Outcomes of Topography-guided LASIK and Photorefractive Keratectomy Compared to Wavefront Optimized LASIK and Photorefractive Keratectomy
Outcomes of Topography-guided LASIK and Photorefractive Keratectomy Compared to Wavefront Optimized LASIK and Photorefractive Keratectomy
This study evaluates the difference in results between eyes that have been treated wavefront optimized laser vision correction (either LASIK or Photorefractive Keratectomy) compared to eyes treated with topography-guided laser vision correction (either LASIK or Photorefractive Keratectomy). Each participant will receive wavefront optimized correction in one eye and topography-guided correction in the other.
Participants will have an in depth discussion with our refractive surgery coordinator regarding refractive surgery. Patients will choose LASIK or Photorefractive Keratectomy surgery based on our standard pre-operative discussion that is provided to all patients. As is standard for laser refractive candidates, the advantages and disadvantages of LASIK and Photorefractive Keratectomy compared to the other refractive surgical options will be discussed. Following patient selection of their preferred type of refractive procedure they will be randomized as discussed below, and only patients who elect for LASIK or Photorefractive Keratectomy will be included in our study.
Prior to surgery, one eye from each patient will be randomly assigned to receive either Wavefront optimized or Topography Guided treatment. Each patient in the study will have a fellow eye enrolled in the other treatment group. Patients will either receive LASIK treatment or Photorefractive Keratectomy treatment in both eyes but the eyes will be randomized to topography guided or wavefront optimized forms of treatment.
Inclusion Criteria:
Subjects must be at least 21 years of age and not pregnant or nursing (due to fluctuations in visual parameters during pregnancy)
