Trial Outcomes & Findings for Comparison of Lens Fit and Lens Power of a New Contact Lens to Two Marketed Contact Lenses in a Population of Soft Contact Lens Wearers (NCT NCT01244529)
NCT ID: NCT01244529
Last Updated: 2018-06-19
Results Overview
Investigator evaluated as acceptable (centered/slightly decentered) or unacceptable (substantially decentered). Number of eyes in each category will be reported by lens. This is an aggregate reporting of the lenses, combining the different base curves into a category by lens type. This is done per protocol, due to this primary outcome not being stratified by base curve.

All Subjects
n=41 Participants
All subjects who where enrolled wore all intervention lenses throughout the course of the study. The specific lenses used include the following: senofilcon A (control) soft contact lens with 8.8 base; senofilcon A (control) soft contact lens with 8.4 base curve; galyfilcon A (control) soft contact lens with 8.7 base curve; galyfilcon A (control) soft contact lens with 8.3 base curve; galyfilcon A Plus (test) soft contact lens with 8.7 base curve; galyfilcon A Plus (test) soft contact lens with 8.3 base curve.

PRIMARY outcome
Timeframe: after 15 minutes of contact lens wearPopulation: Analysis was on those completed subjects who were enrolled, randomized, and assigned to a study arm.
Investigator evaluated as acceptable (centered/slightly decentered) or unacceptable (substantially decentered). Number of eyes in each category will be reported by lens. This is an aggregate reporting of the lenses, combining the different base curves into a category by lens type. This is done per protocol, due to this primary outcome not being stratified by base curve.

PRIMARY outcome
Timeframe: after 15 minutes of contact lens wearPopulation: Analysis was on those completed subjects who were enrolled, randomized, and assigned to a study arm.
Investigator evaluated as acceptable (minimal or moderate movement) or unacceptable (insufficient or excessive movement). Percent of eyes in each category will be evaluated.

PRIMARY outcome
Timeframe: after 15 minutes of contact lens wearPopulation: Analysis was on those completed subjects who were enrolled, randomized, and assigned to a study arm.
Investigator evaluated lens fit using a six point scale: 5-optimal...3-borderline acceptable...2-unacceptable. Percent of eyes in each category will be evaluated.

SECONDARY outcome
Timeframe: after 15 minutes of contact lens wearPopulation: Analysis was on those completed subjects who were enrolled, randomized, and assigned to a study arm.
The lens power fit of test lenses will be compared to control lenses to determine if the power matches. Percent of eyes with exact power fit will be evaluated.
