Glaucoma Surgery

What is Glaucoma Surgery?

Glaucoma surgery encompasses a range of medical procedures designed to lower intraocular pressure (IOP) in the eye, a key factor in preventing damage to the optic nerve. Glaucoma is a group of eye conditions that can lead to vision loss or blindness if untreated. Surgery is often recommended when medications or laser treatments fail to adequately control IOP. There are several types of glaucoma surgery, including trabeculectomy, tube shunt surgery, and minimally invasive glaucoma surgery (MIGS).

How is Glaucoma Surgery Performed?

The method of surgery depends on the specific type of glaucoma and the patient’s needs:

1. Trabeculectomy: Creates a new drainage pathway to reduce eye pressure.
2. Tube Shunt Surgery: Places a small tube in the eye to divert fluid.
3. Minimally Invasive Glaucoma Surgery (MIGS): Uses micro-sized devices to improve fluid drainage with minimal disruption.

Each procedure is tailored to manage intraocular pressure effectively and preserve vision.

What to Expect During the Procedure

• Glaucoma surgery is typically performed under local or general anesthesia.
• The procedure may take 30 minutes to 2 hours, depending on the technique.
• Post-surgery, patients may experience mild discomfort, blurred vision, or redness, which usually resolve within a few weeks.
• Regular follow-ups are necessary to monitor eye pressure and healing.

The Importance of Glaucoma Surgery

Glaucoma surgery is critical for preventing irreversible vision loss in advanced cases. It helps protect the optic nerve by lowering eye pressure when other treatments are insufficient. With advancements in surgical techniques, procedures like MIGS offer effective results with faster recovery times and fewer complications.
