The goal of Selective Laser Trabeculoplasty (SLT) in open angle glaucoma patients is to help fluids drain out of the eye, which reduces pressure that can cause damage to the delicate optic nerve and possible loss of vision. Unlike Argon Laser Trabeculoplasty (ALT), which can cause damage and scarring to the trabecular meshwork, SLT reduces pressure without this risk. Usually SLT is recommended only after having already been unsuccessfully treated with medications or if one wants to decrease or eliminate the use of eye drops.
During the procedure, the doctor will focus a laser through a special lens. Then at the conclusion of your procedure, you may receive additional eye drops, along with instructions on how to use them.
Serious complications of this type of ophthalmic procedure are extremely rare. However, most patients experience some side effects. Most of these side effects are mild and eventually go away.
