Laser iridotomy treats or prevents angle-closure glaucoma, a condition where the iris presses against the cornea and blocks fluid drainage. By creating a small aperture at the iris’s edge, this procedure restores proper fluid flow between the front (anterior) and back (posterior) chambers, helping to reduce or reverse elevated intraocular pressure.
Procedure summary
Anaesthesia
Performed under topical (local) anaesthesia—completely painless.
Surgical Technique
A focused laser beam is used to make a small hole in the outer edge of the iris, allowing fluid to circulate freely and opening the drainage angle.
Quick and Efficient
Often completed in a single visit with minimal preparation and no stitches required.
Potential risks & side effects
After the procedure, a few transient side effects may occur, including:
- Blurred vision for a short time
- Mild bleeding
- Corneal swelling
- Temporary increases in eye pressure
- Persistence or closure of the opening
- Glare or double vision
- Development of a different form of glaucoma
Although rare, these potential issues underscore the importance of close follow-up care.
Clinical benefits
- Provides rapid reduction of risk for acute angle-closure glaucoma
- Prevents vision loss by ensuring consistent aqueous humour flow
- Quick recovery with minimal discomfort or downtime
- Suitable as either a preventive or emergency intervention
