MicroPulse Laser Trabeculoplasty (MLT)

Micropulse laser trabeculoplasty (MLT) is a new, non-burning laser therapy for reducing intraocular pressure in eyes with primary open-angle glaucoma and ocular hypertension. This treatment opens the drainage channel of the eye called the trabecular meshwork by targeting specific pigment cells of the eye and without producing clinically observable heat effects or scarring.

MicroPulse Laser Trabeculoplasty (MLT) can provide the same IOP-lower effects as older laser procedures termed ALT, or SLT, with less energy and inflammation. MLT improves upon both of the other laser procedures. The eyes remain quiet with minimal postoperative inflammation. Most patients will not require anti-inflammatory drugs after MLT.

The MLT laser is even more comfortable than the SLT, and if need be, can be repeated. MLT employs a series of low power pulses for a short duration, or “micropulse” followed by a pause in laser delivery.

Some of the Benefits of MLT

• Safe: MLT is not associated with systemic side effects or the compliance and cost issues of medications.
• Selective: MLT targets only specific cells, leaving the surrounding tissue intact.
• Smart: MLT stimulates the body's natural mechanisms to enhance outflow of the fluid in your eye.
• Sensible: MLT therapy is reimbursed by Medicare and many other insurance providers, which minimizes your out-of-pocket expenses.

How MLT Works

MicroPulse Laser Trabeculoplasty (MLT) is an advancement over other lasers that have been used safely and effectively in the treatment of open-angle glaucoma for more than two decades.
MLT works by using laser light to stimulate the body's own healing response to lower your eye pressure. Using a special wave-length and energy, the laser affects only pigmented (melanin containing) cells of your eye. MLT improves the flow of fluid in the eye, which in turn lowers your eye pressure.

How MLT is performed

MLT is usually performed in the physician's office and only takes a few minutes. Prior to the procedure, eye drops will be given to prepare the eye for treatment. The laser applications are made through a special microscope, similar to the one used for eye examinations.

What to expect after MLT treatment

Most patients have no irritation after the procedure but some may feel some mild foreign body sensation similar to an eyelash in the eye. The effect of the MLT occurs gradually over 4 to 5 weeks. Some patients may actually have an increase in eye pressure for the first week or so after the procedure.

The doctor may treat the eye with anti-inflammatory eye drops that will be continued after the procedure. Most likely, you will have to return for follow-up visits.

Frequently Asked Questions

What are the side effects of MLT?
Unlike some glaucoma medications, there are no incidences of allergy or systemic side-effects with MLT. Complications are minimal but may include inflammation, temporary increase in eye pressure, blurred vision, headache, iritis, corneal edema, corneal lesion, conjunctivitis, or eye pain. For more information about MLT and how it may benefit you, contact New Vision Eye Center.

Will I feel anything with the laser treatment?
Generally, the laser treatment does not cause pain. However, studies show some patients experience a mild pressure sensation during treatment from the lens used to aim the laser. You may see a green flash of light, and should feel absolutely nothing from the laser. The lens used on your eye may cause some redness or irritation.
