Selective Laser Trabeculoplasty (SLT) is a revolutionary new laser treatment for glaucoma. The Zion Eye Institute is the first and only office in Southern Utah to have an in-house SLT laser for glaucoma. Unlike previous laser treatments for glaucoma, such as argon laser trabeculoplasty (ALT), the SLT laser does not cause scaring or damage to the drainage structures inside the eye. Clinical studies have shown SLT to be extremely safe, comfortable, and effective for lowering eye pressure associated with glaucoma. Many patients are able to decrease or eliminate the need for glaucoma eye drops after having SLT. The procedure only takes a few minutes to perform in the office and one laser treatment can remain effective for 3-5 years. Because there is no scaring, the treatment can be repeated as necessary.
