Outcome Measures
Primary Outcomes (1)
Binocular Visual Acuity (VA) With Study Lenses at 4 Meters (logMAR)
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.
Day 2, each study lens type worn during the corresponding crossover period
Study Arms (2)
LID#224381, then AOHG MF
OTHERLehfilcon A multifocal contact lenses worn first, with lotrafilcon B multifocal contact lenses worn second in pre-determined order. Each study lens type will be worn bilaterally (in both eyes) for approximately 2 days. CLEAR CARE will be used for nightly cleaning and disinfection.

Eligibility Criteria
You may qualify if:
- 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;
You may not qualify if:
- 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;
