Selective Laser Trabeculoplasty

Selective laser trabeculoplasty (or SLT) is a simple laser procedure for
glaucoma that can be performed in the eye clinic.

It is used to lower the intraocular pressure in suitable patients. It can be used as
an alternative to regular long-term use of eye drops or as an adjunct when eye
drops are not lowering the eye pressure enough.

What is SLT and how does it work?

In SLT, micro-pulses of laser energy is applied to the drainage tissue inside the eye. This laser energy is specifically designed to target the pigment cells in the drainage tissue, and causes a biological reaction and healing response in the tissue. Th ultimately improves the passage of fluid through the drain and lowers the intraocular pressure. However it may take 1-3 months for the desired effect to fully appear. 

What happens during the procedure?

The laser is delivered via a microscope similar to those used for eye examination. Prior to the treatment, several eye drops are instilled to prepare the eye for the procedure. During the procedure, the laser will appear as pulses of light applied to the eye via a special lens that rests on the eye. The entire procedure takes less than 5 minutes to perform, and is generally painless. Mild aching sensation may seldom occur after the procedure, but invariably resolves within 24 hours.
