Lasik is a laser eye surgery that is used to correct vision problems such as near- or farsightedness. In lasik surgery, a laser is used to reshape the cornea of the patient. The lasik surgery can be performed as an outpatient procedure by a doctor in scrubs, though patients are advised to avoid rigorous physical activity while the eye heals. Lasik surgery can corrent many minor vision problems, though if those problems are severe enough, a patient may still require corrective lenses after the surgery .
