During cataract surgery, a circular opening is made in the anterior capsule, but the entire capsule is not removed. Part of the anterior capsule is left to support the intraocular lens. The back portion of the capsule is usually preserved as well. This remaining structure keeps the new lens stable.

Only the central portion of the anterior capsule is opened. This approach supports long-term clarity and lens stability.
No, only the central section is opened.
It provides support for the implanted lens.
Yes, it remains unless complications require removal.
Yes, some people develop posterior capsule opacification.
During cataract surgery, the front portion of the lens capsule (anterior capsule) is opened (capsulorhexis) to remove the cloudy lens contents. The posterior capsule is usually left intact to support the intraocular lens implant.
The posterior capsule provides support for the artificial lens and acts as a barrier between the anterior and posterior segments. Keeping it intact helps prevent complications.
Over time, the posterior capsule can become cloudy, causing vision to blur. A quick laser procedure called YAG capsulotomy can create an opening in the capsule to restore clear vision.
