Question: How are PCO cataracts removed?

Answer: Poster capsular opacifications are “after cataracts” that form in the remaining posterior capular bag after a cataract surgery. They are quite common, and treated by using a YAG laser to pop a hole through the capsule, thus clearing the visual axis.

YAG capsulotomy is relatively easy to perform, however, it is not without risks. The laser creates a shockwave in the eye and this energy can induce a retinal detachment.
