Like any operation, small-incision cataract surgery requires preparation.
Your eye doctor will review your health history. Based on that, he or she may order tests or talk to your other health care providers. Tell your eye doctor which medicines you take. That includes over-the-counter medicine such as aspirin.
You will have a complete eye exam. Your eye doctor or a technician will use devices that measure the length and curve of your eye. These measurements let your doctor select the proper new lens (IOL or intraocular lens) for you.
Don’t eat or drink anything after midnight the night before your surgery. This includes water, coffee, chewing gum, and mints. If you have been told to continue your daily medicine, take it only with small sips of water. Make sure you follow any other instructions your doctor gives you.
Have someone you know drive you to and from the outpatient surgery clinic or hospital. Plan to be there for about 2 to 3 hours. When you arrive, you’ll sign a consent form if you haven’t done so already. This form explains the risks of surgery. Just before surgery, your doctor will give you medicine that will relax you and keep you from feeling pain. You may sleep lightly.
Your doctor may have to shift from a small incision to a larger incision.
There is a small chance of bleeding, infection, or swelling.
