Selective Laser Trabeculoplasty (SLT)

What is laser selective laser trabeculoplasty (SLT)?

Selective laser trabeculoplasty (SLT) is when laser is used to lower eye pressure in certain types of glaucoma or ocular hypertension (high eye pressure). SLT is easy to perform and it is tolerated well by patients. It is highly effective in lowering the eye pressure and its effect lasts for years. In recent years, many ophthalmologists offer SLT instead of eye drops as the initial treatment for ocular hypertension and certain types of glaucoma. 

What conditions are treated by selective laser trabeculoplasty (SLT)?

As mentioned above, selective laser trabeculoplasty (SLT) is used to treat ocular hypertension (high eye pressure) or certain types of glaucoma

How is selective laser trabeculoplasty (SLT) done?

Selective laser trabeculoplasty (SLT) is performed in the office. The patient sits at the laser machine. Using a special lens, the ophthalmologist applies laser to the part of the eye that drains its fluid. The procedure lasts a few minutes and the patient feels minimal to no pain. SLT can decrease eye pressure by 25%-30% and its effect lasts 3-5 years. 

What are some side effects and risks of selective laser trabeculoplasty (SLT)?

Selective laser trabeculoplasty (SLT) is a generally a safe procedure. Occasionally there is a rise in eye pressure immediately after the procedure which can be prevented by eye drops.
