How do I prepare for cataract surgery?

ANSWER

A week or two before your procedure, your doctor will do some tests to measure the size and shape of your eye. This helps them choose the best artificial lens for you. In addition, they'll probably tell you not to eat or drink anything for 12 hours before the surgery.
