Study Completion Date: January 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Test Group myopia control
Subjects wearing contact lenses made of LSH (mangofilcon A) Soft (hydrophilic) Contact Lens for myopia control
Device: Lagado LSH (mangofilcon A) Soft (hydrophilic) Contact Lens
Daily Wear
Active Comparator: Myopia Control
Subjects wearing Benz 3GX (hioxifilcon B) Soft (hydrophilic) Contact Lens for myopia control
Device: Benz 3GX (hioxifilcon B) Soft (hydrophilic) Contact Lens


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Have been advised that the contact lenses they will be wearing for the next 3 months are being used for investigational purposes and that their informed consent will be needed and documented prior to the start of the study.
  • Visual acuity must be correctable to 20/30, with spherical lenses ranging in power from -1.00 to -5.00D, astigmatism≤1.50D.
  • Have been successfully wearing soft (hydrophilic) contact lenses for at least one month prior to entering the study. (Success means both subject and practitioner are satisfied with visual acuity, comfort, and ocular physiology).
  • Have non-diseased eyes which are normal or which have no preexisting ocular condition which would interfere with the patient's ability to adapt to the new pair of LSH Silicone Hydrogel Soft (hydrophilic) Contact Lenses. A normal eye is defined as one having all the following characteristics:

    1. No evidence of lid infection.
    2. No structural lid abnormality.
    3. No conjunctival abnormality or infection.
    4. A cornea which is clear with no edema, staining, vascularization or abnormal opacities, all as observed by slit lamp examination.
    5. No iritis.
    6. No other active ocular disease that would contraindicate use of the investigational lens.
    7. No GPC (giant papillary conjunctivitis, tarsal abnormality) Grade 2 or greater
  • Use no ocular medication.
  • Have no known sensitivity to solutions currently used for contact lens care.
  • Have binocular correction with contact lenses.

Exclusion Criteria

  • Astigmatism >1.50D
  • No monocular or monovision fits may be included.
  • Pregnant and lactating women are excluded from the study
  • Minors (under age 18) are excluded from the study
