What is Cataract Surgery?

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens.

  • Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.
  • Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don't have to stay in the hospital after the surgery.
  • Cataract surgery is very common and is generally a safe procedure.

Cataract surgery is a procedure to remove the cloudy lens of the eye, called a cataract, and replace it with an artificial lens, called an intraocular lens (IOL).

  • The surgery is done under local or topical anesthesia and typically takes about 30-40 minutes to perform.
  • The surgeon makes a small incision in the eye, usually about 2.2-2.8 mm, and uses ultrasound energy to break up the cataract and remove it.
  • The IOL is then inserted into the eye, where it will remain permanently. Most people experience significant improvement in their vision after cataract surgery.
  • The goal of the surgery is to improve vision and reduce glare and halos caused by cataracts.
  • Cataract surgery is typically performed as an outpatient procedure and is considered safe and effective.
