AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

✓. They are at least 18 years of age.
✓. They understand their rights as a research participant and are willing and able to sign a Statement of Informed Consent.
✓. They have spherical refractive error at the corneal plane between +4.00 to -7.00DS
✓. They have refractive astigmatism at the corneal plane of 0.75 to 2.25DC in one eye.
✓. They are able to achieve distance HCHL visual acuity of +0.10 logMAR or better in each eye
✓. They are a current soft contact lens wearer or have previous experience of successful soft contact lens wear in the past 3 years.

✕. Is participating in any concurrent clinical or research trial.
✕. They have an ocular disorder which would normally contra-indicate contact lens wear.
✕. They have a systemic disorder which would normally contra-indicate contact lens wear.
✕. They are pseudophakic or aphakic.
✕. They have had corneal refractive surgery.
✕. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
✕. Is using any systemic or topical medications that in the opinion of the investigator may affect contact lens wear or a study outcome variable.
