Myopia Progression After Ceasing Myopia Control Contact Lens Wear
- Conditions
- Myopia
- Interventions
- Device: 1 Day Acuvue Moist
- Registration Number
- NCT01829230
- Lead Sponsor
- Johnson & Johnson Vision Care, Inc.
- Brief Summary
This is a continuation study for subjects who were previously fit with test or control lenses; all will stop wearing their study lenses assigned in the previous study and will start to wear an FDA-approved marketed spherical soft contact lens.

- The subject must be enrolled in the parent protocol for at least one year.
- The subject's parent or legal guardian must read and sign the STATEMENT OF INFORMED CONSENT and the subject must read and sign the Child's Assent Form and be provided a copy of each form.
- The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
- Ocular or systemic allergies that may interfere with contact lens wear.
- Systemic disease or autoimmune disease or use of medication (e.g. antihistamine), which may interfere with contact lens wear.
- Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining or any other abnormality of the cornea, which may contraindicate contact lens wear.
- Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection that might interfere with contact lens wear.
- Any ocular infection.
- Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
- Any infectious disease (e.g. hepatitis, tuberculosis) or an immunosuppressive disease (e.g. HIV)
- Diabetes
- Previous refractive surgery, orthokeratology, keratoconus, or other corneal irregularity in either eye. Rigid contact lens wearers cannot be enrolled in the study.
- Strabismus.
- Pupil or lid abnormality or infection in either eye
- Central corneal scar in either eye
- Aphakia in either eye
- Contraindications to contact lens wear such as dry eye or history of prior unsuccessful contact lens wear.
- History of participation in prior clinical trials aimed to control myopia progression, except for the parent trial
- Surgically altered eyes, ocular infection of any type, ocular inflammation.
- Anterior chamber angle grade 2 or narrower by Van Herrick method.

- Primary Outcome Measures
Name Time Method Spherical Equivalent Refractive Error Baseline and every 6 months up to 18 months Cycloplegic spherical equivalent refraction of the subjects's right eye was computed from the sphero-cylindrical refraction measured with an open-field auto refractor. The median of 5 repeated measurements, each of which was the average of 3 consecutive readings, was used for the analysis.
Axial Length of the Eye Baseline and every 6 months post-baseline up to 18 months Axial length was measured with the IOLMaster at baseline and then every 6 months throughout the course of the study. Five measurements were collected at each visit from the subject's right eye and the average of the 5 measurements was used for the analysis.
