Posterior Capsular Opacification
Often called a "secondary cataract," this is a clouding of the lens capsule that can develop months or years after cataract surgery -- and is treated quickly with a simple laser procedure.

If your vision was clear after surgery but has gradually become hazy again, this is the most likely explanation -- not a new cataract, since the natural lens has already been removed.
Noticing blurred vision returning?
Blurring, glare, or haze that feels similar to your original cataract symptoms but appears after a successful surgery usually points to this condition, and it's straightforward to confirm and treat.
What Is It?
Posterior capsular opacification occurs when the thin membrane (capsule) left behind after cataract surgery — which holds the new artificial lens in place — gradually becomes cloudy. This is not a new cataract, since the original clouded lens was already removed; it’s a separate, very common change that can occur months to years after otherwise successful surgery.
The good news is that it’s treated with a quick, painless YAG laser capsulotomy performed in a single outpatient visit, with no incision and no recovery time. Most patients notice clearer vision within a day.
Risk Factors
- Time elapsed since cataract surgery (more common with longer intervals)
- Younger age at the time of cataract surgery
- Certain pre-existing eye conditions
Symptoms
- Gradual blurring of vision after previously clear vision post-surgery
- Increased glare or haze, especially in bright light
- Difficulty with night driving
- A sense that vision has "returned" to how it was before cataract surgery
Treatment
- YAG Laser Capsulotomy: A quick, painless outpatient laser procedure that clears the cloudy capsule, typically restoring vision within a day with no incision required.
