Description
Inclusion Criteria:
- Myopic subjects between 8 and 12 years of age.
- The subject best sphere contact lens correction must lie between -0.75D (best of the two eyes) and -5.00D (worst of the two eyes)
- Astigmatism must be less than or equal to 1.00D
- 1.00D or less difference in spherical equivalent between the two eyes
- The subject must have a best-corrected visual acuity of 0.8+2 (20/25+2) and spherical equivalent refraction visual acuity of 0.820/25) or better in both eyes
- The subject must have at least 8D of accommodation
- The subject and subject's parent or legal guardian must read and sign the STAEMENT OF INFORMED CONSENT
- The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
Exclusion Criteria:
- Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
- Systemic disease or autoimmune disease or use of medication (e.g. antihistamine), which may interfere with 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
- Anisometropia of greater than 1.00D
- Astigmatism of greater than 1.00D in either eye
- Eye injury or surgery within eight weeks immediately prior to enrollment for this study.
- Pervious refractive surgery, rigi contact lens wear, orthokeratology, keratconus or other corneal irregularity in either eye.
- Strabismus in either eye
- Pupil orr 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
- Surgically altered eyes, ocular infection of any type, ocular inflammation
- Subject has anterior chamber angle grade 2 or narrower

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Spherical Equivalent Refraction
Time Frame: Baseline and every 6 months post-baseline for 2 years
|
Spherical equivalent refraction was computed from the sphero-cylindrical refraction measured with an open-field auto refractor (WAM-5500) and descriptively summarized for each follow-up.
Higher spherical refraction indicates progression in Myopia.
|
Baseline and every 6 months post-baseline for 2 years
|
Axial Length (Axial Elongation)
Time Frame: Baseline and every 6 months post-baseline for 2 years
|
Axial length was measured with the IOLMaster at baseline and every 6 months post-baseline for 2 years.
Axial length was descriptively summarized for each follow-up.
|
Baseline and every 6 months post-baseline for 2 years
