Cataract surgery FAQ
Answers to the most common questions patients ask before cataract surgery.
Frequently asked questions
Is cataract surgery painful?
For most patients, no. Numbing eye drops keep the eye comfortable throughout, and any post-operative discomfort is typically mild scratchiness rather than pain.
How long does cataract surgery take?
The surgical portion is typically quick — commonly 10 to 20 minutes per eye — though plan for a few hours total at the surgical center including preparation and monitoring.
Will I be awake during cataract surgery?
Yes, in the great majority of cases. Local anesthesia keeps you comfortable while awake; general anesthesia is uncommon and reserved for specific situations.
How soon can I drive after cataract surgery?
Often within a few days to about two weeks, once your vision meets the required standard — always confirm with your surgeon rather than assuming.
Can cataracts come back after surgery?
No — once removed, a cataract cannot regrow. What's sometimes called a "secondary cataract" is a different, unrelated condition (PCO) that's easily treated with a brief laser procedure.
