How you prepare

By Mayo Clinic Staff

To prepare for your cataract surgery, you may be asked to:

  • Undergo tests. A week or so before your surgery, your doctor performs a painless ultrasound test to measure the size and shape of your eye. This helps determine the right type of lens implant (intraocular lens, or IOL).
  • Stop taking certain medications. Your doctor may advise you to temporarily stop taking any medication that could increase your risk of bleeding during the procedure.
  • Use eyedrops to reduce infection risk. Antibiotic eyedrops may be prescribed for use one or two days before the surgery.
  • Fast before surgery. You may be instructed not to eat or drink anything 12 hours before the procedure.
  • Prepare for your recovery. Normally you can go home on the same day as your surgery, but you won't be able to drive, so arrange for a ride home. Also arrange for help around home, if necessary, because your doctor may limit activities, such as bending and lifting, for about a week after your surgery.
