This week’s commonly asked questions is all about the lasers involved with glaucoma treatments. Interested? We thought you might because lasers are cool.
What is Direct SLT laser?
Over the last decade, several clinical trials have shown that SLT can be used as a first-line treatment for glaucoma or for when drops are insufficient. Selective laser trabeculoplasty uses a laser to open up the trabecular meshwork (drainage system of the eye), thereby increasing outflow. We are the first in Oregon to have acquired the Voyager direct SLT, which allows the laser to be done without a lens in just a few seconds, with the patient upright, without any sedation. The patient can drive themselves, and there are no activity restrictions. Generally, the effect of SLT lasts 3 to 5 years.
What is G6 laser?
This is an external laser that takes just about 3 minutes to reduce the eye’s production of fluid and modify the ciliary body (the tissue inside the eye that produces fluid). By reducing the fluid production, the eye pressure is reduced. This laser generally needs to be repeated every 1-2 years. This procedure does require IV sedation.
What is laser peripheral iridotomy?
In narrow-angle glaucoma, the drainage angle of the eye is blocked by the iris. A tiny laser hole can be created in a few seconds to release the obstruction.
Drs. Ambati, Mando, and Niespodzany offer glaucoma lasers
