How a Cataract Surgery Is Done

Cataract is the clouding of the lens of the eyes. It affects vision. A thin lining of cloudy natural lens is removed from the eye because it blocks the passage of light. This is how a cataract surgery is done. Cataract surgery is a harmless procedure. Every year, there are more than 1.6 Americans who undergo this treatment to repair their vision. More than half of the American population have cataract or may have been through a cataract surgery by the age of 80. Some people believe that when one eye has cataract, the other eye will definitely be next. This is a myth. Cataract doesn’t spread. It can occur in either or both eyes though.

Before a cataract surgery, a patient will go through an eye examination to determine the correct power of the intraocular lens that the eye needs. It is important for the patient to mention if he is presently under some medication. The doctor will advise whether or not to continue the said medications. There are really some medications which cause problems during a cataract surgery. An example of this medicine is Flomax, which is taken by men with enlarged prostates. The patient is then given an option on what to choose over single vision intraocular lens or presbyopia-correcting intraocular lens. The patient’s choice is usually dependent on some factors such as his lifestyle and ability to pay the total cost.   

On the day of the surgery itself, there is a list of things to do such skipping breakfast and avoiding intake of liquids. An eye drop to dilate pupils and sedative are given prior to the actual procedure. Topical anesthesia is also given in order for the patient not to feel the pain. After the areas around the eyes were completely cleansed and after a sterile covering is put into place, at least a small cut is done into the eye to enable the surgeon to remove the cloudy lens. There are two methods to remove the cloudy lens. One is through sonically breaking up the cataract then extracted out of the eye. The other one is through mechanically breaking up the cataract into small pieces then removed from the eye through a small incision. After this, a plastic or silicon intraocular lens will replace the natural lens that was taken off the eye.

After the operation, a protective shield is placed on the eye. Then the patient is usually sent home after few minutes in the recovery room. Surgeons advise patients to apply eye drops for a number of times in a day. This goes on for few weeks depending on the surgeon’s advice. Just like any other medical procedure, there are dos and don’ts patients are given to ensure effectiveness of the operation.

The price of a cataract surgery is around $3,000, exclusive of health insurance. Fortunately, HMOs, Medicare and other health insurances cover this specific surgery. It is indeed pricey however, the American Society of Cataract and refractive surgery reports 98% of the patients believe it is highly recommended since it simply worked for them.
