What is posterior lens capsule opacification (PCO)?

Posterior capsule opacification (PCO) is a fairly common complication of cataract surgery. Sometimes you can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place.

If this happens you may need to have laser treatment to make vision clear again. This procedure is called Nd:YAG laser capsulotomy.

More information can be found on our posterior lens capsule opacification web page.

We also have a posterior lens capsule opacification factsheet:
