Eye Cataract Lens
Eye cataract lens information is valuable to understand before one goes for cataract surgery. Cataract is a disorder of the eye where there is cloudiness of the lens. Individuals who develop cataracts often develop "ghost vision" and blurry vision that makes it hard to see almost anything. In cataract eye surgery, the cloudiness in the lens is removed and a new lens is implanted. Eye cataracts are quite common and by the age of 70, almost 33% of the population has some degree of cataracts.
Eye cataract surgery is done under local anesthesia and is an outpatient procedure. Individuals who are very anxious can be given an intravenous sedative to help calm the nerves. Individuals who are not able to following instructions, young children or those who have allergies to local anesthetics are administered general anesthesia. The surgeon removes the damaged lens using a variety of techniques and then inserts an artificial lens. In most cases, the small incision is not sutured and heals on its own. After surgery, an eye patch is placed which must be worn at night to prevent accidental scratching of the operated eye. The eye protective shield is usually worn for 7-10 days at night; during the daytime one may wear sunglasses that can keep out the bright lights. Usually there is no pain after surgery but one may develop mild itching and tearing. The first visit to the surgeon is usually the following day and subsequent visits are every few weeks. After cataract eye surgery, the majority of individuals have either a reduced need for glasses or no need for glasses.
Eye cataract surgery is very safe today and 90% of individuals get an excellent result. About 10 percent will develop some type of complication like a decrease in vision, double vision, increasing redness, pain, swelling of discharge from the eye.
Like all surgeries, there is a certain risk of cataract surgery. This risk is increased when one also has other problems of the eye like glaucoma, diabetes or severe hypertension. While come complications can be treated others like vision loss cannot be reversed. Mild complications that occur after surgery and which do reverse include problems with bright lights and tearing. Individuals who have the lens dislocation or those who have clouding of the new lens can undergo another surgery with good results. For consumers it is vital to seek the help of a surgeon who has experience doing cataracts surgery. The greater the experience of the surgeon, the fewer the chance of complications. Since eye cataract lens surgery is an elective procedure, the first thing one should do is to look for a surgeon with a great safety record.
