For the treatment of primary open angle glaucoma your eye doctor may recommend an SLT, or a Selective Laser Trabeculoplasty. SLT is a form of laser surgery that is used to lower intraocular pressure (IOP) in glaucoma. SLT may be a good alternative for those who have not been treated successfully with eye drops alone. Some studies suggest that the SLT is effective around 80 percent of the time and that it lowers IOP by 20 to 25 percent.   Laser energy is applied to the drainage tissue in the eye.  This starts a chemical and biological change in the tissue that results in better drainage of fluid through the drain and out of the eye. This eventually results in lowering the pressure.  It could take up to three months for results to appear, but will generally last anywhere from one to three years. SLT procedure can be repeated, but the second treatment may not be effective as the first and may not last as long.  If the initial SLT is not successful, repeat treatment is not likely to be effective.   Some patients can control their IOP with laser treatment alone. Others require additional lowering of their pressure and therefore may need to use glaucoma medicine as well.  It’s best to consult with your eye doctor to determine if an SLT procedure will work for you.
