排除标准
- •1. Acute and subacute inflammation or infection of the anterior chamber of the eye
- •2. Any eye disease, injury or abnormality that affects the cornea, conjunctiva or eyelids that would contraindicate contact lens wear;
- •3. Corneal hypoesthesia (reduced corneal sensitivity), if not aphakic
- •4. Severe insufficiency of lacrimal secretion (dry eyes)
- •5. Any systemic disease that may affect the eye or may be exaggerated by wearing contact lenses (e.g. acne and eczema)
- •6. Allergic reactions of ocular surfaces or adnexa that may be induced or exaggerated by wearing contact lenses or use of contact lens solutions
- •7. Any active corneal infection (bacterial, fungal, protozoal or viral)
- •8. Newly prescribed (within the past 30 days) use of some systemic medications (such as antihistamines, decongestants, diuretics, muscle relaxants, tranquilizers, stimulants, anti-depressants, anti-psychotics, oral contraceptives) or new prescription eyedrops which is not rewetting/lubricating eyedrops for which contact lens wear could be contraindicated as determined by the investigator
- •9. Monocular participants (only one eye with functional vision) or participants fit with only one contact lens
- •10. Subjects with slit lamp findings greater than grade 1 (e.g. edema, infiltrates, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival, anterior segment inflammation) as per ISO 11980, any previous history or signs of a contact lens related corneal inflammatory event (past corneal ulcers), or any other ocular abnormality that may contraindicate contact lens wear at the enrolment visit
- •11. History of corneal refractive surgery
- •12. Enrolment of the family members of the investigator, family members of the investigator’s staff, or individuals living in the households of these individuals
- •13. Current wearer of the control contact lenses MyDay® spherical or the test contact lenses MyDay Toric®
