What is a cataract?
Partial or total opacity of the lens caused by various reasons is called cataract. Cataract mainly manifests as decreased vision and blurred vision, but vision is not the only criterion for clinical diagnosis of cataract.
The so-called black eyeball that we can see in front of the eyeball is called cornea. The iris and pupil can be seen behind the cornea, and the lens behind can be seen through the pupil. The suspensory ligament of the lens is suspended on the ciliary body, located in front of the eyeball, and consists of lens capsule, cortex and nucleus. Its function is similar to the lens of a camera, which helps to focus accurately and enables us to see far and near objects clearly. If the lens is cloudy, it is a cataract. There are many reasons for lens opacity, including age, ultraviolet rays, malnutrition, diabetes and other metabolic diseases, drugs and poisoning, as well as other eye diseases such as uveitis, retinitis pigmentosa, retinal detachment, advanced glaucoma, intraocular tumors, low intraocular pressure, high myopia and genetic and congenital factors. Among them, the most common reason is age. With the increase of age, the natural aging of the lens leads to the turbidity and whitening of the lens.
