Glaucoma results in raised intraocular pressure and vision loss over time. Unfortunately, surgery for glaucoma cannot reverse this vision loss. However, surgery can reduce the intraocular pressure when medication is not a sufficient solution. If necessary, glaucoma surgery can be performed multiple times with low risk.
There are two kind of common glaucoma surgery: laser and conventional.
Laser Surgery – During laser surgery, a laser is used to make a small opening in the eye’s drainage system to help increase fluid drainage out of the eye. When laser surgery unable to solve the condition & condition re-emerges, the ophthalmologist may refer for conventional surgery.
Conventional Surgery – During conventional surgery, a new drainage canal is created that allows intraocular fluid to flow out of the eye.
