Trial Outcomes & Findings for A Comparison of Silicone Hydrogel Contact Lenses: AIR OPTIX® COLORS Versus AIR OPTIX® AQUA (NCT NCT01635920)

NCT ID: NCT01635920

Last Updated: 2014-03-28

Results Overview

Lens fit was assessed by the investigator for each eye using a biomicroscope (slit lamp), which magnifies the appearance of the contact lens on the participant's eye. Lens fit was graded on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight. "Same fit" was defined as an eye that achieved an acceptable or optimal overall lens fit with the study lens, that was also within one grade of the value observed on the same eye with the habitual lens at the baseline visit.

PRIMARY outcome

Timeframe: Up to Day 28

Population: ITT: All enrolled and dispensed participants who had at least one study visit after being dispensed with study lenses (N=125,126). No imputation was used for the missing values. Here, "n" is the number of participants with non-missing values at the specific time point for each arm group, respectively.

Lens fit was assessed by the investigator for each eye using a biomicroscope (slit lamp), which magnifies the appearance of the contact lens on the participant's eye. Lens fit was graded on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight. "Same fit" was defined as an eye that achieved an acceptable or optimal overall lens fit with the study lens, that was also within one grade of the value observed on the same eye with the habitual lens at the baseline visit.

SECONDARY outcome

Timeframe: Up to Day 28

Population: ITT: All enrolled and dispensed participants who had at least one study visit after being dispensed with study lenses (N=125,126). No imputation was used for the missing values. Here, "n" is the number of participants with non-missing values at the specific time point for each arm group, respectively.

Overall comfort, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.
