About Laser Vision Correction

LASIK stands for Laser Assisted In-Situ Keratomileusis. 

  • LASIK works by creating a thin flap in the upper portion of the cornea.  Both microkeratome-based and femtosecond-based LASIK generally have good outcomes with few complications. 
  • Using a cool excimer laser, the surgeon reshapes the cornea allowing light and images to focus precisely onto the retina to produce clear vision.

Still widely used, Photorefractive Keratectomy or PRK may be the recommended refractive procedure as an alternative to LASIK for selected patients. 

  • PRK differs from LASIK in that a corneal flap is not made.  
  • The eye surgeon gently removes the outer layer of cells (the epithelium) then applies a cool excimer laser to reshape the cornea.
  • Since it may take a few days for the epithelium to heal, patients may experience minimally more discomfort with PRK than LASIK.

Both LASIK and PRK are extremely safe and effective eye procedures to treat a wide range of common vision problems including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. 

CustomVue LASIK at Chao Vision Institute
The VISX Technology WaveScan WaveFront STAR S4 IR Advantage

The WaveScan WaveFront™ System and the STAR S4 Excimer Laser System with Iris Registration (Abbott Medical Optics) is the first FDA-approved, fully automated method of aligning and registering wavefront corrections to deliver unprecedented levels of measurement accuracy and outstanding treatment precision essential to the Custom Vue procedure.  

WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space.

Compared to standard methods used for glasses and contact lenses, Wavefront technology identifies and measures imperfections in a patient's eye 25 times more precisely.
