Argon-YAG Laser Peripheral Iridotomy

OVERVIEW

Combined Argon and Nd:YAG laser peripheral iridotomy is a proven, minimally invasive eye laser procedure used to treat and prevent angle-closure glaucoma. In this condition, the natural fluid inside the eye cannot drain properly, so eye pressure can rise quickly and damage the optic nerve. This laser treatment creates a tiny opening in the iris to improve fluid flow and stabilize eye pressure. Doctors often choose the combined laser approach because it increases precision and effectiveness, especially in thicker or more pigmented irides.

HOW THE PROCEDURE WORKS

First, the Argon laser gently thins a small area of the iris. Then, the Nd:YAG laser creates a precise opening at that prepared spot. As a result, fluid can move more freely from behind the iris to the front chamber of the eye. This step relieves blockage and reduces the risk of sudden pressure spikes. Because two laser types are used in sequence, the treatment is more controlled and often requires less total energy.

WHO MAY BENEFIT

This procedure is commonly recommended for patients with narrow angles, angle-closure suspects, or angle-closure glaucoma. It may also be advised for patients who already had an angle-closure attack in one eye, since the other eye often shares similar anatomy. After examination and imaging, your ophthalmologist will confirm whether this laser treatment is appropriate for your case.

KEY BENEFITS

Combined Argon and Nd:YAG laser peripheral iridotomy offers several clinical advantages.

1. Helps prevent acute angle-closure attacks.

2. Lowers the risk of permanent optic nerve damage.

3. Uses a non-incisional, outpatient laser technique.

4. Typically completed within minutes.

5. Supported by long-standing clinical studies and international practice guidelines.

WHAT TO EXPECT DURING TREATMENT

Before the procedure, the eye is numbed with drops and a special contact lens is placed for accuracy. The laser treatment itself usually takes only a few minutes. You may notice brief flashes of light and mild discomfort; however, most patients tolerate the procedure well. Afterward, you can usually go home the same day. Your doctor will check your eye pressure and may prescribe anti-inflammatory drops.

RECOVERY AND AFTERCARE

Most patients resume normal daily activities within a day. Mild redness, light sensitivity, or a temporary headache may occur, but these effects usually settle quickly. Follow-up visits are essential because your doctor must confirm that the opening remains patent and that eye pressure stays controlled.

SAFETY AND EVIDENCE BASIS

Ophthalmologists worldwide use combined Argon and Nd:YAG laser peripheral iridotomy as a standard, evidence-based intervention for angle-closure disease. Peer-reviewed studies and specialty society guidelines support its safety and effectiveness when performed by a qualified ophthalmologist. Individual results, however, vary, so personalized evaluation and follow-up remain essential.
