The laser treatment for closed-angle glaucoma, or narrow-angle glaucoma, is laser iridotomy which will open the drainage channels of the eye. During this laser a small hole is created in the peripheral iris (colored part of the eye). This improves the circulation of fluid inside the eye and widens the anterior chamber angle. Fluid which is produced behind the iris has easier access to the eye’s internal drainage system. Sometimes this lowers the intraocular pressure, but that is not the primary goal of laser peripheral iridotomy. The primary goal of the procedure is to lessens the risk of acute angle-closure glaucoma.
After your laser treatment, the eye may feel scratchy or irritated for several hours. This can usually be managed by keeping the eye closed or using over the counter Artificial Tears. After some laser treatments, there are some prescription eye drops that need to be used and your doctor will go over that with you if it is needed. Most patients don’t need anything stronger than Tylenol are able to return to their normal activities the following day.
