LASIK Power Correction

Overview

The clear cornea, like a prism, bends light. Light images focus onto the retina. Normal focus is sharp and clear.
With myopia, distant objects focus in front of the retina. Nearsightedness is due to a steep cornea or a longer eye.

The LASIK Procedure

LASIK treatment is performed under a thin corneal flap. A guided microkeratome blade may be used. The corneal flap is folded back.
Laser may be used to create a thin corneal flap. The laser delaminates the cornea. The corneal flap is folded back.
For treatment of myopia, the laser flattens the cornea. The thin corneal flap is returned.
Without tracking, eye movements during laser surgery can affect accuracy. With tracking, sensors monitor eye movements and the laser matches them. The resulting treatment pattern precisely matches the desired one.
The cornea focuses light onto the retina. Wavefront scanning reflects light off the retina and back through the cornea. A scan map of the cornea is made.
All corneas have small curvature variations called higher order aberrations. The wavefront scan map guides the laser to treat these variations. This provides a better overall visual result.

Summary

Advances in medical technology have made vision correction a relatively safe, fast, and effective elective procedure. Procedures shown are specific for certain surgical candidates. Refractive surgeries can have side effects and complications. Any changes to your vision should be brought to your eye care provider’s attention immediately. Surgical correction of vision, as with all surgeries, does contain and element of risk, which must be fully considered, and discussed with your eye care provider.
