YAG laser surgery, also known as Nd:YAG laser posterior capsulotomy, is performed to correct the clouding on a lens after cataract surgery, says WebMD. In some cases the clouded lens can lead to more vision loss experienced from the original cataract several months or years after cataract surgery.Continue Reading
Before the corrective outpatient procedure, the surgeon applies anesthetic eye drops to the patient's eyes to ensure that he doesn't feel pain, notes WebMD. The Nd:YAG laser is then used to create a hole in the back lining of the clouded lens capsule, which allows light to pierce through the membrane to the back of the eye. A couple of hours after the surgery the patient has his intraocular pressure checked.
Risks associated with the procedure include short-term pressure on the interior of the eye, detachment of the rear nerve layer in the eye, swelling, bleeding, and damage to the intraocular lens, says WebMD. Extra pressure can be handled with eye drops. Since there is no way of telling which individuals may experience clouding, the procedure cannot be done as a preventative measure.
Once the YAG laser procedure is complete, the patient should not feel any pain. WebMD recommends that individuals consider the risks and benefits of the surgery before deciding to have it done.Learn more about Diagnostics & Imaging
