Your doctor has recommended that you undergo lens replacement surgery to treat a cataract. But what does that actually mean?

The human eye is constructed like a camera - with a clear lens in the front. The lens is located just behind the iris. It is contained in an elastic capsule. This capsule will serve as the housing for the new lens. All light that enters the eye has to pass through this lens.

As we age, this lens can become cloudy and gradually lose its ability to focus properly. This is called a cataract.If left untreated, a cataract can grow steadily worse - interfering more and more with your vision.
Generally, replacing a cataract with an artificial lens is a simple procedure.

It usually involves a single incision in the white of the eye. Through this single opening the cataract is removed and the artificial lens is inserted.

While the anesthetic is taking effect, the surgeon will position a microscope in front of the eye.

By now, the pupil will be fully open, or dilated.

When the operative field is numb, the surgeon will use the microscope to help make an incision just above the iris.

Next the surgeon will open the top of the capsule and remove the lens.

Through the same incision the surgeon will insert the new lens.

Temporary sutures are used to close the incision.

Vision will gradually improve during normal healing over a period of 5 to 8 weeks.
