Patient Reported Outcomes With WaveLight Plus LASIK

Inclusion Criteria: * Subject must be able to understand and sign an approved consent form. * Willing and able to comply with scheduled visits and other study procedures. * Age: 18 to 37 * Myopia with or without astigmatism and MRSE within the range indications for wavelight plus (myopia up to -8 D, astigmatism up to -3.0 D, S.E. more than -1.00 and up to -9.00D) * Pre-surgery BCDVA of 20/20 (0.00 logMAR) or better in each eye. * Stable refraction (within ± 0.50 D) as determined by manifest refraction spherical equivalent for a minimum of 12 months prior to surgery. * Refractive target of bilateral emmetropia * Mesopic pupil size ≥ 4.5mm * Less than 0.75 D spherical equivalent difference between Sightmap measured refraction SE and the subjective manifest refraction (MRSE) Exclusion Criteria: * Subjects with a history of previous ocular surgery. * Subjects with topographic evidence of keratoconus or ectasia. * Pre-existing retinal or corneal pathology Subjects with autoimmune diseases. * Subjects who are pregnant or nursing. * Systemic disease likely to affect wound healing, such as diabetes and severe atopy. * Any ocular disease (including uncontrolled dry eye) in which the investigator's opinion would affect the outcome of refractive surgery. * Patients with a calculated residual stromal depth \<250 µm would be excluded from the study.
