I have been fighting glaucoma for over 30 years. That just meain I need eye drops to reduce the pressure in my eyes. Many people can control it with just one eye drop daily. I am currently on 3 eye drops: Pilocarpine, Dorzolimide, and Rocklatan. Are you seeing a board certified optomologist? They can prescribe best eye drops for your case, and tell you when it is time to have cataract surgery.
