Study Summary
The purpose of this trial was to compare the functional visual performance of Precision Profile Multifocal (MF) contact lenses to Progressive Addition Lens (PAL) spectacles in a presbyopic population.
Primary Outcome
The subject was asked to read text at distance (4 meters) or intermediate (80 centimeters), followed immediately by text at the alternate viewing (intermediate or distance). The interval between when the subject stopped reading the first text and started reading the second text is defined as the transition time. Due to inconsistent measurement of the primary endpoint in this study, interpretation of the average transition times was compromised and the planned inferential analysis was not carried
Interventions
- DEVICE Multifocal soft contact lenses
- OTHER Progressive addition lens spectacles
