C3R
