YAG Laser Iridotomy

What is YAG laser capsulotomy?

YAG laser iridotomy is an ophthalmological procedure performed to prevent or treat certain types of glaucoma, particularly angle-closure glaucoma.

Glaucoma is a condition that can occur when the pressure inside the eye increases, damaging the optic nerve.

Iridotomy involves creating a small opening in the iris (the colored part of the eye) using a YAG laser. This opening allows the aqueous humor (the fluid inside the eye) to circulate more freely, thus preventing a rise in eye pressure and preventing permanent damage that could result.

What are the risks?

YAG laser iridotomy is generally safe, but it does carry some potential risks.

These risks include mild, temporary eye inflammation, a temporary increase in intraocular pressure, and transient blurred vision.

Some patients may also perceive light phenomena in their visual field due to the opening created in the iris, but this is generally tolerable and rare because the iridotomy is usually hidden under the upper eyelid.

Your ophthalmologist will take precautions, such as careful placement of this opening in an area minimally or not exposed to light and the use of eye drops before and after the procedure, to minimize these risks.

What happens after the laser?

YAG laser iridotomy is performed as an outpatient procedure in the doctor's office. The procedure is quick, takes approximately 5 to 10 minutes per eye, and is done under topical anesthesia, in the form of drops.

After the procedure, you can go home, although it is recommended not to drive immediately. In the hours following the procedure, you may experience slight discomfort, light sensitivity, or slightly blurred vision, but these symptoms usually disappear quickly.

Medical follow-up is essential to check intraocular pressure and ensure the eye heals properly. In most cases, iridotomy is effective and long-lasting, significantly reducing the risk of an acute angle-closure glaucoma attack.

If you experience significant pain or vision loss after the procedure, consult your ophthalmologist immediately.
