About this trial
This is an interventional treatment trial for Refractive Error focused on measuring myopia, presbyopia
Eligibility Criteria
Inclusion Criteria:
- Must sign an informed consent document;
- Current daily wearer of soft multifocal contact lenses for at least 6 months with symptoms of contact lens discomfort as defined by the prescreening Eligibility Questionnaire;
- Requires a near spectacle add of +0.50 to +2.50 diopters (D) (inclusive);
- Requires lenses within the power range of study lenses to be fitted;
- Best corrected VA (BCVA) of 20/30 (0.2 logarithmic minimum angle of resolution [logMAR]) or better in each eye at distance;
- Willing to wear study lenses for a minimum of 5 days per week, 6 hours per day, and attend all study visits;
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Any eye condition that contraindicates wearing contact lenses as determined by the Investigator;
- Any use of medications for which contact lens wear could be contraindicated, as determined by the Investigator;
- Monocular (only one eye functional) or fit with only 1 lens;
- Fitted with monovision;
- Prior refractive surgery (e.g., laser vision correction, photorefractive keratectomy, etc.);
- History of herpetic keratitis, ocular surgery, or irregular cornea;
- Currently wearing DT1 MF contact lenses;
- Other protocol-defined exclusion criteria may apply.

Outcomes
Primary Outcome Measures
Binocular High Contrast/High Illumination (HC/HI) Visual Acuity (VA) at Intermediate Distance (80 cm)
Visual Acuity (clarity or sharpness of vision) was measured at high contrast level. HC/HI VA was assessed binocularly (both eyes together) at 80 centimeters using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart and measured in logarithm of the minimum angle of resolution (logMAR). A lower logMAR value indicates better visual acuity.
Secondary Outcome Measures
Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score
The abbreviated CLDEQ-8 is an 8-item questionnaire used to assess comfort and dryness. Total CLDEQ-8 score ranged from 0 to 37, where a lower score represented less symptomology.
