ND:YAG LASER IRIDOTOMY
Nd:YAG Laser Iridotomy is a precise, non-incisional laser procedure that creates a tiny opening in the peripheral iris to improve fluid flow inside the eye. Ophthalmologists commonly recommend this service to prevent or treat angle-closure glaucoma. As a result, pressure inside the eye can stabilize, and the risk of sudden pressure spikes can decrease.
WHAT THIS SERVICE DOES
Fluid inside the eye normally flows from behind the iris to the front chamber. However, in narrow or crowded angles, the iris can block this pathway. Consequently, eye pressure may rise quickly and threaten vision. Nd:YAG Laser Iridotomy forms a small bypass opening in the iris. Therefore, fluid can circulate more freely and pressure can equalize between chambers.
COMMON CLINICAL INDICATIONS
Your ophthalmologist may advise this laser service after careful examination and angle assessment. For example, it plays a key role in glaucoma prevention and management.
1. Primary angle-closure suspect
2. Narrow anterior chamber angles
3. Angle-closure glaucoma
4. Fellow eye of prior angle-closure attack
5. Pupillary block mechanism
HOW THE PROCEDURE IS PERFORMED
The procedure is performed in the clinic using a focused laser system. First, the doctor applies anesthetic and pressure-lowering eye drops. Next, a special contact lens is placed to guide the laser beam. Then, controlled laser pulses create a tiny iris opening. As a result, fluid flow improves. The treatment usually takes only a few minutes per eye.
PATIENT EXPERIENCE AND RECOVERY
Most patients feel little to no pain because numbing drops are used. During treatment, brief light flashes may be seen. Afterward, mild redness or temporary blur can occur. Nevertheless, most patients return to normal activities within the day. Follow-up visits remain important to confirm pressure control and opening patency.
SAFETY AND CLINICAL VALUE
Nd:YAG Laser Iridotomy has a strong safety record when performed with proper screening and technique. Moreover, it reduces the risk of acute angle-closure attacks, which are ophthalmic emergencies. Early treatment therefore protects the optic nerve and preserves vision.
