During cataract surgery a new lens is placed within the capsular bag behind the iris. The rear wall of this bag is a thin membrane called the posterior capsule.
With time the posterior capsule can become cloudy causing blurry vision, glare and haze. This opacity is called a Posterior Capsule Opacification (PCO).
PCO is treatable and can be cleared using a YAG laser. This procedure takes just a few minutes, is painless, does not require a hospital admission or anaesthetic and the membrane almost never grows back again.
