Posterior capsule opacification (PCO)
Posterior capsule opacification (PCO) is a complication that can occur after cataract surgery, causing the lens capsule to thicken and become cloudy. PCO can be caused by the proliferation and migration of residual lens epithelial cells. This can lead to blurred vision, glare from lights, and hazy vision.
Secondary cataract
PCO is also known as a secondary cataract. It’s a common complication that can occur months or years after the surgery.
Yag laser surgery
PCO can be treated with a quick, painless, outpatient laser procedure called YAG (Yttrium Aluminium Garnet) laser surgery.
Some factors that may increase the risk of PCO include:
- Exogenous hyaluronic acid (HA), a component of some viscoelastic substances used during cataract surgery
- Short-term exposure to TGF-β
You should see an eye doctor immediately if you begin having blurred or misty vision or glare when you look at lights and you have had cataract or lens replacement surgery in the past.
