Problems after surgery are rare, but they can occur. These problems can include infection, bleeding, inflammation such as pain, redness, swelling, loss of vision, double vision, and high or low eye pressure. With prompt medical attention, these problems can usually be treated successfully.Sometimes the eye tissue that encloses the IOL becomes cloudy and may blur vision. This condition is called an after-cataract. An after-cataract can develop months or years after cataract surgery.An after-cataract is treated with a laser. The doctor uses a laser to make a tiny hole in the eye tissue behind the lens to let light pass through. This outpatient procedure is called a YAG laser capsulotomy. It is painless and rarely results in increased eye pressure or other eye problems. As a precaution, the doctor may prescribe eyedrops to lower eye pressure before or after the procedure.
