Posterior capsule opacification is a frequent cause of blurred vision after otherwise successful cataract surgery and occurs when the capsule behind the implant becomes hazy.
Symptoms patients may notice
Vision can feel as though the cataract has returned, even though the artificial lens itself remains clear. Everyday tasks like reading, driving, or recognising faces may become more difficult again.
- Blurred or foggy vision that slowly worsens
- Increased glare from sunlight or headlights
- Halos or starbursts around bright lights
- Colours appearing washed out compared with immediately after surgery
Diagnosis and reassurance
An eye specialist can see posterior capsule opacification by examining the back of the lens implant with a microscope. The condition is very common and treatable, so patients are reassured that a simple laser procedure can usually restore clarity.
- YAG laser capsulotomy creates a clear opening in the cloudy capsule
- The treatment is done in the outpatient clinic, not in an operating theatre
- Vision typically improves quickly with minimal downtime
- Contact the clinic promptly if new floaters, flashes, or a shadow appear afterwards
