Summary

This purpose of this study is to compare a new form of LASIK called Ray Tracing Guided LASIK to 3 other forms of corneal refractive surgery: 1. KLEx (KeratoLenticule Extraction) using the Zeiss Visumax 800 Laser, 2. WFO LASIK (Wavefront Optimized LASIK) using the Alcon EX500 Laser, and 3. Topography Guided LASIK (Contoura LASIK) also using the Alcon EX500 Laser.

Conditions

  • Myopia
  • Astigmatism

Interventions

DEVICE

Ray-Tracing Guided LASIK

A form of LASIK where Ray-Tracing technology is used to create the surgical profile for treating the cornea.

DEVICE

Keratorefractive Lenticule Extraction (KLEx)

A form of corneal refractive surgery utilizing a femtosecond laser to create a lens shaped lenticule of corneal tissue that is removed through a small corneal incision.

DEVICE

WaveFront Optimized LASIK

A form of LASIK where the corneal treatment profile is modified to decrease induced Spherical Aberration.

DEVICE

Topography Guided LASIK

A form of LASIK where a corneal topography of the cornea is used to create the surgical profile for treating the cornea.
