Outcome Measures
Primary Outcomes (1)
The Percentage of Eyes Achieving the Target of Monocular Uncorrected Visual Acuity of 20/40 or Better
At 6 months, UCVA of 20/40 was achieved in 100% (324/324) of eyes monocularly.
6 months
Study Arms (1)
wavefront-guided PRK with iDesign
EXPERIMENTALwavefront-guided PRK for treatment of myopic refractive errors based upon measurements obtained with the iDesign System using the STAR S4 IR laser
Interventions
Surgeons will perform wavefront-guided PRK for the treatment of myopic refractive errors based upon measurements obtained with the iDesign System using the STAR S4 IR laser.
Eligibility Criteria
You may qualify if:
- 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.
You may not qualify if:
- 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.
- Desire to have monovision.
- Participation in any other clinical study, with the exception of the fellow eye in this study.
