What this trial studies

This clinical trial is a prospective, multi-center evaluation of the Cheetah femtosecond laser system for creating LASIK eye flaps. The study consists of two phases: the first phase focuses on optimizing the laser settings, while the second phase evaluates the quality of the LASIK flaps created using these optimized settings. Up to 300 subjects will be enrolled across multiple sites, with one eye treated in phase I and both eyes potentially treated in phase II. The study aims to assess flap lift, thickness, and diameter to ensure optimal outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with best corrected vision of 20/50 or worse who are available for follow-up visits.

Not a fit: Patients with recent eye trauma, a history of eye diseases, or conditions affecting wound healing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the quality and safety of LASIK procedures for patients with refractive errors.

How similar studies have performed: Other studies have shown success with similar laser systems, indicating potential for positive outcomes with this approach.
