Selective Laser Trabeculoplasty (SLT)


For the treatment of primary open-angle glaucoma (POAG) and ocular hypertension.

SLT uses a laser that works at very low levels. It treats specific cells "selectively,” leaving untreated portions of the trabecular meshwork intact. For this reason, SLT may be safely repeated.  The laser pulses do not burn or change your prescription.  SLT only cleans the outflow channels to reduce eye pressure.

SLT may be an alternative for those who have been treated unsuccessfully with ALT or pressure-lowering drops, or as first-time therapy in lieu of drops.

How SLT Works

Selective Laser Therapy (SLT) is an advancement over other lasers that have been used in the treatment of open-angle glaucoma for more than two decades.

Selective Laser Therapy

SLT works by using laser light to stimulate the body’s own healing response to lower your eye pressure. Using a special wavelength and energy, the laser affects only pigmented (melanin containing) cells of your eye unlike ALT which permanently damages and scars the eye. SLT improves the flow of fluid in the eye, which in turn lowers your eye pressure.

SLT Pre-Procedure

SLT 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 applied through a regular physician microscope (slit lamp), similar to the one used for eye examinations.

SLT Post-Procedure

Your eye pressure may drop as quickly as in a day after having SLT performed. The doctor may treat the eye with anti-inflammatory eye drops that will be continued for a few days after the procedure. Patients have no limitations after their procedure and are able to drive home. Patients will be scheduled for a follow up appointment to allow the physician to evaluate the results.

SLT is a very effective treatment and can be used in many different types and stages of glaucoma. Ask your physician for SLT by name.

Who Can Be Treated?

SLT Therapy is a treatment option for most patients. Due to the nondestructive nature of SLT Therapy unlike traditional laser therapy, SLT can be used for the following conditions:

  • Primary Open Angle Glaucoma
  • Ocular Hyper Tension
  • Normal Tension Glaucoma
  • Juvenile Glaucoma
  • Aphakic Glaucoma
  • Pigmentary Glaucoma

SLT Therapy is a treatment option for most glaucoma patients. As well most patients prefer to be treated with SLT-Therapy as a first treatment choice when first diagnosed with glaucoma.


Lumenis SLT is typically covered by Medicare and may reduce or eliminate the need to take glaucoma medications.


Patient compliance refers to how well patients are able to follow their prescription schedules, as directed by their doctors. At Lumenis, we understand that the pressures and demands of today’s busy lifestyles make it challenging to follow strict prescription schedules. However, noncompliance is very serious because it can cause large changes in eye pressure, which may increase the speed of vision loss from glaucoma and lead to blindness. Noncompliance can also lead doctors to overmedicate or misdiagnose treatment effectiveness.

SLT does not require compliance with a prescription schedule and may reduce or eliminate the need to take glaucoma medications.
