Glaucoma surgery reduces pressure on the optic nerve, helping to slow or prevent vision loss due to the disease, according to the Glaucoma Research Foundation. Patients can undergo conventional surgery or laser surgery to treat the condition. After surgery, 70 to 90 percent of patients report a reduction in vision loss.
The Glaucoma Research Foundation also reports that there are five types of laser surgery that treat glaucoma, depending on whether patients suffer from open-angle or narrow-angle glaucoma. These include selective laser trabeculoplasty, argon laser trabeculoplasty, micropulse laser trabeculoplasty, laser peripheral iridotomy and laser cyclophotocoagulation. These all help fluid to drain out of the eye in slightly different locations.
If laser surgery is unsuccessful, the patient may have the option of undergoing conventional surgery. During conventional glaucoma surgery, a flap is cut into the eye to drain out excess fluid.
For those with a mild case of glaucoma, surgery may not be the most ideal option. Instead, a doctor may prescribe special eyedrops to slow down fluid production in the eye and to equalize pressure, according to WebMD. However, WebMD also states that some people may suffer an allergic reaction to the eye drops. As a result, these patients might experience burning, redness or stinging in the eye.
