How does SLT work?
Laser energy is applied to the trabecular meshwork. The trabecular meshwork is located in the front of the eye and is the natural drain for fluid. SLT stimulates the trabecular meshwork to increase the amount of fluid drained from within the eye, which lowers eye pressure. It may take up to 2 months for the laser to take its full effect.
Who needs SLT?
Patients with open-angle glaucoma who need improvement in eye pressure control. This can be used alone or as an addition to eye drops.
What are the benefits?
On average, SLT can lower the eye pressure by about 20-30%. The laser is effective in lowering eye pressure in about 80% of patients. The laser effect wears off after several years, but the trabecular meshwork can be stimulated again with repeat laser. SLT does not affect the success rates or the eligibility of getting other medical or surgical treatments.
What are the risks?
Compared to many other treatments for glaucoma, including eye drops, other laser treatments and surgery, SLT has few side effects. Inflammation is possible after the laser but it is not common. You may be prescribed anti-inflammatory drops on an individual basis. There is a small risk of temporary high eye pressures shortly following the laser treatment. This is usually controlled with glaucoma medications.
Will SLT cure my Glaucoma?
The simple answer is “No”. Glaucoma is a chronic disease that requires constant monitoring and treatment. The SLT procedure will help to lower your eye pressure. However, it will not reverse any loss of vision that has already occurred.
