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. Weeks to years after cataract surgery, the capsule may become cloudy or wrinkled and cause blurred vision. A posterior capsulotomy is a simple laser procedure that makes an opening in the back or posterior, part of the capsule to restore your normal vision.
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. It is performed on an outpatient basis, often in your ophthalmologist’s office. Anesthesia, if necessary, is applied using eyedrops. 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); 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 ophthalmologist before surgery
