The correct spelling of the term "Crystalline Lens Capsules" is pronounced as /krɪˈstælaɪn lɛnz ˈkæpsjʊlz/. The word "crystalline" refers to something resembling crystal in clarity, while "lens" refers to a curved transparent material, usually glass, that refracts light to form an image. "Capsules" denotes a small container that holds something inside. When combined, these terms refer to the small, crystal-clear containers present on the outer layer of the eye's natural lenses.
Crystalline lens capsules are a term used in ophthalmology to refer to the clear and elastic structure that encapsulates the crystalline lens within the eye. The crystalline lens, located behind the iris, is an important part of the eye responsible for focusing light onto the retina, allowing for clear vision.
The crystalline lens capsule is a transparent outer covering that completely surrounds the crystalline lens. It is composed of thin layers of collagen fibers, which provide strength and flexibility to the capsule. This elasticity enables the lens to change shape and adjust its focusing power to see objects at various distances.
The primary function of the crystalline lens capsules is to maintain the shape and position of the lens within the eye. It acts as a barrier, protecting the delicate inner structure of the lens from external damage. Additionally, the capsules also provide attachment sites for the suspensory ligament, a system of fibers that hold the lens in place.
As a person ages, the crystalline lens undergoes natural changes, leading to the development of opacities or cloudiness within the lens. This condition is commonly known as cataracts. In cataract surgery, the cloudy lens is removed while leaving the intact crystalline lens capsules in place. An artificial intraocular lens is then inserted into the empty capsular bag, providing vision correction. The presence of the crystalline lens capsules is crucial during this surgical procedure as they provide support and stability to the new lens.
