Study Summary

The objectives of this study are to evaluate the safety and efficacy, with regards to regression of refractive outcome, as measured by manifest refraction spherical equivalent (MRSE), of two treatment regimens for hyperopic and hyperopic astigmatic subjects: LASIK followed by cross-linking performed with the KXL System and Photrexa ZD™ (Riboflavin Ophthalmic Solution), as compared to LASIK alone.

Primary Outcome

The co-primary efficacy endpoints are a comparison of MRSE regression in the refractive outcome between the LASIK only eyes and the LASIK with cross-linking eyes within each treatment type and duration (2 minutes continuous UVA or 3 minutes pulsed UVA cross-linking) expressed as the change between one week and six months, and one week and twelve months.

Interventions

  • DRUG riboflavin ophthalmic solution, 0% dextran
  • DEVICE UVA Irradiation (30 mW/cm2 for 2 minutes continuous UVA)
  • DEVICE UVA Irradiation (30 mW/cm2 for 3 minutes pulsed UVA with an on/off cycle of 2 seconds UVA on/1 second UVA off)
  • PROCEDURE Laser-assisted in situ keratomileusis
