Solution or cure to glaucoma?

My hubby has glaucoma and it is not a hard condition to deal with. He uses 2 different kinds of eye drops every day and another at night. He use to have a hard time remembering, but we put the drops by his bedside and he uses them before he gets up in the morning and before he goes to bed at night. He has had laser surgery twice and it is simple too. No pain or anything. It lowers the pressure within the eye. You do need a good doctor whose specialty is glaucoma. We went to the Eye Institute in Dallas.
