On bimatoprost ( lumigan). Have noticed bulge, looks like I'm wearing a contact lens

Hello everyone, I wonder if anyone can comment on this. At my last two eye appointments, when my consultant was examining my eyes, he asked if I was wearing a contact lens on my left eye. This was surprising as had not mentioned this on previous examinations , and anyway I wear glasses. I checked myself and yes, there is a curve over my iris and it looks like there's a clear contact lens. I've been taking bimatoprost or similar ' prost' drops in my left eye since diagnosis 9 months ago. I have the usual side effects of a sunken dark eye (depressing) and thicker eyelashes ( nice!). Otherwise eye looks fine. I had a corneal graft in this eye for keratoconus about 20 years ago and they took the lens out at the same time .

I don't have the same appearance in my right eye where glaucoma is worse. I have Hydrus shunt and dorzolamide drops. Bimatoprost was discontinued beginning of December.

Hello. The only thing that I can think, could be causing what your eye specialist and you are both seeing in your eye, is where you had the corneal graft. Your eye specialist would be aware of this though. Obviously, they didn't comment on it, after they asked about the contact lens. The only way to find out is to ask them. I am not aware that Bimatoprost or any eye drops would cause this effect.

Thank you Helen. I'll ask for clarification at my next appointment. My brown eye colour has noticeably darkened with the eye drops so maybe that just highlights an aspect of the shape of my cornea that was there all along.
