A Clinical Comparison of Three Contact Lens Care Systems and Their Effect on Contact Lenses

November 15, 2016 updated by: Alcon Research
The purpose of this study was to evaluate the clinical performance of three differing contact lens care solutions when used in conjunction with three contact lenses.

Study Overview

Detailed Description

This study was conducted as three separate studies based on the contact lens brand dispensed. In each study, the contact lens was evaluated in conjunction with three solutions: Opti-Free Replenish, ReNu MultiPlus, and Clear Care. The total enrollment number of 75 represents a combined enrollment of the three studies, with some subjects participating in more than one study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modulus
Time Frame: 2 weeks
Modulus is a measure of the stiffness of a contact lens material. Modulus is determined from the slope of the stress-strain curve created during tensile tests conducted on a sample of the material. Modulus is measured in mega Pascals (MPa). A higher modulus indicates a stiffer contact lens.
2 weeks
Bulbar hyperemia
Time Frame: 2 weeks
Bulbar hyperemia is the injection (or redness) of the blood vessels in the tissues overlaying the white of the eye. Bulbar hyperemia is measured on a 0-4 scale, with 0=none, 1=trace, 2=mild, 3=moderate, and 4=severe. Half-grades are allowed.
2 weeks
Corneal staining type
Time Frame: 2 weeks
An ophthalmic dye is used to highlight dead or degenerated corneal epithelial cells. The type of staining is measured over the five sectors of the cornea on a 0-4 scale, where 0=none, 1=micropunctate, 2=macropunctate, 3=coalesced macropunctate, and 4=patch (1mm). The five sectors are averaged to give a single score.
2 weeks
Upper palpebral roughness
Time Frame: 2 weeks
The roughness of the inner lining of the upper eyelid is measured on a 0-4 scale, where 0=uniform appearance, 1=trace, 2=mild, 3=moderate, and 4=severe. Half grades are allowed.
2 weeks
High contrast visual acuity
Time Frame: 2 weeks
High contrast visual acuity is a measure of the clearness of vision with full room illumination. Visual acuity is measured with a computer-generated, high contrast logMAR (logarithm minimum angle of resolution) chart.
2 weeks
End of day comfort
Time Frame: 2 weeks
As assessed by the subject as a measure of the comfort of the contact lenses at the end of an average day. End of day comfort is recorded on an 11-point scale where 0=poor and 10=excellent.
2 weeks
