Glaucoma Surgery Procedure Explained Step by Step

Glaucoma is a serious eye condition that can gradually lead to vision loss if not treated in time. For many patients in India, especially those seeking reliable and affordable care, understanding the glaucoma surgery procedure can help reduce fear and encourage timely treatment.

At DrishtiCare, we prioritize patient awareness along with advanced treatment options. This guide explains the glaucoma surgery process step by step, so you know exactly what to expect.

What is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, usually due to high intraocular pressure (IOP). If left untreated, it can lead to permanent blindness. Surgery is often recommended when medications or laser treatments are not enough to control eye pressure.

When is Glaucoma Surgery Needed?

Your eye specialist may recommend surgery if:

• Eye drops or medications are not effective

• Eye pressure remains high despite treatment

• There is progressive vision loss

• You cannot tolerate medications due to side effects

Types of Glaucoma Surgery-

Before diving into the procedure, it’s important to know that there are different surgical options:

• Trabeculectomy (most common)

• Glaucoma drainage implants

• Minimally invasive glaucoma surgery (MIGS)

Your doctor will recommend the best option based on your condition.

Glaucoma Surgery Procedure: Step-by-Step

Step 1: Pre-Surgery Evaluation

Before surgery, your doctor will conduct:

• Eye pressure measurement

• Visual field tests

• Optic nerve examination

• General health assessment

You may be advised to stop certain medications before surgery.

Step 2: Anesthesia Administration

On the day of surgery:

• Local anesthesia is usually given to numb the eye

• You will remain awake but won’t feel pain

• Mild sedation may be provided for comfort

Step 3: Creating a Drainage Pathway

This is the most important step:

• The surgeon creates a small opening in the eye (in trabeculectomy)

• This allows excess fluid (aqueous humor) to drain out

• Reduces pressure inside the eye

In some cases, a tiny implant or tube may be inserted to help fluid drainage.

Step 4: Placement of a Drainage Bleb

• A small reservoir called a bleb is formed under the eyelid

• This collects the drained fluid

• Helps maintain normal eye pressure

Step 5: Closing the Incision

• The surgeon carefully closes the surgical site with tiny stitches

• The procedure typically takes 30–60 minutes

After the Surgery: Recovery Process

Immediate Post-Operative Care

• You may go home the same day

• Eye will be covered with a protective shield

• Mild discomfort, redness, or blurred vision is normal

Medications-

You will be prescribed:

• Antibiotic eye drops

• Anti-inflammatory drops

• Sometimes pressure-lowering medications

Follow-Up Visits-

Regular check-ups are crucial:

• To monitor eye pressure

• To ensure proper healing

• To prevent complications

Recovery Timeline-

• First few days: Mild irritation and blurry vision

• 1–2 weeks: Gradual improvement

• 4–6 weeks: Stabilization of vision and pressure

Full recovery may vary depending on the type of surgery.

Risks and Complications-

Like any surgery, glaucoma surgery carries some risks:

• Infection

• Bleeding

• Temporary vision changes

• Low eye pressure

However, with experienced surgeons and proper care, complications are rare.
