A cataract is a clouding of the lens of the eye that can impair vision. More than half of all Americans age 65 and older have cataracts in their eyes.
Cataracts occur when there is a buildup of protein in the lens that makes it cloudy. This prevents light from passing through a normally clear lens, causing some loss of vision. In the earliest stages and more severe vision loss or even blindness in advanced stages No one knows what causes the buildup of protein responsible for clouding the lens. The cataract is a lens that has become clouded.
1. Age-related cataracts – As the name suggests, this type of cataract develops as a result of aging.
2. Congenital cataracts – Babies are sometimes born with cataracts as a result of an infection they had before they were born, due to a family history, or after for unknown reasons. they may develop during childhood.
3. Secondary cataracts – These may develop as a result of other diseases, like diabetes, or long-term exposure to toxic substances, certain medications (such as steroids), ultraviolet light, and radiation.
4. Traumatic cataracts – These can form after injury to the eye.

Bring your glasses to your visit and a current list of any medications that you are taking. Your ophthalmologist will dilate your pupil in order to examine the condition of the lens and other parts of the eye.
If you suffer from vision loss that impairs your daily life, you may be a candidate for cataract surgery, which involves removing the clouded lens and replacing it with a clear implant made of an acrylic material, silicone, or PMMA (poly methyl methalcrolate).)
During cataract surgery, the affected lens is removed and replaced by a lens implant. There are
different surgical techniques used to remove the lens.
After the cataract is removed, it is usually replaced with a new, manmade lens called an intraocular lens.
Despite claims by the manufacturer of Similasin eyedrops, there is no effective non-surgical treatments for cataracts.
Even if your natural lens is replaced with an intraocular lens, you probably will need a new eyeglass prescription. Ask your ophthalmologist about new Restor lens option. In most
cases will eliminate the need for glasses (for
distance or near) following the surgery.
Cataract surgery is usually done as an outpatient basis in an operating room under local anesthesia. Your ophthalmologist won’t remove cataracts in both eyes at the same time. You will be scheduled for two separate
Vision is usually improved within a few days after cataract surgery. Maximum improvement is usually achieved when new glasses are prescribed, several weeks after cataract surgery.
