Participant flow
Recruitment details
A total of 126 participants (252 eyes) were enrolled. One-half of the participants were randomized to receive the investigational contact lens during the first crossover period, and the other half were randomized to receive the PureVision contact lens during the first crossover period. The participants crossed over to the other group at 1 week.

Outcome results
Visual Acuity
Visual acuity was assessed by distance high contrast logarithm of the minimum angle of resolution (logMAR).
Time frame: At 1 week follow up
Population: There were 124 eligible, dispensed participants (248 eyes). Participants/eyes received both treatment groups.
| Arm | Measure | Value (MEAN) | Dispersion |

| PureVision Multifocal Contact Lens | Visual Acuity | 0.005 logMAR | Standard Deviation 0.069 |
Symptoms/Complaints
Symptoms/complaints were assessed on a scale from 0 to 100, with 0 denoting unfavorable symptoms/complaints.
Time frame: At 1 week follow up
Population: There were 124 eligible, dispensed participants (248 eyes). Participants/eyes received both treatment groups.
