All modern refractive procedures employ an Excimer or UV laser with or without a corneal flap. Myopia (nearsightedness), Hyperopia (farsightedness), Astigmatism (the football-shaping of the cornea or surface of the eye) and near vision can all be corrected.

In the flap procedures (epi-LASIK and LASIK), the surgeon fashions a partial thickness flap in the cornea in order to access a tissue base that will be reshaped by the Excimer laser. LASIK (an acronym for Laser-Assisted in situ Keratomileusis) involves cutting the flap in the top 1/3 of the corneal stroma fashioning a bed for the laser treatment and subsequently correcting the patient?s refractive error. In Epi-LASIK, a safer and ultimately more effective procedure, the flap is made in the more superficial layers of the cornea.

In Surface Ablation or Photorefractive Keratoplasty (PRK), no flap is made. The Laser alone reshapes the cornea.

Custom Wavefront technology constitutes the most technologically advanced refractive procedure. Prior to surgery, the patient?s corneas are topographically mapped by an instrument called an aberrometer quantifying areas of steepness and flatness. These areas, unique to each patient?s cornea contribute to higher order refractive errors. When these are corrected with a Custom Wavefront laser, high-definition vision (sometimes better than 20/20) can be attained.

Dr. Masi is currently employing the VISX Star 4 Custom Wavefront Excimer laser with a 3.90 software upgrade. This state-of-the-art Excimer laser can produce high definition vision for his patients.
