This study is a single-site, single-arm, prospective, observational study of subject satisfaction, quality of vision, and quality of life after bilateral LASIK surgery. Subjects will be assessed 6 months post-operatively. Clinical evaluations will include refractive outcomes, visual acuity, and administration of the adapted PROWL, QIRC, and OSDI questionnaires.

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.

Eligible participants will be 18 to 37 years of age and who are candidates for Wavelight Plus LASIK to correct myopia or myopic astigmatism.
