Selective Laser Trabeculoplasty (SLT) is AN ADVANCED TYPE OF LASER TREATMENT to manage patients with open-angel glaucoma. Instead of generally burning tissue as in ALT, SLT selectively stimulates or changes only specific pigmented cells to activate increased fluid drainage. Both SLT and ALT produce equivalent drops in IOP, however the more gentler SLT procedure does not have the associated damage to other tissues and adverse scarring effects. For this reason, where ALT is limited, SLT may potentially be repeated. SLT has also been found to be effective when ALT and other forms of medical treatment have failed.
Benefits of SLT
•SLT results in a biological response that increases aqueous drainage, and reduces intraocular pressure without burning tissue.
•No adverse reaction from medications.
•No adverse scarring of Trabecular Meshwork.
•May reduce the need for lifelong use of expensive eye drops and other medications
•May reduce or eliminate the trouble of always having to take glaucoma medications.
How is SLT performed?
SLT is usually performed in the office and only takes about 15-20 minutes. Prior to the procedure, eye drops will be given to prepare the eye for treatment. The laser applications are made through a special microscope, similar to the one used for eye examinations. About 2 hours of office time should be planned so the IOP can be checked after the eye is treated.
