What happens during cataract surgery?

cataracts are a common problem of eye, which suffers from almost all middle -aged adults, and may occur in younger people due to injury or genetic predisposition. Cataracts cause the outer lens of the eye on the clouds, rendering vision of cloudy or fogged. During the surgery of cataract, the eye surgeon removes the cloudy lens of the eye and replaces it with a synthetic implant not nitroocular lenses. Removal during cataract surgery is achieved either by breaking the lens and suction from the eyeball, or I cut into the eye and lift the damaged lens in one piece.

cloud effects of cataract cannot be reversed. Once the eye lens loses the focus, this focus is gone forever and usually deteriorates over time. Regulation glasses can improve the purity of vision suffering from cataract, but usually cannot completely eliminate the fog. The most effective treatment of cataract is to actually remove the deteriorated lens of the eye. This is in the surgery of cataract.

Not all cataracts are sufficiently serious,to guarantee surgery. The ophthalmologist usually recommends cataract surgery when cataracts in one or both eyes deeply affect the patient's quality of life. Cataracts are specific to the eyes, which means they can occur in one eye, but not the other. In older adults, especially those over 60, it is common for cataracts to be in both eyes.

cataract surgery, like most eye operations, is usually an out-of-art procedure. The operation itself is not lengthy, often not more than 10 to 20 minutes. Recovery is what takes the longest.

Cataract operation begins with sitting eyes, usually through eye drops or small injections to the area directly surrounding the eye socket. The eyelids are sterilized and the face is usually covered with a protective mask or sterile substance. The surgeon then removes the damaged eye lens with one of the two methods.

the first method known as FAKoemulsification is when the eye surgeon puts a small probe into the lens, usually by making a small cut in the cornea sitting on the surface of the eye. The probe emits ultrasonic waves that decompose the lens. The probe then sucks all pieces of the lens.

In the second method, known as the extracapsular method, the surgeon of cataracts will make a larger corneal cut, allowing the lens to be removed in one piece. Once the lens is removed by one method, the surgeon attaches the synthetic lens known as the intraocular lens (IOL). IOL is usually a pure plastic lens designed to imitate the shape of the damaged original. After the operation, the cornea will heal above the IOL, making it a permanent part of the eye. Unlike contact lenses, it cannot be removed without surgery and does not require any special care.

The surgery of cataract is rarely performed on both eyes of the patient at the same time. Patients usually have to wait about a month after one cataract surgery to undergo the other. Healing from cataract surgery cantake anywhere from a few days to a few weeks. Recovery is often marked by swelling, pain and continuing blurred vision, often worse than cataract. However, as the eye adjusts, vision slowly improves until the blur completely disappears.
