Laser vision correction has been performed for more than twenty years. Procedures and lasers have improved to allow better results and correction for higher refractive errors. Wavefront technology was introduced fifteen years ago. The result was less glare and distortion after the procedure.
Laser vision correction works by removing corneal tissue to correct refractive error. For example, someone who is nearsighted or myopic typically has a longer eye and/or steeper cornea. The laser removes tissue to flatten the cornea and focus light accurately on the retina. In someone with astigmatism the tissue is removed to create corneal symmetry that will eliminate blur.
LASIK (laser in-situ keratomileusis) is the most common refractive laser procedure. It combines the accuracy of the Excimer laser with the quick-healing characteristics of Lamellar Keratoplasty. Lamellar keratoplasty is a procedure where a hinged flap of the cornea is created. The excimer laser is used to treat the underlying cornea. The hinged flap is set back in place where it securely bonds without stitches.
Who is a candidate for LASIK?
A good candidate for LASIK has a stable prescription, realistic expectations and thick enough corneas. The decision to have laser vision correction is important. Outcomes are very good, but complications do occur and 20/20 vision isn’t a guarantee. Ask about laser vision correction at your next visit with us.
