What Is LASIK?

What Is LASIK?

If you are one of the 70 million people currently diagnosed with nearsightedness (myopia), farsightedness (hyperopia), astigmatism, or a combination of these conditions, you probably have heard of LASIK (laser in-situ keratomileusis.)

This revolutionary technique uses Excimer laser technology to precisely reshape the cornea, which treats vision problems. Because of LASIK, many patients have their vision restored up to, or better than, 20/20.

How LASIK Works

LASIK uses a precise femtosecond laser to create a flap from the top layer of the cornea. The flap is gently folded back, then the laser sculpts the midcornea. This reshapes your eye, reducing or eliminating your need for glasses or contact lenses.

LASIK uses the Excimer laser to reshape the cornea under a protective layer of tissue. The Excimer laser uses cool ultra violet light to treat the cornea. It doesn't treat beyond the cornea and is extremely precise. Your LASIK surgeon will then reposition your flap. After that, the procedure is complete.

Since the surface cells of your eyes heal more quickly than any other body part, recovery is quick. Visual recovery occurs usually within 24 hours and there is minimal discomfort after surgery.

Am I a Candidate for Lasik?

LASIK is a medical procedure, and to be considered a viable candidate, individuals must fall within established parameters for refractive errors, corneal thickness, and pupil size. In addition, there are basic health and age criteria that must be met in order to ensure your safety and to help you achieve the best possible vision.

Basic Criteria to Be a LASIK Candidate

  • Between 21 and 60 years old
  • Free from certain systemic diseases, such as lupus, rheumatoid arthritis, collagen vascular disorders, and uncontrolled diabetes
  • Generally good eye health
  • Not currently taking Accutane
  • Not currently pregnant or nursing

The best way to find out whether you're a candidate for LASIK is to have a thorough examination by a qualified refractive surgeon. During your screening, our surgeon will examine your eyes, tell you about your treatment options and answer any questions you might have.
