Selective laser trabeculoplasty

Laser trabeculoplasty uses a very focused beam of light to treat thedrainage angle of the eye. This surgery makes it easier for fluid to flow out of the front part of the eye, decreasing pressure in the eye. There are two types of laser trabeculoplasty:Argon laser trabeculoplasty (ALT) uses a laser to open up the drainage angle of the eye.Selective laser trabeculoplasty (SLT) uses a lower-level laser to open the drainage angle of the eye.
