Filter by:Approximately 30 soft toric contact lens adapted subjects will be enrolled in this feasibility, bilateral, randomized, double masked (subject and investigator masked), repeated measures insertion study. All subjects will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If subjects satisfy all eligibility criteria and none of the exclusion criteria, subjects will have study lenses inserted in random, successive order according to unique randomization schedules that will be provided to each Investigator.
Experienced soft contact lens wearing subjects will be enrolled in this 1-week, post-market, bilateral, repeated measures, dispensing study. All subjects will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If subjects satisfy all eligibility criteria and none of the exclusion criteria, subjects will be fit and dispensed study lenses. If unsuccessful in the dispensed lenses, additional lenses may be trialed. Once vision and lens fit are determined to be acceptable, eligible subjects will wear study lenses in both eyes for at least 8 hours per day (with the exception of the follow-up visits where the lenses should be worn for a minimum of 2 hours), for approximately 1 week (7 days +/-3 days). Measurements will be taken at the insertion visit and at the 7-day follow-up visit.
The purpose of this study is to assess long term performance and safety of AONDA in a real world setting when worn as daily wear or continuous wear for vision correction. This study will be used to support AONDA's marketability in Europe and other locations.
The purpose of this study is to assess the clinical performance of two reusable silicone hydrogel contact lenses when worn on a daily wear basis.
The purpose of this clinical trial was to evaluate the clinical performance of a manufacturing process on a frequent replacement multifocal contact lens.
Approximately 340 participants (680 eyes) will be enrolled in this three-month, two-arm, 1:1 randomized, parallel-group, bilateral, double-masked study at approximately 22 investigative sites in the United States. Participants will be required to wear dispensed study lenses on a daily wear basis for three months with scheduled in-office replacement of study lenses at the 1-Month and 2-Month Follow-Up Visits.
The purpose of this clinical trial is to evaluate the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in an extended wear modality.
The purpose of this study was to compare the clinical performance of the new DAILIES® AquaComfort PLUS® FreshTech (DACP FreshTech) contact lenses to an already marketed daily disposable contact lens, DAILIES® AquaComfort PLUS® (DACP).
To evaluate and compare the performance of a new contact lens to a marketed contact lens.
This study will serve to evaluate and compare the performance of two new lenses to a marketed lens.
