Cataract is the changing of the clarity vision of the natural lens in the eye which becomes blurred. Most people with the age over 60 experience this kind of disease. This disease is very common at older people. A cataract can be placed at one eye or at both eyes. But you don’t have to worry about spreading. This can not happen. Let’s understand about Cataracts.
The cataract surgery is done in a hospital or in an ambulatory center.
There are three methods for cataract surgery:
Phacoemulsification is a form of cataract surgery. For this method it is used a microscope. The doctor will make a small incision in the eye area. Once the cataract is out, the natural lens will be replaced with an artificial one. This method is the most used form of cataract removal. This type of surgery needs minimal sedation and eye drops but there is no need for stitches.
Extracapsular cataract surgery. This is a method used for very advanced cataracts. This type of cataract surgery method needs a larger incision so that the cataract can be removed at once without being fragmented in the eye. This method is requiring a various number of sutures for closing the wound. The recovery is slower than the one from phacoemulsification.
Intracapsular cataract surgery. The intracapsular cataract surgery needs an even larger incision, because the doctor will be forced to remove the entire lens. This method requires that the lens are placed in front of the flag (iris). It is a very rare method. Nowadays is rarely used.
The cataract surgery procedure starts by placing some eye drops in your eyes for pupil dilatation and anesthetize the area of your eye. The anesthesia is enough for patients to feel just about nothing. The surgeon will insert an instrument through a small incision and after this he will use an ultrasound for breaking your cataract. Your natural lens will be replaced with the artificial lens. The artificial lens will be inserted through the same small incision. During the operation you will be aware of everything what happens, but you will be unable to see the surgery itself.
