How is LASIK surgery performed?
After anesthetic drops are applied to the eye, the surgeon creates a protective flap using the bladeless IntraLase® laser or a handheld surgical instrument. This flap is then gently lifted as the surgeon applies computer-controlled pulses of cool laser light to the inner layers of the cornea. The inner corneal layer is reshaped with the laser to improve vision or eliminate the need for prescription lenses.
The procedure uses Iris Registration, an alignment method that maps 40 points on the iris and focuses the laser using these points, to track eye movements to ensure precise correction. When one lies down, the eyes naturally rotate and the pupils may migrate. Iris Registration detects any eye movement and allows the laser to rotate with these movements to ensure accurate treatment. The surgeon then gently replaces the flap and aligns it to its original position.
To prevent accidental rubbing while the flap is healing, patients will be given a protective shield to wear at night following surgery. Some patients may feel slight irritation for a few hours, but most are quite comfortable after a nap and rest.
The entire LASIK surgery takes approximately 15 to 20 minutes. Most patients will experience a 50% improvement by that evening and 70% improvement by the next day. A patient’s vision should be fully restored within 1 – 4 days without the need for any corrective lenses. Most patients return to regular daily activity within 24 hours.
