The purpose of this study is to compare two marketed contact lens care solutions in regards to comfort and ocular health.
The purpose of this study is to compare the clinical performance of three contact lens care products, and to compare their effects on contact lenses.
The principal aim of this project is to determine the time course of development of contact lens and contact lens case contamination during daily wear of silicone hydrogel lenses. The secondary aim of the study is to determine whether the time course of development of contact lens and contact lens case contamination varies between two different contact lens care systems.
Three arm study comparing three novel contact lens solutions.
This will be a controlled and randomized, single-masked, crossover study in which 48 subjects will use the Biofinity Contact Lens (comfilcon A) with each of the two lens care products ('solutions'), (Synergi and Biotrue Multi-purpose Solution) for one month each. Follow-up visits for each solution will take place at one week, two weeks and four weeks: with a one-week 'wash-out' period between the solutions. Key outcome measures for this study include biomicroscopic and subjecti...
The primary purpose of this study is to investigate the performance of contact lens maintenance systems when used with silicone hydrogel contact lenses during daily wear over a period of 1 month.
The objective of this study is to compare the short-term clinical response to all combinations of two lens types: fanfilcon A and comfilcon A with two care systems: Hy-Care and Lite. The primary variables of interest are short-term biomicroscopy signs. Other variables of interest include subjective response and visual performance.
The purpose of this study is to compare Opti-Free III lens care product to Opti-Free Plus® lens care product for corneal staining with Acuvue® Oasys® contact lenses. The contact lenses will be soaked in the lens care products for 24-48 hours prior to wear.
This is a pilot evaluation to assess the feasibility of using novel imaging process to characterize lens edge and limbal epithelial thickness profile; lens movement with gaze and blink; and conjunctival microvasculature including fractal analysis of microvascular perfusion maps and blood flow velocity.
The purpose of the study is to evaluate and compare, on a daily wear basis, the performance of two contact lens care solutions when used with silicone hydrogel soft contact lenses with regards to comfort and dryness symptoms.
The purpose of this study is to evaluate the reduction of contact lens-related dryness symptoms when symptomatic weekly/monthly contact lens wearers are switched to DAILIES AquaComfort Plus lenses for a two-week period using composite scores on the Contact Lens Dry Eye (CLDE) Questionnaire.
The purpose of this study is to compare the wettability of contact lenses disinfected with three marketed contact lens care solutions.
Adaptive, randomized, subject-masked, dispensing study to evaluate the short-term, clinical performance of two FDA-approved contact lens.
The purpose of this study is to evaluate CLEAR CARE® PLUS (CCP) compared to non-HYDRAGLYDE® multipurpose contact lens solutions in presbyopes currently wearing soft contact lenses and experiencing symptoms of dryness.
To evaluate the effect of lens properties of the different types of contact lenses on the ocular health of existing contact lens wearers when used in an extended wear modality of up to seven days/six nights.
This study seeks to evaluate the clinical and subjective performance of a new daily disposable soft contact lens.
Contact lens induced dry eyes leads to lens intolerance and discontinuation. Incidence of dry eye in contact lens wearer is significantly higher in Asian population compared to other ethnic group considering Asian has lower tear break up time. Disruptions of tear integrity in contact lens wearer will further exacerbate the condition. Factors for successful contact lens fitting derive from the biocompatibility of lens material, lens design and stability of tear film in front of ...
The purpose of this trial is to evaluate the factors affecting comfortable contact lens wear and how those factors affect contact lens replacement frequency.
The most common reason for contact lens discontinuation is contact lens discomfort. The investigators believe that inflammation plays a role in contact lens discomfort and the use of lifitegrast 5% ophthalmic solution may reduce end of the day contact lens discomfort. This study will enroll 21 contact lens users who will be receiving lifitegrast 5% ophthalmic solution and monitor the contact lens discomfort for a 8 week period while.
The objective of this study is to evaluate the safety and effectiveess of ASP-57 Multi-Purpose contact lens solution (Test) compared to ReNu® Multiplus Contact Lens Solution (Control) when used by habitual contact lens wearers to bilaterally clean and disinfect their contact lenses for approximately 3 months (12 weeks).
The purpose of this study is to evaluate the effect of a multi-focal contact lens on symptomatic patients.
The purpose of this study is to assess the lens and lens case microbial colonization associated with marketed care solutions used by experienced soft lens wearers.
The purpose of this study is to evaluate the clinical performance of two daily disposable silicone hydrogel contact lenses. One of these lenses, the 'test' lens is an investigational product. This means that it has not yet been approved for commercial use and is not available for sale. The other lens (control) is a commercially available contact lens. The results of this study will be analysed to determine how the 'test' lens compares with the 'control' lens. The control lens ...
The purpose of this study is to compare visual acuity and redness of eyes between a new contact lens and an already marketed contact lens.
To evaluate safety with the use of Systane Ultra in contact lens wearers. A comparison to a currently marketed contact lens rewetting drop will be included as a control.
