I know there is cataract surgery. Not sure if there is one for glaucoma.
FReepers?
What is the treatment for glaucoma?
General approach
Although nerve damage and visual loss from glaucoma cannot usually be reversed, glaucoma is a disease that can generally be controlled. That is, treatment can make the intraocular pressure normal and, therefore, prevent or retard further nerve damage and visual loss. Treatment may involve the use of eyedrops, pills (rarely), laser ,or surgery.
