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.
