My cornea in the left eye is damaged after multiple glaucoma surgeries. is there anything besides cornea graft that can be done to improve vision?

Unclear...: Unfortunately, the answer to this question is unclear...As I have not seen your eyes. The best person to answer this is your ophthalomolgist; if you are not satisfied with that you might want to obtain a 2nd opinion. Given the fact that you have already had multiple surgeries makes commenting on your question more difficult.

Unfortunately not...: If your eye doctor told you that the cornea is permanently damaged, the only option that you may have are surgical. Whether caused by surgeries or the glaucoma itself, corneal damage can be difficult to treat because the cornea loses its clarity as it scars. A corneal transplant replaces the damaged "window" with a clear one, but requires close follow-up for years. Speak to your doctor.

Probably not: If multiple glaucoma surgeries have been necessary it would not be uncommon for the cornea to suffer the consequences of multiple eye surgeries. Even if the possibility for a cornea transplant is considered reasonable by the surgeon, the extent of damage to the eye nerve must also be taken into consideration. Sadly, this is usually a difficult issue to resolve.
