This is a single-site, two-visit, contralateral, non-dispensing, randomized, controlled and subject-masked study to measure potential benefits of the new UV blocker.
This is an unmasked, non-randomized, single arm, stratified, dispensing investigation of symptomatic and asymptomatic subject populations. Subjects will be assigned to a single study lens type to be worn bilaterally for approximately 4 weeks followed by no contact lens wear for 1 week.
Dispensing Study for the Phenacite Project. The investigational test lens was not the final optical design and the study was not used for design validation.
The purpose of the study is to compare the investigational contact lens to a marketed contact lens. The study results were not used for design validation of investigational contact lens,
The primary objective of thes study is to confirm that the ocular response to the Test lenses are similar to those of the Control lenses when used in a 1 week planned replacement, daily wear modality over a 1-month period.
Testing the Safety and Acceptability of Using a Rewetting Drop with Contact Lenses
The purpose of this study is to evaluate and compare the clinical performance of two toric contact lenses amongst 110 subjects, 2-week, single masked (subject), daily wear, randomized, bilateral, crossover study; 4 weeks duration. Hypotheses include equal or better performance of the test lens over the control lenses for comfort, vision, and toric fit characteristics as well as corneal integrity
To compare the safety and efficacy of the CVI silicone-hydrogel lens worn on an extended wear basis for a period of up to 7 days and 6 nights with the Acuvue 2 soft contact lenses.
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.
The main objective of this study is to demonstrate acceptable safety and effectiveness (performance) of comfilcon A Sphere, Toric, Multifocal, Toric Multifocal and Energys lenses, when used in the general population.
The primary purpose of this study is to demonstrate noninferiority in the visual acuity at distance when wearing PRECISION1™ for Astigmatism (P1fA) soft contact lenses compared to another commercially available, soft toric contact lens, MyDay® toric (MDT).
The purpose of this study is to compare the clinical performance of DAILIES TOTAL1 ( DT1) contact lenses with Infuse contact lenses.
The purpose of this study is to evaluate the overall performance of PRECISION1™ contact lenses when compared to INFUSE™ contact lenses.
The purpose of this study is to compare the clinical performance of PRECISION1™ for Astigmatism (P1fA) contact lenses with 1-DAY ACUVUE MOIST® for ASTIGMATISM (AMfA) contact lenses.
The purpose of this study is to compare the results of vision tests that are algorithmically derived and delivered through a virtual reality headset with those delivered through the existing technology standards (eg. Humphrey for field tests). Tests that the researchers will be conducting include vision field perimetry, Amsler, acuity chart, contrast- sensitivity and currently used office tests.
The primary objective of this study is to evaluate the overall performance of an investigational silicone hydrogel lens when compared to ACUVUE OASYS® with HYDRACLEAR® PLUS (AOHP).
The primary objective is to evaluate corneal staining observed after 2 hours of wear with contact lenses with investigational coating against PureVision™ lenses, all pre-cycled with OPTI-FREE® RepleniSH® multi-purpose disinfection solution.
