When we do cataract surgery we leave the membrane that used to surround the old lens in place. This membrane is clear like cellophane and acts as a container for the new implant. Months to years after cataract surgery, this membrane can get cloudy and blur vision. This problem is easily corrected with a 15 second nonpainful procedure by making an opening in the membrane with a YAG laser. This is called a YAG capsulotomy.
