What is cataract surgery for restoring eye vision?
Cataract surgery is an operation used to treat cataracts when changes in the lens of the eye cause blurry, cloudy, or hazy vision. Cataracts occur when changes in the lens of the eye cause it to become less transparent. The lens is a crystal structure that is directly behind your pupil, and this is a black circle in the center of your eye. When light enters your eye, it passes through a transparent layer of tissue in the front of the eye (the cornea) and the lens that focuses it on the photosensitive layer of cells in the back of the eye (the retina).
Cataract is also called clouding of the lens.
Like everything in our body, the ocular lens is subject to the aging process, which also leads to its clouding. Most often, this disease is due to age, therefore, it is also called senile cataract. Age cataract occurs usually in people older than 60 years. Only in rare cases, it is congenital.In the beginning, the disease is perceived as a thin veil on the eyes, which eventually becomes denser. Often cataracts become more sensitive to light. If the clouding of the lens progresses and visual acuity deteriorates noticeably, cataract surgery is needed.
Cataract surgery is one of the most common surgical interventions in general. This is the only option for the treatment of progressive cataracts (clouding of the lens). In the process of the cataract surgery, the clouded lens is removed and replaced by an artificial lens. Throughout the world, cataracts are the most common cause of blindness because, without proper treatment, this disease leads to loss of vision. If the treatment is carried out through surgery, the hopes for success are very high. Surgical cataract treatment usually provides a complete recovery of vision.
