- Conditions
- Myopia
- Registration Number
- NCT04492397
- Lead Sponsor
- Coopervision, Inc.
- Brief Summary
The objective of the study is to evaluate and compare the performance of study test lens to study control lens, when worn on a daily disposable modality over a period of approximately one week each
- Detailed Description
The study is a prospective, double masked (investigator and participant), bilateral, randomized,one week cross-over dispensing study, which evaluates the study test lens and control lens.
Recruitment & Eligibility

- All
- Target Recruitment
- 35
- Is at least 17 years of age and has full legal capacity to volunteer;
- Has read and signed an information consent letter;
- Is willing and able to follow instructions and maintain the appointment schedule;
- Habitually wears soft contact lenses in daily wear, for minimum of 6-months;
- Is correctable to a visual acuity of 20/40 or better (in each eye) with the study lenses;
- Has an astigmatism of ≤ 1.00 D in subjective refraction;
- Can be fit with study contact lenses with a power between -2.00 and -5.00 DS;
- Demonstrates an acceptable fit with the study lenses;
- Habitually wears single vision soft contact lenses for at least 8 hours per day, 5 days a week, and is willing to wear contact lenses for at least 12 hours a day in the study.
- Is participating in any concurrent clinical or research study;
- Has any known active* ocular disease and/or infection;
- Has a systemic condition that in the opinion of the investigator may affect a study outcome variable;
- Is using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable;
- Has known sensitivity to the diagnostic pharmaceuticals to be used in the study;
- Is pregnant, lactating or planning a pregnancy at the time of enrolment because the associated hormonal changes cause changes in the tear layer which impact contact lens comfort. Verbal confirmation at the screening visit is sufficient;
- Is aphakic;
- Has undergone refractive error surgery;
- Is an employee of the Centre for Ocular Research & Education;
- Has participated in the BOXER (i.e. EX-MKTG-107, phases 1 or 2) or BASSET (EXMKTG-113) Study;
- Has participated in any clinical trials within a week prior to the study.

- CROSSOVER
- Primary Outcome Measures
Name Time Method Overall Lens Fit Acceptance 1 week Overall fit acceptance (0-4, 0.50 steps) (0 - lens should not be worn at all,1 - Borderline but unacceptable, 2 - Minimally acceptable, 3 - Not perfect but OK to dispense, 4 - Perfect)
- Secondary Outcome Measures
Name Time Method Lens Centration 1 week Lens Centration was measured on a scale (0-3) (0 = "Optimally centered", 1 = "Slightly decentered", 2 = Moderate decentration but not encroaching limbus, 3 = "Excessive \& occasionally encroaching limbus")
Post-blink Movement 1 week Post-blink lens movement was measured using an eyepiece reticule while viewing the contact lens in-vivo at 8x magnification in primary gaze, in 0.1mm steps
Push-up Tightness 1 week Push-up tightness in primary gaze measured on a scale (0-100, 5% steps) (0% = falls from cornea without lid support, 50% = optimum and 100% = no movement)
