Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

This was a double-masked trial for the contact lens wearers. The PAL wearers were not masked.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Multifocal Contact Lenses

Multifocal soft contact lenses according to the subject's prescription and fitted using the Alcon multifocal fitting guide. Lenses were worn bilaterally (in both eyes) for up to 3 hours, 1 day only.

Group Type EXPERIMENTAL
