Why is a posterior capsulotomy necessary?
Cataract surgery removes a cataract (the cloudy lens causing blurred vision) from its cellophane-like lining called the lens capsule. An artificial lens called an intraocular lens, or IOL) is then inserted into the capsule to replace the natural lens. The lens capsule may become cloudy as the eye heals after the cataract surgery causing your vision to become blurry. This usually happens six months to a few years after cataract surgery.
What happens during posterior capsulotomy?
A special laser is targeted at the back of the capsule and makes a small opening. The technique is painless and only takes a few minutes Anesthesia, if necessary, is applied using eye drops. You should notice improved vision quickly, if there are no other problems with your eye. Unless your doctor advises otherwise, normal activities can usually be resumed immediately.
Are there any risks involved?
As with any surgical procedure, rare complications can occur, including:
  • Detachment of the retina (symptoms of a retinal detachment may include a curtain or cobweb that goes across your vision, or the sudden appearance of many floaters in your vision)
  • Loss or decrease in vision
  • Increased intraocular pressure
  • Dislocation of the IOL through the posterior capsule opening.
  • Inflammation in the eye, possibly requiring treatment with steroid eye drops.

Be sure to discuss potential complications with your doctor before surgery.
