The risks of laser surgery to treat glaucoma include an temporary increase in intraocular pressure, according to the Glaucoma Research Foundation. On the other hand, the intraocular pressure may drop to the point where the eye cannot hold onto its shape, and its functioning is impaired.
Taking glaucoma medication both before and after the surgery mitigates these risks, claims the Glaucoma Research Foundation. Another risk of laser glaucoma surgery is the development of cataracts.
Several types of laser surgery are available to treat glaucoma, says the Glaucoma Research Foundation. They include selective laser trabeculoplasty, argon laser trabeculoplasty, micropulse laser trabeculoplasty, laser peripheral iridotomy and laser cyclophotocoagulation.
