Overview
Brief Summary
This is a multi-site, randomized, double-masked, contralateral, 2 treatment x 2 period crossover, dispensing, five-visit study to gain clinical insights of the study lenses and solutions.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Potential subjects must satisfy all of the following criteria to be enrolled in the study:
- •Subjects must be 18-69 years of age (inclusive).
- •Subjects must be habitual disposable hydrogel or silicone hydrogel (1-day, 2-week, or monthly replacement schedule) soft lens wearer in both eyes. Habitual is defined as at least one (1) month of contact lens wear where the lenses are worn for a minimum of six (6) hours per day and a minimum of five (5) days per week.
- •Subjects must have best corrected visual acuity of 20/25 (Snellen or equivalent) or better in each eye.
- •The subject's refractive sphere (vertexed) must be between -1.00 and -6.00 D in each eye.
- •The subject's refractive cylinder must be less than or equal to -1.00 D in each eye.
- •The subject must have normal eyes (i.e., no ocular medications or infections of any type).
- •Subjects must possess a functional/usable pair of spectacles and bring them to the visit (only if applicable - to the investigators discretion).
- •Subjects must read, understand, and sign the Statement of Informed Consent.
- •Subjects must appear able and willing to adhere to the instructions set forth in this clinical protocol.
Exclusion Criteria
- •Potential subjects who meet any of the following criteria will be excluded from participating in the study:
- •Currently pregnant or breast-feeding.
- •Any ocular or systemic allergies or disease which may interfere with contact lens wear (at the discretion of the investigator).
- •Any systemic disease, autoimmune disease, or use of medication which may interfere with contact lens wear (at the discretion of the investigator).
- •Any infectious diseases (e.g. hepatitis, tuberculosis) or a contagious immunosuppressive disease (eg, HIV), by self-report.
- •Current habitual use of Restasis, Xiidra, ocular steroids, or any medication (RX or OTC) that may interfere with contact lens wear (at the discretion of the investigator).
- •Grade 2 or greater corneal staining or conjunctival injection on the FDA scale.
- •Clinically significant (Grade 3 or greater on the FDA scale) corneal edema, corneal vascularization, or any other abnormalities of the cornea (excluding corneal staining) which would contraindicate contact lens wear.
- •Clinically significant (Grade 3 or greater on the FDA scale) tarsal abnormalities which might interfere with contact lens wear.
- •Any active ocular abnormalities/conditions that may interfere with contact lens wear (at the discretion of the investigator).
Outcomes
Primary Outcomes
Subject Comfort
Time Frame: Up to 2-Hours Post Lens Fitting
Subjective assessment of initial comfort was conducted using Visual Analogue Scale (VAS) of comfort. VAS of comfort consists of a vertical line which represents continuous scale from 0 (extremely uncomfortable) to 100 (extremely comfortable). VAS comfort was measured at 1-min, 5-min, 45-min, and 2-hours post-fit. The average comfort score for each solution was reported. This is a contralateral crossover, subject used the revitalens solution in one eye throughout the entire study therefore there are twice as many observations for revitalens compared to the other solutions.
