YAG Peripheral Iridotomy (YAG PI) in Mumbai – Kurla BKC, Kalina & Bandra W

Angle-closure glaucoma is a condition where the iris blocks the eye's drainage channel, causing eye pressure to spike suddenly and dangerously. YAG Peripheral Iridotomy is a simple, quick laser procedure that creates a tiny opening in the iris to allow fluid to flow freely — preventing an acute attack or treating the underlying cause in chronic angle closure.

What Is YAG Peripheral Iridotomy (YAG PI)?

A YAG laser creates a microscopic hole in the peripheral iris (away from the visual axis). This opening acts as an alternative drainage route, equalising pressure across the iris and preventing the pupil block that triggers angle-closure attacks. The procedure is permanent and takes only a few minutes.

Who Is It For?

This procedure is generally suited to patients meeting the following criteria:

Narrow angles identified on gonioscopy (preventive YAG PI)
Acute angle-closure glaucoma (emergency treatment)
Chronic angle-closure glaucoma
Fellow eye of a patient who has had an acute attack

What Happens During the Procedure?

Each step is performed with precision and patient comfort in mind.

Step 1: Constricting drops applied to the iris
Step 2: A contact lens placed on the eye for stability
Step 3: YAG laser creates one or two small openings in the peripheral iris
Step 4: Procedure completed in under 5 minutes

Recovery & What to Expect

Mild blurring and light sensitivity for a few hours. A single follow-up visit confirms the opening is adequate and that pressure has not risen post-procedure.

Benefits

Patients choosing this procedure typically experience the following benefits:

Prevents potentially blinding acute glaucoma attacks
Permanent, one-time procedure in most cases
No incision, no recovery period
Can be done preventively in high-risk eyes

FAQFrequently Asked Questions

Is YAG PI performed in the clinic?

Yes — it is done at the slit lamp in our clinic. No operating theatre is required.

Is it painful?

Patients feel a sensation like a small tap. Anaesthetic drops are used — no injections needed.

Will it affect my vision?

The opening is in the periphery of the iris and does not affect the visual field. Rarely, patients notice a faint line at the edge of their vision — this usually becomes unnoticeable within a few weeks.
