Selective Laser Trabeculoplasty (SLT)

SLT (Selective Laser Trabeculoplasty) is a safe and simple in-office laser treatment that effectively reduces the pressure in the eye for most patients with glaucoma. The SLT mechanism of effect does not rely on medicines, instead, it uses an advanced laser system to target only specific cells of the eye—those containing melanin, a natural pigment. This allows for only these cells to be affected, leaving surrounding tissue intact. As a result, your body’s own healing response helps lower the pressure in your eye.

Argon Laser Trabeculoplasty (ALT)

ALT is also an in-office laser therapy and has a helpful effect on eye pressure that is similar to that of SLT, but uses longer pulses that non-selectively target cells. ALT is much more likely to result in unnecessary damage and scarring to surrounding internal eye structures, limiting treatment repeatability options for maintaining eye pressure control and vision preservation.
