Clinical Investigation of the Cheetah System For The Correction of Myopia With and Without Astigmatism

Inclusion Criteria: Note: All criteria apply to each Cheetah treated eye * Age ≥18 years old at the time of consenting. * Subjects with refractive error within the following ranges: * Phase I: Partially sighted eyes (as defined below) * Phase II: Refractive error range in the Cheetah-treated eye/s between -2.00 D to -6.00 D and astigmatism up to -1.00 D based on manifest refraction at optical infinity. If cyclotorsion correction after docking is available, astigmatism greater than -1. 00 D can be included, provided that spherical equivalent (SE) is up to -6.00 D. * Phase III: Myopic refractive error in the study eye up to -12.00 D spherical equivalent (SE) and astigmatism up to - 6.00 D based on manifest refraction at optical infinity. * Anticipated residual corneal stromal thickness of at least 250 microns based on preoperative corneal pachymetry minus maximum lenticule thickness to be extracted. * Uncorrected visual acuity of 20/40 or worse in Phase II and III subjects. * Distance Best Spectacle Corrected Visual Acuity (BSCVA) of 20/20 or better for phase II and III subjects. For phase I subjects, BSCVA and pin-hole acuity of the iLEX treated eye is worse than 20/50, with at least a 2-line difference between the iLEX treated eye and the fellow eye. Note: Potential phase I subjects to be evaluated on a case-by-case basis for interocular difference in visual acuity and enrollment to be confirmed through Medical Monitor and PI consensus. * BSCVA ≥2 lines better than…
