LASIK: What's it all mean?

Last updated 7 years ago

If you’ve been thinking about laser vision correction, you are probably a bit confused about all the terminology that is used.  What is bladeless LASIK? Custom LASIK?  PRK?  It’s really hard to understand!  First of all, the only way to know what procedure is best for you is to have a complete LASIK evaluation at the LASIK practice.  This evaluation should include not only an evaluation of your glasses or contact lens prescription, but should include Orbscan topography.  An Orbscan will measure the thickness and curvature of your eye, the size of your pupil and any abnormalities with the cornea.  Once those calculations are reviewed, the doctor can determine the type of treatment that will offer you the best visual results.  There are 2 types of laser vision correction:

 1: LASIK (Laser Assisted In-Situ Keratomileusis)

LASIK combines the proven techniques of both corneal flap and excimer laser surgery, resulting in dramatic results and rapid visual recovery. LASIK is effective for correcting most cases of nearsightedness, farsightedness and astigmatism.   Generally, a traditional LASIK candidate would have a fairly small prescription without a significant amount of astigmatism. In addition, traditional LASIK would not improve higher order aberrations. (An example of higher order aberrations is glare and halos at night).

 2: Customized LASIK

Customized treatment means that the LASIK treatment is unique to each eye. There are several laser manufacturers, each with their own “name” for their customized treatment.  Clear Advantage uses the Bausch & Lomb Technolas laser system, which, according to the FDA, offers the highest 20/20 results of all laser manufacturers.  Their customized treatment is called Zyopitix.  With Zyoptix, the treatment is designed to treat all of your specific vision errors. Zyoptix is ideal for patients with larger prescriptions, large pupils or a significant amount of astigmatism. Zyoptix patients note improved driving ability at night with reduced or eliminated glare and halos (higher order aberrations).
