Outcome Measures
Primary Outcome Measures
- The Percentage of Eyes Achieving the Target of Monocular Uncorrected Visual Acuity of 20/40 or Better [6 months]
At 6 months, UCVA of 20/40 was achieved in 100% (324/324) of eyes monocularly.
Eligibility Criteria
Criteria
NOTE: Enrollment open only to military personnel
Inclusion Criteria:
-
Signed informed consent and HIPAA authorization.
-
Refractive error, based on the iDesign displayed refraction must be myopia with or without astigmatism with sphere up to -8.00 D, and cylinder between 0.00 D and -4.00 D with maximum SE of -10.00 D.
-
Anticipated residual stromal bed thickness of at least 250 microns as calculated by the iDesign system.
-
Distance Best Spectacle Corrected Visual Acuity (BSCVA) of 20/20 or better
-
BSCVA ≥2 lines (≥10 letters) better than distance Uncorrected Visual Acuity (UCVA).
-
Less than or equal to 0.75 D difference between cycloplegic and manifest refraction sphere.
-
Stable refractive error as defined by a change of ≤1.00 D in MRSE over at least a 12 month time period.
-
Any subject eye with a history of contact lens wear within the last 4 weeks must demonstrate refractive stability
-
Agreement between manifest refraction (adjusted for optical infinity) and iDesign System refraction chosen for treatment.
-
Willing and capable of complying with follow-up examinations for the duration of the study.
Exclusion Criteria:
-
Women who are pregnant, breast-feeding, or intend to become pregnant, or not using an adequate method of birth control.
-
Concurrent use of systemic (including inhaled) medications that may impair healing.
-
History of any of the following medical conditions, or any other condition that could affect wound healing: collagen vascular disease, autoimmune disease, immunodeficiency diseases, ocular herpes zoster or herpes simplex, endocrine disorders (including, but not limited to unstable thyroid disorders and diabetes), lupus, and rheumatoid arthritis.
-
Subjects with a cardiac pacemaker, implanted defibrillator or other implanted electronic device.
-
History of prior intraocular or corneal surgery, active ophthalmic disease or abnormality, retinal detachment/repair, clinically significant lens opacity, clinical evidence of trauma, corneal opacity within the central 9 mm and visible on topography, at risk for developing strabismus, or with evidence of glaucoma or propensity for narrow angle glaucoma.
-
Evidence of keratoconus, corneal dystrophy or irregularity, or abnormal topography
-
Known sensitivity or inappropriate responsiveness to any of the medications used in this study.
-
If either eye does not meet all inclusion criteria
-
Desire to have monovision.
-
Participation in any other clinical study, with the exception of the fellow eye in this study.
