Cataract removal

Cataract removal

Definition

Cataract removal is a procedure to remove a clouded lens (cataract) from the eye. Cataracts are removed to improve vision. The procedure almost always includes the replacing the lens of the eye with an artificial lens.

Alternative Names

Cataract extraction; Cataract surgery

Indications

Cataract surgery is usually recommended for people who have loss of vision or vision abnormalities caused by clouding of the lens.

Convalescence

Because this operation is usually performed on an outpatient basis, the patient returns home the same day. Expect complete healing in about 10 weeks.

Expectations after surgery

The outcome of cataract surgery is usually excellent. The operation has low risk, the pain is minimal and recovery time is short. Improvement in sight occurs in most cases. Ninety-five percent or more of all cataract surgeries result in improved vision.

Risks

Complications of cataract surgery are not common, and serious complications are rare. Most patients have better vision after cataract surgery.

In about 3% - 4% of cases, the entire lens cannot be removed and another procedure is required at a later date to remove all of the lens fragments. Most of these patients still do very well. In other very rare cases, infection can occur after cataract surgery, which can lead to permanent vision problems.

FREQUENTLY ASKED QUESTIONS:

Q: Will a laser be used to remove my cataract?

A: No. Lasers are not used to remove cataracts, though they likely will be in the future. Several months after the surgery, a laser can be used to break apart remaining old lens fragments sitting behind the new artificial lens, if necessary.

Q: Will it harm my eye to wait to remove the cataract?

A: No. Cataracts do not harm the eye. You should have your cataract removed when it is convenient for you and only if you are unhappy with your vision.

Q: If I have a cataract in each eye, can I have them both done at the same time?

A: No. Usually one eye is allowed to heal before the operation is repeated on the other eye. Most surgeons recommend waiting 1 to 2 months between procedures.
