Cataract surgery is a wonderful operation that removes the lens when it has become cloudy.
In the past a large incision had to be made to remove the human lens, but nowadays the standard procedure is to make small incisions through which the lens is broken up into tiny pieces by phacoemulsification. This process utilizes high frequency ultrasound, the same as a dentist uses when he cleans your teeth, but on a much finer level.
It breaks up the cataract which measures 12mm in diameter and 4mm in thickness and removes the fragments by suction while fluid is infused into the eye. The size of the incision has also come down over the years to as small as 1,8mm, but usually varies from 3mm downwards.
A foldable lens implant has also become the standard of care. This step ensures that a person does not need to wear thick and heavy glasses after the operation as it was needed in the past. A small plastic lens is implanted which helps to focus the image in the eye. Most people do not even need glasses for distance vision after surgery. Depending on the type of lens used, some people might even be totally spectacle free. This lens has different zones that focus the image from different distances on the retina and thus causes multiple images. The up side of multiple images is that you may be able to read and see in the distance without any glasses. The down side is that you may be bothered by the multiple images.
Discuss this option with your doctor as not everyone is a candidate for this specific type of intra-ocular lens, but you might qualify. Other implants are also available that can correct astigmatism.
