Get StartedHow you prepare
By Mayo Clinic staffA 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 proper power of the lens implant.
Your doctor may advise you to temporarily stop taking any medication that could increase your risk of bleeding during the procedure. Antibiotic eyedrops may be prescribed for use one or two days before the surgery. You may be instructed not to eat or drink anything 12 hours before the procedure.
Normally you can go home on the same day of your surgery, but you won't be able to drive, so arrange for a ride home. Also line up help around home, if necessary, because your doctor may limit activities, such as bending and lifting, for a few days after your surgery.
