LENS CAPSULE Meaning and
Definition
-
Lens capsule is a transparent, elastic, and fibrous membrane that surrounds and encloses the lens of the eye. It is a critical anatomical structure responsible for the support, protection, and maintenance of the lens's shape, position, and clarity. The lens capsule consists of two layers: the anterior and posterior capsules.
The anterior capsule is located on the front surface of the lens and is in direct contact with the aqueous humor, the clear fluid filling the anterior chamber of the eye. This layer is attached to the circular perimeter of the lens and helps maintain the lens in position within the eye.
The posterior capsule, on the other hand, is the inner layer of the lens capsule and is located at the backside of the lens. It separates the lens from the vitreous humor, the gel-like substance that fills the posterior chamber of the eye. The posterior capsule provides mechanical support and prevents the lens from coming into contact with the vitreous humor.
Functionally, the lens capsule acts as a protective barrier, shielding the delicate lens tissues from external damage and maintaining its structural integrity. It also serves as a scaffold for the attachment of lens fibers, which are elongated cells responsible for the lens's transparency and flexibility. In addition, the lens capsule plays a crucial role in accommodating changes in the lens shape during the process of focusing on objects at various distances, allowing for clear vision.
