Outcome Measures
Primary Outcomes (8)
Lines of improvement of monocular UCVA at the 12-month visit (overall and stratified by baseline sphere)
The number of lines of change in acuity (for an eye) is defined as the difference in the logMAR acuities, scored to the letter, multiplied by 10. Each line difference represents 0.1 logMAR acuity. The improvement in acuity is represented by a numerical reduction in the logMAR value. The primary effectiveness endpoints described above will also be stratified by subjects' baseline age (including 7 to 11 years (children), 12 to 21 years (adolescents), and 22 years and older (adults) .

Study Arms (1)
Acuity 200™ (fluoroxyfocon A) Orthokeratology Contact Lens for Overnight Wear
OTHERFor the orthokeratology treatment the subjects will be instructed to wear the study lenses each night during the hours of sleep (for a minimum of 6 hours) and remove the lenses during the waking hours. The subject will be examined at 1 day, 1 week, 1 month, 3 months, 6 months, 9 months and 12 months after dispensing to evaluate the ocular physiology and the treatment effect. The target refractive error (sphere) will be plano for all subjects. All subjects enrolled at two of the investigational sites (targeted total of 40 subjects) will be evaluated for the stability of UCVA and manifest refraction throughout a single day on or following the 3 month, 6 month, or 9 month follow up visits. A post-treatment follow-up visit will be scheduled 1 month following discontinuation of the study lens. When it has been determined that no additional follow up visits are required, the subject will be discharged from the study.
Interventions
Acuity 200™ Orthokeratology Contact Lenses are intended to be worn overnight with removal during following day. The lenses are designed to produce a temporary reduction of myopia by reversibly altering the curvature of the cornea. The lenses are manufactured from fluoroxyfocon A, which is a gas permeable contact lens material composed of a siloxanyl fluoromethacrylate copolymer. The material name fluoroxyfocon A is registered with United States Adopted Name (USAN).The Acuity 200™ (fluoroxyfocon A) Orthokeratology Contact Lens is available in spherical, asymmetrical, aspheric, and tangential lens designs to best fit the individual cornea, using corneal topography and/or diagnostic lenses.

- Has a history of intraocular or corneal surgery (including cataract extraction and refractive surgery-such as Lasik), active ophthalmic disease or abnormality (including, but not limited to, blepharitis, recurrent corneal erosion, dry eye syndrome, neovascularization \> 1mm from limbus), clinically significant lens opacity, clinical evidence of trauma (including scarring), or with evidence of glaucoma or propensity for narrow angle glaucoma as determined by gonioscopic examination in either eye. NOTE: This includes any subject with open angle glaucoma, regardless of medication regimen or control. Additionally, any subject with an IOP greater than 21 mm Hg at baseline is specifically excluded from eligibility.
- Has evidence of keratoconus, corneal irregularity, or abnormal video-keratography in either eye.
- Has a pupil size greater than 6.0 mm in photopic illumination as measured with pupil detection component of computer assisted video keratography.
- Has a corneal diameter of 10 mm or less;
- Has flat keratometry values flatter than 38.00D (8.88 mm), or steeper than 47.00D (7.16 mm);
- Takes medication that may cause dry eye or affect vision, corneal curvature, or healing (i.e., corticosteroids);
- Has an allergy to any ingredient in the study lens care solutions;
- Has significant ocular allergy, which would contraindicate solution use and/or "normal" contact lens wear;
- Is currently using or has a history of atropine use for myopia progression control
- Is a current wearer or previous wearer within the last 90 days of daily wear rigid gas permeable contact lenses, extended wear rigid gas permeable contact lenses, or orthokeratology contact lenses;
- Is participating in any other type of clinical or research study.
