Glaucoma Laser Surgery
Selective laser trabeculoplasty (SLT) is often used to treat open angle glaucoma. During SLT surgery, a low level of energy targets specific cells in the mesh-like drainage channels using very short applications of light. This treatment is very safe, and can be used as a first line treatment even before glaucoma drops if a patient is a candidate. The laser can also be repeated in the future if the intraocular pressure rises. Laser iridotomy is recommended for treating people with closed-angle glaucoma and those with very narrow drainage angles. A laser creates a small hole about the size of a pinhead through the top part of the iris to improve the flow of aqueous fluid to the drainage angle.
