Can vision deteriorate after-cataract surgery?
Sometimes blurry vision is caused by PCO, a fairly common complication that can occur weeks, months or (more frequently) years after cataract surgery. It happens when the lens capsule, the membrane that holds your new, intraocular lens in place, becomes hazy or wrinkled and starts to cloud vision.
