Cataract Surgery: What to Expect

Cataract surgery may seem like an intimidating procedure, but it is actually one of the safest and most predictable surgeries in modern medicine. If your vision has become compromised by the blurry, distorting effects of cataracts, cataract surgery can repair your vision by removing your cloudy natural lens and replacing it with a new artificial lens.

How to Prepare for Cataract Surgery

Prior to your cataract surgery, Dr. Khanna will:

  • Discuss in detail exactly what you can expect from the procedure.
  • Perform a complete eye exam, and thoroughly review your medical history.
  • Determine the type of refractive lens you will use.
  • Provide you with instructions about what to eat and drink before your surgery.
  • Provide you with instructions about which medications you should stop taking before your surgery.

Since cataract surgery is an outpatient procedure, you will be able to go home shortly after the surgery is finished. However, you should arrange for a friend or family member to drive you home. It’s also a good idea to have chores, errands, and meals completed ahead of time so you can rest right away.

The Cataract Surgery Procedure

Cataract surgery is performed under local or topical anesthesia. You may also be provided with a sedative to help keep you relaxed and anxiety-free. The surgery itself takes up to 30 minutes to complete.

During the procedure, your cataract(s) will be removed using ultrasonic energy, which will gently break up the cataract and allow it to be suctioned away. You may feel some amount of pressure on your eye during the procedure, but you should not feel any significant discomfort. Once the cataract has been successfully removed, Dr. Khanna will place your new artificial intraocular lens (IOL) into your eye. Again, you should not feel any pain while this is happening, and after your surgery, you will not be able to “feel” the artificial lens inside of your eye.

It can take several days to notice vision improvement. This is because your eyes will need time to adjust to a new lens. However, you can expect to see your final results within a month.
