Nd Laser Peripheral Iridotomy (LPI/PI) is a minimally invasive laser procedure used to help prevent or manage certain forms of angle-closure glaucoma and narrow-angle conditions. It creates a tiny opening in the peripheral iris, allowing fluid inside the eye to flow more freely and helping reduce the risk of increased eye pressure in suitable patients.
When Is Laser Peripheral Iridotomy Recommended?
An ophthalmologist may recommend laser peripheral iridotomy after examining the drainage angle and assessing eye pressure and other risk factors. It is commonly considered for eyes with anatomically narrow angles or certain types of angle closure. Your doctor will determine whether LPI is appropriate based on your individual eye condition.
What Happens During the Procedure?
The eye is numbed with topical anaesthetic drops, and a special contact lens may be placed on the eye to help focus the laser. The Nd laser is then used to create a very small opening in the iris. The procedure is generally performed on an outpatient basis and usually takes only a short time.
Recovery and Aftercare
Mild redness, light sensitivity, blurred vision, or discomfort can occur temporarily after laser iridotomy. Your ophthalmologist may prescribe eye drops and recommend a follow-up examination to check eye pressure and the response to treatment. Seek prompt medical attention if you experience severe eye pain, significant vision loss, or other concerning symptoms.
