Dear Vikas, after hearing your case I can tell that you have advanced keratokonus in your right eye as compared to left eye.Post hydrops ( break in the descemets membrane in cornea which causes stromal edema) the stromal edema of cornea subsides and later you may develop scarring.Later the scarring subsides but doesn t go fully.Now if you have a good vision after the hydrops and comfortable with RGP lens then continue the same.But if you don t have good vision and RGP lens is not fitting properly ,you can undergo corneal transplant.I will advise you to undergo corneal transplant if your right eye is nonfunctional, post hydrops and you are managing only with the left eye .Post transplant you vision will definitely improve and if you follow proper instructions and have a regular follow up the chances of graft failure , rejection, glaucoma , infections and other side effects are minimal.Since you have not mentioned the present vision in your right eye I can only say go to a good corneal surgeon and discuss your case.Two functional eyes is better than one functional eye.If you have not undergone collagen cross linkage for your left eye, go for it as it helps to restrict the progression of keratoconus.So do a corneal topography and discuss with your eye specialist who can help out to perform these procedures...TC and have safe eyes...DR Ajay Shankar Kar, Cornea consultant,Sankar Eye Foundation,Visakhapatnam.
