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.
Detailed description
Habitual contact lens wearers were randomized 1:1:1 to one of three commercially available multifocal contact lenses. Progressive addition lens wearers wore their habitual spectacles. Subjects were expected to attend 1 or 2 office visits. This study was terminated early by Alcon due to slow enrollment and inconsistency in measurement of the primary endpoint.
