This study was conducted to evaluate the clinical performance of an investigational silicone-hydrogel lens against Senofilcon A toric lens.

The study results were not used for design validation of the investigational product.

This will be a randomized, bilateral, 2-week cross-over, double-masked, dispensing study comparing the investigational test lens against the Senofilcon A Toric for Astigmatism control lens.

Inclusion Criteria:

• A person is eligible for inclusion in the study if they:

  1. Are at least 18 years of age and have full legal capacity to volunteer;

  2. Have read and signed an information consent letter;

  3. Are willing and able to follow instructions and maintain the appointment schedule;

  4. Are an adapted soft contact lens wearer;

  5. Require spectacle lens powers in both eyes;

     1. Sphere: between -1.75 to -6.00 diopters and
     2. Astigmatism: between -1.00 to -2.25 and
     3. Axis: 180 ± 20 degrees

  6. Are willing to wear contact lenses in both eyes;

  7. Have manifest refraction visual acuities (VA) equal to or better than logMAR (log of the minimum angle of resolution) equivalent of 20/25 in each eye;

  8. To be eligible for lens dispensing, the subject must have VA of logMAR equivalent of 20/30 or better in each eye with the study lenses and the investigator must judge the fit including toric orientation as acceptable.

Exclusion Criteria:

• A person will be excluded from the study if they:

  1. Are participating in any concurrent clinical or research study;
  2. Have any known active* ocular disease and/or infection;
  3. Have a systemic condition that in the opinion of the investigator may affect a study outcome variable;
  4. Are using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable;
  5. Have known sensitivity to the diagnostic pharmaceuticals to be used in the study;
  6. Are pregnant, lactating or planning a pregnancy at the time of enrolment (by verbal confirmation at the screening visit);
  7. Are aphakic;
  8. Have undergone refractive error surgery;

Each subject randomized to wear either the Investigational lenses (test) or senofilcon A contact lenses (control) as a matched pair and cross over to the second matched pair.

From dispense up to 2 weeks on each study lenses, a total of 4 weeks.
