• Intended treatment from -0.5 to -6.0 D of spherical myopia
• Must have 0.50 D or less astigmatic component.
• Must have bilateral physiologic myopia
• BSCVA of 20/25 or better in each eye
• Must have had a stable refraction (0.5 D or less change in spheroequivalent) for at least one year, objectively documented (by previous clinical records, eyeglass prescriptions, etc. over one year old)
• Patients who are contact lens wearers must have hard or gas permeable lenses discontinued for two weeks and soft lenses discontinued for three days prior to the preoperative evaluation
• Must be at least 18 years of age
• Corneal topography must be normal, as judged by the investigator
• Must have a minimal corneal thickness of 475 microns
• Must sign a written Informed Consent form acknowledging their awareness of their participation in this study, the alternative treatments available, the risks involved, and the investigative nature of the procedure, and other issues which conform to the standard of care for Informed Consent practices
• Must be willing and capable of returning for scheduled follow-up examinations for 24 months after treatment

• History of herpes keratitis
• Patients with diagnosed autoimmune disease, systemic connective tissue diseases or atopic syndrome, diabetes mellitus, or taking systemic medications (i.e., corticosteroids or antimetabolites) likely to affect wound healing.
• Irregular central keratometry/topography readings with irregular topography patterns or keratometry mires, including signs of keratoconus.
• Patients with known sensitivity to study medications.
• Intraocular pressure of > 23 mm Hg by Goldmann applanation tonometry, a history of glaucoma, or glaucoma suspect.
• Women who are pregnant or nursing or who plan to become pregnant over the course of their participation in this investigation.
