Trial Outcomes & Findings for Clinical Evaluation of Biofinity Multifocal Compared With Air Optix Aqua Multifocal and With PureVision Multifocal (NCT NCT01591499)

NCT ID: NCT01591499

Last Updated: 2020-08-11

Results Overview

The percentage of participants who obtained binocular distance and near visual acuities (VA) at least as good as their initial refraction assessment. Measured by Initial Refraction. Distance binocular VA (at 5 meters) using the Snellen chart decimal scale and near binocular VA (at 40 cm) using the Parinaud chart (smallest to largest letters, Score P1.5, P2, P4, P5). Change over time measured at V1 (initial refraction) and at V3 (lens pair one evaluation) and V5 (lens pair two evaluation): V1 = initial refraction at baseline, V3 = after 17-24 days of lens wear pair one, V5 = after 17-24 days of lens wear pair two

SECONDARY outcome

Timeframe: Measured at 17-24 days V3 or V5

Population: (Participant Flow: Biofinity Multifocal N=138, 6 missing values; Air Optix Aqua Multifocal N=70, 5 missing values; Purevision Multifocal N=68, 5 missing values)

The ophthalmologist's rating of lens wettability by questionnaire as a limited selected response (Zero, Low, Acceptable, Good or Excellent). Assessed with the slit lamp and reported per lens. Measured at V3 (lens pair one evaluation) or V5 (lens pair two evaluation): V3 = after 17-24 days of lens wear pair one, V5 = after 17-24 days of lens wear pair two

SECONDARY outcome

Timeframe: Measured at V5

Population: (Participant Flow: Biofinity Multifocal/Air Optix Aqua Multifocal N=70, 8 missing values; Biofinity Multifocal/Purevision Multifocal N=68, 7 missing values; Evaluated at least one lens N=138, 15 missing values.)

The number of participants who preferred a lens pair rated by diary questionnaire with a limited selected response.("Which pair of lenses did you prefer? The first pair, the second pair). Reported per lens. Measured at completion of V5 (lens pair two evaluation). Both lenses have been worn. Total time since base line is 34-48 days.
