About this study

Subjects will be expected to attend 3 scheduled visits. Eligible subjects will wear each study lens type in a cross-over fashion for approximately 2 days.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Able to understand and sign an consent form (ICF) that has been approved by an Institutional Review Board (IRB);
  • Willing to stop wearing habitual contact lenses for the duration of study participation;
  • Currently wearing multifocal soft contact lenses in both eyes for a minimum of 5 days per week and 8 hours per day during the past 3 months;
  • Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

  • Any eye infection, inflammation, or abnormality or disease (including systemic) that contraindicates contact lens wear, as determined by the investigator;
  • Any use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the investigator;
  • History of refractive surgery, or plan to have refractive surgery during the study;
  • Current or history of dry eye in either eye that would preclude contact lens wear, in the opinion of the investigator;
  • Monovision contact lens wear;
  • Other protocol-defined exclusion criteria may apply.

Primary outcomes

  1. Binocular Visual Acuity (VA) With Study Lenses at 4 Meters (logMAR)

    Time frame: Day 2, each study lens type worn during the corresponding crossover period

    VA was assessed binocularly (both eyes together) using a letter chart and measured in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with lower logMAR values indicating better visual acuity. No hypothesis testing was prespecified for this endpoint.
