Introduction to SLT

SLT angle Selective laser trabeculoplasty (SLT) is a safe and effective treatment modality for lowering the intraocular pressure in patients with early, mild and moderate glaucoma.

This technique uses a Q-Switched, frequency doubled Nd: YAG laser with a wavelength of 532 nm. The impact spot size and duration of the pulses are fixed, respectively 400 μm and 4 ns.

SLT achieves its results by selective absorption of energy in the trabecular pigmented cells, sparing adjacent tissues from thermal damage, with minimal tissue alteration following treatment.
