At Karns Vision Center, we have the state-of-the-art equipment to diagnose, manage and treat glaucoma. Glaucoma can be treated by medication or surgery. First, medication is used to treat the disease. If the medication is not working, surgery is an option given. Either treatment will lower intraocular pressure and help manage the glaucoma.

Glucoma Surgery:Patients who are not able to lower the intraocular pressure with medications and continue to see a rise in pressure are encouraged to have laser or conventional surgery. If surgery is recommended to any of our patients, we will ensure that you are referred to a surgeon who is just right for you.

I appreciate Dr. Shane seeing Ralph so soon. He was the reason we went to the hospital. He did an excellent job in diagnosing Ralph as having had a stroke. If it wasn't for him there's no telling how...
