Cataract Treatment

The only treatment for cataract is surgical removal. This is done when a person cannot see well enough with glasses to perform normal activities. For some people, changing glasses, getting stronger bifocals, or using a magnifying lens is helpful enough. Others choose to have cataract surgery.

If a cataract is not bothersome, then surgery is usually not necessary. Sometimes there is an additional eye problem that cannot be treated without first proceeding with cataract surgery.

Cataract surgery consists of removing the lens of the eye and replacing it with an artificial lens. A cataract surgeon will discuss the options with the patient, and together they will decide which type of removal and lens replacement is best.

LENS REMOVAL:

There are 2 types of surgery that can be used to remove lenses that have a cataract.

Extracapsular surgery consists of surgically removing the lens, but leaving the back half of the capsule (the outer covering of the lens) intact. High-frequency sound waves (phacoemulsification) may be used to soften the lens to facilitate removal through a smaller incision.

Intracapsular surgery involves surgically removing the entire lens, including the capsule. Today this procedure is done very rarely.

LENS REPLACEMENT:

People who have cataract surgery are usually fitted with an artificial lens at the same time. The artificial lens is a synthetic disc called an intraocular lens. It is usually placed in the lens capsule inside the eye.

Other options include contact lenses and cataract glasses.

Surgery can be done in an outpatient center or hospital. Most people do not need to stay overnight in a hospital. The patient will need a friend or family member to assist with travel and home care after outpatient surgery. Follow-up care by the surgeon is important.
