Posterior Capsular Opacification (PCO)
What is Posterior Capsular Opacification (PCO)?
PCO occurs when some epithelial cells that line the lens capsule remain after cataract surgery. These cells can grow and spread across the back of the lens capsule, causing it to become cloudy or opaque. This cell growth is a natural healing response of the eye, but it can interfere with vision if it obscures the path of light through the IOL.

Symptoms of Posterior Capsular Opacification
The symptoms of PCO can develop gradually and may include:
- Blurred, hazy, or cloudy vision
- Glare or halos around lights, especially at night
- Reduced color perception
- Increased sensitivity to light
- Double vision in the affected eye
- Difficulty reading or seeing fine details
If you experience any of these symptoms after cataract surgery, it’s essential to schedule an appointment with the knowledgeable team at The Sight Centre.

What are the Causes of Posterior Capsular Opacification?
Posterior capsular opacification (PCO) is a condition that can occur after cataract surgery. Several factors may increase the risk of developing PCO.
Younger age at the time of cataract surgery is a risk factor for PCO. Certain types of cataracts, such as posterior subcapsular cataracts, are also associated with a higher risk of developing PCO.
Pre-existing eye conditions, including uveitis (inflammation of the eye) and diabetic retinopathy, can increase the likelihood of PCO. The type of intraocular lens (IOL) used during cataract surgery may also influence the risk of developing PCO.
