About this study
Official title: Multifocal Visual Performance Study - Seamless Transition With Precision Profile MF Lenses
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.
Read the 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.

Per subject's habitual prescription
| Study group | Role | What they receive |
|---|---|---|
| Multifocal Contact Lenses | Experimental | 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. Receives: Device: Multifocal soft contact lenses |
| PAL Spectacles | Active comparator | Progressive addition lens spectacles according to the subject's habitual prescription, with testing up to 3 hours, 1 day only. Receives: Other: Progressive addition lens spectacles |
What is being measured
The primary outcome is the main question the study is designed to answer.
Average Transition Time, Calculated From a Maximum of 3 Readings, Recorded in Seconds, During Alternate Viewing From Distance (4 m) to Intermediate (80 cm) and Vice Versa (Full Analysis Set)
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 out.
Measured: Day 1, after up to 3 hours of wear

Primary outcome
Average Transition Time, Calculated From a Maximum of 3 Readings, Recorded in Seconds, During Alternate Viewing From Distance (4 m) to Intermediate (80 cm) and Vice Versa (Full Analysis Set)
Time frame: Day 1, after up to 3 hours of wear
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 out.
