Glaucoma is a group of eye diseases that damage the optic nerve, which carries visual information from the eye to the brain. Glaucoma is often caused by increased eye pressure, but it can also occur in people with normal eye pressure.

     Glaucoma is a leading cause of blindness in adults, but it is often preventable with early detection and treatment. However, in some cases, surgery may be necessary to lower eye pressure and prevent vision loss.

When is surgery necessary for glaucoma?

Surgery may be recommended for glaucoma if:

• Eye drops or laser surgery have not been effective in lowering eye pressure.
• Eye pressure is very high and is causing damage to the optic nerve.
• Glaucoma is causing vision loss.
• Glaucoma is associated with other eye problems, such as cataracts.

Types of glaucoma surgery

There are two main types of glaucoma surgery:

• Trabeculectomy: This is the most common type of glaucoma surgery. It involves creating a new drainage channel in the eye to allow fluid to escape more easily.
• Tube shunt surgery: This type of surgery involves placing a small tube in the eye to drain fluid into another part of the eye or to the surface of the eye.

Minimally invasive glaucoma surgery (MIGS)

     MIGS is a newer group of glaucoma surgeries that are less invasive and have shorter recovery times than traditional glaucoma surgeries. MIGS procedures are often combined with cataract surgery.

Risks and benefits of glaucoma surgery

Glaucoma surgery is a safe and effective procedure, but there are some risks, such as:

• Infection
• Bleeding
• Cataracts
• Scarring
• Low eye pressure

     The benefits of glaucoma surgery usually outweigh the risks. Glaucoma surgery can lower eye pressure and prevent vision loss.

How to prepare for glaucoma surgery

     Your doctor will give you specific instructions on how to prepare for glaucoma surgery. These instructions may include:

• Stopping certain medications
• Having someone drive you to and from surgery

What to expect after glaucoma surgery

After glaucoma surgery, you will need to rest and avoid strenuous activity. You will also need to take eye drops and medications to prevent infection and inflammation.

Most people recover from glaucoma surgery within a few weeks. However, it is important to follow your doctor’s instructions carefully and to attend all follow-up appointments.

Here are some additional tips for people considering glaucoma surgery:

• Ask your doctor about all of your treatment options and the risks and benefits of each.
• Make sure you have a good support system in place to help you recover from surgery.
• Be patient and follow your doctor’s instructions carefully.
