This topic will help you understand glaucoma surgery and how to prepare for it.
What Is the Glaucoma Surgery Procedure?
Glaucoma surgery aims to reduce eye pressure by draining the aqueous humor. There are two types of glaucoma surgery:
- Trabeculectomy: This involves creating a small opening in the upper part of the eye to allow the aqueous humor to drain.
- Valve Implantation: This involves implanting a valve or a small tube in the eye to help drain the aqueous humor.
When Is Glaucoma Surgery Performed?
If medications (drops) and laser treatments fail to lower eye pressure, the doctor may resort to surgery.
How To Prepare for Glaucoma Surgery?
- Your doctor will ask you to sign a consent form granting permission for the procedure. Read the form carefully and ask questions if anything is unclear.
- You will be asked about the last time you ate. If the procedure requires anesthesia, you will be asked not to eat or drink for 8 hours before the procedure.
- Inform your doctor if you have any allergies to medication or anesthesia.
- Inform your doctor of all medications (prescription and over-the-counter), vitamins, herbs, and supplements you take.
- Inform your doctor if you have a history of bleeding disorders or if you are taking any blood-thinning medications (anticoagulants), aspirin, or other drugs that affect blood clotting. You may be asked to stop these medications before the procedure.
- You may be given medication to reduce stomach acid, which also helps dry secretions in your mouth and airways.
- Follow any other instructions your doctor provides to prepare.
- Make sure you have someone to accompany you after the surgery.
