Glaucoma is a leading cause of vision loss, but today’s advanced treatments make managing it more effective than ever. Two common laser options are Selective Laser Trabeculoplasty (SLT) and YAG laser treatment, each designed for different forms of glaucoma. At The Eye Center of Virginia, our experienced eye doctors in Williamsburg, VA help patients understand which option best supports long-term eye health.

What Is SLT?

SLT is typically used for open-angle glaucoma. It applies low-energy laser pulses to the eye’s drainage system to improve fluid outflow and lower intraocular pressure (IOP). Many patients choose SLT because it reduces or eliminates the need for daily eye drops, offers quick recovery, and can be repeated if pressure rises again.

What Is YAG Laser Treatment?

YAG laser treatment, most commonly performed as a YAG peripheral iridotomy (PI), is used for narrow-angle or angle-closure glaucoma. When the drainage angle becomes too narrow, fluid cannot drain properly. A YAG PI creates a small opening in the iris to restore normal fluid flow and reduce the risk of sudden pressure spikes. This procedure is often preventive and also has a short recovery period.

Which Treatment Is Better?

There is no universal “best” choice - each treatment is designed for very different types of glaucoma and unique eye anatomy. SLT is often ideal for patients with open-angle glaucoma, especially those looking for long-term pressure management without relying heavily on daily medications. Because SLT improves the eye’s natural drainage function, it can be a strong first-line treatment or a supportive therapy when drops alone are not enough.

YAG laser treatment, on the other hand, is typically recommended for patients with narrow angles or those at higher risk for angle-closure glaucoma, a condition that can lead to sudden and dangerous spikes in eye pressure. By creating a small opening in the iris, a YAG peripheral iridotomy helps prevent blockage, protects the optic nerve, and reduces the likelihood of acute glaucoma attacks.

While these procedures serve different purposes, both are quick, minimally invasive, and performed right in the office, allowing patients to return to normal activities soon after treatment. Following a detailed eye exam and imaging of your drainage angle, your doctor will determine which laser procedure is safest, most effective, and best suited to preserving your long-term vision.
