Cataract – Large Incision PreOp® Patient Engagement and Education

Posted on August 6, 2019 by Jason Robles


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. To begin, the surgeon will use a special instrument
to gently hold the eyelids apart. Then the surgeon will apply an antiseptic
solution to the skin around the eye before 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.
