Laser treatment offers a safe, effective, and non-incisional way to lower intraocular pressure, serving as a first-line alternative to eye drops or a powerful complement to an existing glaucoma treatment plan.

Precision Treatment, No Surgery Required

For many glaucoma patients, the path to better pressure control doesn't have to go through the operating room. Laser treatment for glaucoma has evolved significantly over the past several decades, and today's procedures offer meaningful, clinically proven pressure reduction with an excellent safety profile, no incisions, and no recovery time. Whether you are newly diagnosed and looking to avoid a lifetime of daily eye drops, or your current medication regimen is no longer providing adequate control, laser treatment may offer a compelling next step.

At Princeton Eye Group, our fellowship-trained glaucoma specialists use selective laser trabeculoplasty in Princeton, Monroe Township, & Somerset, NJ, as an integral part of glaucoma management, helping patients throughout New Jersey protect their vision with the most current and effective tools available.

What Is Glaucoma Laser Treatment?

Glaucoma laser treatment uses precisely focused light energy to improve the drainage of fluid from the eye or prevent dangerous pressure spikes, reducing intraocular pressure without the need for incisions, anesthesia, or a surgical facility. Different laser procedures target different anatomical structures depending on the type of glaucoma being treated and the goal of intervention. The two most commonly performed glaucoma laser procedures are selective laser trabeculoplasty (SLT) and peripheral iridotomy (PI), each addressing a distinct mechanism of elevated intraocular pressure. Both procedures are performed in-office, take only a few minutes, and allow patients to return to normal activities the same day.

The Benefits of Glaucoma Laser Treatment

Effective Pressure Reduction Without Surgery: Laser treatment can achieve clinically meaningful reductions in intraocular pressure without incisions, anesthesia, or an operative setting, making it one of the most accessible interventions in glaucoma care.
A First-Line Alternative to Eye Drops: For many patients with open-angle glaucoma or ocular hypertension, selective laser trabeculoplasty (SLT) can be an excellent first-line treatment and, in some respects, may offer advantages over starting with eye drops. Clinical trials have demonstrated that an SLT-first approach can provide sustained pressure control, reduce or eliminate the need for daily glaucoma medications, and may reduce the need for subsequent glaucoma surgery. For appropriate patients, SLT offers an effective, medication-free approach to glaucoma treatment without the burden of daily eye drops.
Minimal to No Downtime or Recovery Period: Both SLT and peripheral iridotomy are performed in-office in minutes, with no restrictions on normal daily activities following the procedure.
Repeatable Treatment: SLT can be repeated if its pressure-lowering effect diminishes over time, making it a sustainable long-term option within a comprehensive glaucoma management plan.
Preventive Application: Peripheral iridotomy can be performed prophylactically in patients at high risk for angle-closure glaucoma, preventing a potentially sight-threatening pressure spike before it occurs.
Complements Medical and Surgical Treatment: Laser therapy can be used alongside eye drop medications or as a bridge to surgical treatment, offering flexibility in building a personalized, multi-modal glaucoma management plan.

Is Glaucoma Laser Treatment Right for Me?

Glaucoma laser treatment is appropriate for a wide range of patients across the glaucoma spectrum. SLT is particularly well-suited for patients newly diagnosed with open-angle glaucoma who wish to avoid or delay eye drop therapy, patients who are struggling with medication side effects or adherence, and those whose intraocular pressure is not adequately controlled on their current regimen. Peripheral iridotomy is recommended for patients with narrow drainage angles who are at risk for angle-closure glaucoma, as well as those who have experienced an acute angle-closure episode requiring prompt intervention. A comprehensive evaluation at Princeton Eye Group will determine which laser procedure is appropriate for your specific type and stage of glaucoma, and how it fits within your overall treatment plan.

Glaucoma Laser Procedures We Offer

Selective Laser Trabeculoplasty (SLT)

Selective laser trabeculoplasty in New Jersey is a highly effective, non-invasive procedure used to lower intraocular pressure in patients with open-angle glaucoma. SLT uses low-energy laser pulses to selectively target pigmented cells in the trabecular meshwork—the eye's primary drainage tissue—stimulating a biological response that improves the outflow of aqueous humor and lowers eye pressure. Unlike older laser trabeculoplasty techniques, SLT selectively targets only specific cells without causing thermal damage to surrounding tissue, preserving the structural integrity of the drainage angle and allowing the procedure to be safely repeated if needed.

SLT is typically performed as a first-line treatment option or as an adjunct to existing medical therapy. Clinical trials, including the landmark LiGHT study, have demonstrated that SLT is as effective as topical medication as an initial treatment for open-angle glaucoma, with a favorable safety profile and the added benefit of eliminating the daily burden of eye drop adherence for many patients. The procedure takes approximately five minutes, is well tolerated under topical anesthesia, and requires no recovery time.

Peripheral Iridotomy (PI)

Peripheral iridotomy is a laser procedure used to treat or prevent angle-closure glaucoma, a condition in which the drainage angle of the eye becomes blocked by the iris, causing a dangerous and potentially rapid rise in intraocular pressure. During the procedure, a small laser is used to create a tiny opening in the peripheral iris, providing an alternate pathway for aqueous humor to flow from the posterior to the anterior chamber of the eye. This relieves the pressure differential that causes the iris to bow forward and block the drainage angle, preventing acute angle-closure attacks and stabilizing intraocular pressure.

Peripheral iridotomy is recommended both as a treatment for acute angle-closure glaucoma and as a preventive measure in patients whose anatomy places them at elevated risk for an angle-closure episode. It is a brief, in-office procedure performed under topical anesthesia that takes only a few minutes and requires no recovery period. In patients with narrow angles identified during a routine comprehensive eye examination, prophylactic peripheral iridotomy can prevent a sight-threatening emergency before it occurs.

The Glaucoma Laser Treatment Process What to Expect

Comprehensive Glaucoma Evaluation

Your Princeton Eye Group glaucoma specialist will assess your intraocular pressure, drainage angle anatomy, optic nerve health, and visual field to confirm the appropriate laser procedure for your type and stage of glaucoma.

Pre-Treatment Preparation

Eye drops are applied to constrict the pupil or prepare the eye prior to the laser procedure. A special contact lens may be placed on the eye to help focus the laser beam precisely on the target tissue.

The Laser Procedure

The procedure is performed at the slit lamp in the office. Most patients experience only mild pressure or a brief light sensation during treatment. SLT and peripheral iridotomy each take approximately five minutes to complete.

Immediate Post-Treatment

Eye pressure is checked following the procedure to confirm a safe response. Some patients experience mild inflammation or a temporary elevation in pressure in the hours after treatment, which is monitored and managed as needed.

Follow-Up and Monitoring

A follow-up appointment is scheduled within the first few weeks following laser treatment to assess the pressure-lowering response. Your physician will continue to monitor your intraocular pressure, optic nerve, and visual field at regular intervals to evaluate the long-term effectiveness of the procedure.

Your Glaucoma Laser Treatment Results and Recovery

Glaucoma laser treatment requires no meaningful downtime. Most patients return to normal daily activities immediately following the procedure. For SLT, the full pressure-lowering effect typically develops over four to eight weeks following treatment, so patience is important when assessing the outcome. Studies show that SLT achieves clinically significant pressure reduction in the majority of patients, with effects that can last several years before a repeat treatment may be considered.

Peripheral iridotomy produces its structural effect immediately, and follow-up examination confirms that the angle has been successfully opened. As with all glaucoma treatments, ongoing monitoring is essential to ensure that pressure remains controlled and the optic nerve is protected over the long term.

Glaucoma Laser Treatment Frequently Asked Questions

How long does the effect of SLT last?

The pressure-lowering effect of SLT typically lasts between three and five years, though results vary by patient. When the effect begins to diminish, SLT can be safely repeated, making it a sustainable long-term option within a comprehensive glaucoma management plan.

Is SLT as effective as eye drops?

Clinical evidence, including the landmark LiGHT study, has demonstrated that SLT is as effective as first-line topical medication for many patients with open-angle glaucoma, with the added benefit of reducing the need for daily eye drop adherence. Your physician will help determine whether SLT is an appropriate alternative or complement to your current regimen.

Is glaucoma laser treatment painful?

Both SLT and peripheral iridotomy are performed under topical anesthesia and are well tolerated by the vast majority of patients. Most describe a mild pressure sensation or brief flashes of light during the procedure. Significant pain is uncommon.

How soon will I see results after SLT?

The pressure-lowering effect of SLT develops gradually over four to eight weeks following treatment. A follow-up appointment is scheduled within this window to assess the response and determine whether any adjustments to your treatment plan are needed.

Can laser treatment replace my glaucoma eye drops?

For many patients, SLT achieves sufficient pressure reduction to reduce or eliminate the need for daily eye drops. However, results vary by individual, and some patients continue to require medication following laser treatment. Your physician will monitor your response and adjust your regimen accordingly.

What is the difference between SLT and older laser trabeculoplasty procedures?

Older argon laser trabeculoplasty (ALT) uses thermal energy that causes coagulative (or heat) damage to trabecular meshwork tissue, limiting the ability to repeat the procedure. SLT uses lower energy levels that selectively target pigmented cells without damaging surrounding tissue, preserving the ability to repeat the treatment safely if needed.

Who should consider peripheral iridotomy?

Peripheral iridotomy is recommended for patients diagnosed with angle-closure glaucoma, those who have experienced an acute angle-closure episode, and patients with narrow drainage angles identified during a routine eye examination who are at elevated risk for a future attack. Your Princeton Eye Group physician will assess your angle anatomy and advise whether prophylactic treatment is appropriate.
