An in-office laser treatment may be used to treat glaucoma. One of the types of laser treatment, a Peripheral Iridotomy, is used to treat narrow/closed angle glaucoma. Another type of laser treatment, a Selective Laser Trabeculoplasty (SLT), is used to treat open angle glaucoma. During an SLT, a laser is directed into the trabecular meshwork, the drain of your eye. The effects of this laser treatment develops over several weeks and generally lasts 1.5 years (although it can last longer than this as well or it may not be effective at all). The response rate is approximately 80%.

If the pressure is not controlled by drops or laser, or in some emergency cases, your doctor may recommend glaucoma surgery. The goal with outpatient surgery is to essentially create a new drain for the eye, which fluid can drain through, thereby reducing the eye pressure.
