Capsule of lens - Wikipedia
The lens capsule is a component of the globe of the eye. It is a clear elastic basement membrane similar in composition to other basement membranes in the body. The capsule is a very thick basement membrane and the thickness varies in different areas on the lens surface and with the age of the animal. It is composed of various types of fibers such as collagen IV, laminin, etc. and thes…
Anatomy
The lens capsule is a transparent membrane that surrounds the entire lens. The capsule is thinnest at the posterior pole with approximate thickness of 3.5μm. Average thickness at the equator is 7μm. Anterior pole thic… 展开
Function
The capsule helps give the lens its more spherical shape in aquatic vertebrates such as fish and more ellipsoidal shape in land based vertebrates such as sheep. In humans the lens ellipsoid becomes more flattened with ag… 展开

How does the eye capsule work?
It is composed of various types of fibers such as collagen IV, laminin, etc. and these help it stay under constant tension. The capsule is attached to the surrounding eye by numerous suspensory ligaments and in turn suspends the rest of the lens in an appropriate position. As the lens grows throughout life so must the capsule.

How does a capsule shape affect the eye?
Due to the shape of the capsule, the lens naturally tends towards a rounder or more globular configuration, a shape it must assume for the eye to focus at a near distance. Tension on the capsule is varied to allow the lens to subtly change shape to allow the eye to focus in a process called accommodation.

What is a capsule-intraocular lens (IOL) complex?
During early phase after cataract surgery, the capsule-intraocular lens (IOL) complex experiences a significant apposition process which is crucial for IOL stability, refractive outcomes, and the development of posterior capsular opacification (PCO) [1, 2, 3, 4, 5, 6]. Initially, IOL locates in a relatively large and loose capsular bag.

How long does a lens capsule stay intact after cataract extraction?
In the human eye, the lens capsule remains intact for decades following removal of lens cells during extracapsular cataract extraction, allowing for the insertion and stability of artificial intraocular lenses (IOLs) and the emerging designs of accommodating IOLs (Bruck, 1993).

Does a capsule protect the lens from bacterial infections?
The capsule has been proposed to be a barrier protecting the lens from bacterial and most viral infections (Beyer et al., 1984; Cotlier et al., 1968; Karkinen-Jaaskelainen et al., 1975) in addition to conferring immune privilege to the lens (Coulombre, 1979).
