入选标准

  • Be at least 18 years of age as of the date of evaluation.
  • Require lens powers between -0.50 and -6.00 diopters sphere with no more than 1.00 diopter of refractive astigmatism and be willing to wear lenses in both eyes.
  • Be correctable to visual acuities of at least 20/25 in each eye with spectacles.
  • Be in good general health, based on his/her knowledge.
  • Be able and willing to adhere to the instructions set forth in this protocol and able to keep all specified appointments.
  • Possess wearable and visually functional eyeglasses.

排除标准

  • Previously unsuccessful with contact lens wear.
  • Rigid gas permeable contact lens wear within the past 12 months.
  • Previous refractive surgery; current or previous orthokeratology treatment.
  • Subject is wearing lenses in a modified monovision modality (multifocal lens in one eye). NOTE: subjects may not wear monovision lenses at any time during the study unless they are wearing spherical monovision lenses prior to enrollment.
  • Aphakia, keratoconus or an irregular cornea.
  • A known history of corneal hypoesthesia
  • Clinically significant (grade 3 or 4) anterior segment abnormalities or any infection of the eye, lids, or associated structures.
  • Ocular or systemic disease or need for medication which might interfere with contact lens wear. i.e., Sjögren's syndrome, type II diabetes, etc.
  • Slit lamp findings that would contraindicate contact lens wear, including but not limited to:
  • History of corneal ulcer, corneal infiltrates or fungal infections.
  • Pterygium, pinguecula or corneal scars within the visual axis
  • Pathological dry eye or associated findings (examples: Sjögren's syndrome, lupus erythematosus, sclerodermia)
  • Neovascularization or ghost vessels > 1mm in from the limbus
  • Seborrheic eczema, seborrheic conjunctivitis
  • History of papillary conjunctivitis greater than Grade 2 (Mild)
  • Anterior uveitis or iritis (past or present)
  • Known sensitivity to the care systems used in this study.
  • Poor personal hygiene
  • Current pregnancy or is lactating (to the best of the subject's knowledge) or subject is planning pregnancy within the next 13 months.
  • Any active participation in another clinical study within 30 days prior to this study.
  • Subject is a member, relative or household member of the office staff, including the investigator(s).
  • Subjects must read, indicate understanding of, and sign the Informed Consent Form.
