Clinical Trial Summary

The purpose of this study was to evaluate the cosmetic performance of AIR OPTIX® COLORS contact lenses compared to FRESHLOOK® COLORBLENDS contact lenses in habitual FRESHLOOK® COLORBLENDS contact lens wearers.


Description:

In this non-dispensing trial, each participant wore 4 pairs of color contact lenses (gray, blue, green, hazel) sequentially for less than 10 minutes each in a contralateral fashion (test lens in one eye, control lens in the other eye). Randomization took place for each of the 4 pairs of lenses as to which eye (left or right) wore the test and which wore the control. Participants were selected based on eye color (dark vs light/medium). The primary analysis population (AP1) was pre-specified as participants of any eye color who habitually wore FRESHLOOK® COLORBLENDS lenses in one of the four colors tested in this trial. Pair 1 lenses were dispensed per the participant's habitual lens color.

- Habitually wear FRESHLOOK® COLORBLENDS lenses at least two days per week.

- Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

- Eye injury or surgery within twelve weeks of enrollment in this trial.

- Pre-existing ocular irritation that would preclude contact lens fitting.

- Currently enrolled in any clinical trial.

- Evidence of systematic or ocular abnormality, infection, or disease which is likely to affect successful wear of contact lenses or use of accessory solutions as determined by the investigator.

- Any use of medications for which contact lens wear could be contraindicated as determined by the investigator.

- Other protocol-defined exclusion criteria may apply.

Outcome

Type Measure Description Time frame Safety issue
Primary Overall Preference The participant compared Pair 1 study lenses on eye and indicated overall preference using a 4-point Likert scale (prefer lens in the left eye, prefer lens in the right eye, no preference, or both eyes are equal). Overall preference is reported as the percentage of participants who preferred the study lens. Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2-10 minutes after lens insertion No
Primary Initial Comfort Preference The participant compared the initial comfort (way it feels) of Pair 1 study lenses and indicated preference using a 4-point Likert scale (prefer lens in the left eye, prefer lens in the right eye, no preference, or both eyes are equal). Initial comfort preference is reported as the percentage of participants who preferred the study lens. Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2 minutes after lens insertion No
Primary Appearance Preference The participant compared the appearance (way it looks) of Pair 1 study lenses on eye and indicated preference using a 4-point Likert scale (prefer lens in the left eye, prefer lens in the right eye, no preference, or both eyes are equal). Appearance preference is reported as the percentage of participants who preferred the study lens. Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2-10 minutes after lens insertion No
Primary Subjective Rating of Initial Comfort The participant compared the initial comfort (way it feels) of Pair 1 study lenses and rated initial comfort using a 10-point scale (1=poor, 10=excellent). Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2 minutes after lens insertion No
Primary Percent Positive Responses: Cosmetic Appearance (Strongly Agree, Agree) The participant compared the cosmetic appearance of Pair 1 study lenses on eye and answered 9 appearance-related questions using a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree). The combined percentage of the top two responses (strongly agree, agree) is reported for each question. Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2-10 minutes after lens insertion No
Primary Percent Positive Purchase Intent (Definitely Would Buy, Probably Would Buy) The participant compared Pair 1 study lenses and indicated purchase intent by answering the following question, "Assuming these lenses were at a price you would expect to pay, how likely would you be to purchase these lenses?" using a 5-point Likert scale (definitely would buy, probably would buy, might or might not buy, probably would not buy, definitely would not buy). The combined percentage of the top two responses (definitely would buy, probably would buy) is reported. Each lens was assessed separately. This outcome measure was pre-specified for Analysis Population 1 (AP1). Day 1, 2-10 minutes after lens insertion No
