The standard method to correct secondary cataracts is YAG laser capsulotomy, not glasses, according to the American Optometric Association. This is a type of laser surgery sometimes performed on the membrane that remains after traditional cataract surgery. As the membrane turns cloudy, vision worsens.
About half of the people who have cataract surgery develop secondary cataracts. During YAG laser capsulotomy, a small hole is made in the affected membrane so light is able to pass through it. This is typically a simple five-minute outpatient procedure. The patient remains in the doctor's office for another hour while eye pressure is monitored. Results are usually immediate, though some patients slowly improve over the course of many days.
