Laser iridotomy for glaucoma
What To Expect After Surgery
Why It Is Done
Laser iridotomy is used to:
- Treat closed-angle glaucoma after the pressure in the affected eye has been reduced with medicine or when medicines fail.
- Prevent closed-angle glaucoma in people who have narrow drainage angles and those people who have had closed-angle glaucoma in their other eye.
How Well It Works
- Laser iridotomy can prevent further episodes of sudden (acute) closed-angle glaucoma.
- Laser iridotomy can usually prevent slow-forming (subacute) closed-angle glaucoma in people who are at risk for closed-angle glaucoma.
- Sometimes people can take less medicine to treat glaucoma after having laser iridotomy.
- Brief blurred vision (common).
- Swelling of the clear covering (cornea) of the iris.
- Increased pressure in the eye.
- Closure of the new opening. A second surgery might be needed if the new opening closes.
- Burn to the inner lining of the eye (retinal burn). This is a very rare complication.
- Worsening of clouding of the lens (cataract) that was present before laser treatment.
- Closure of the opening.
- Recurrent closed-angle glaucoma.
- Development of another type of glaucoma.
- Continuing need for medicines (depends on the person's condition before laser treatment).
- Glare from light entering through the new opening.
