入选标准
- •Potential subjects must satisfy all of the following criteria to be enrolled in the study:
- •Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
- •Appear able and willing to adhere to the instructions set forth in this clinical protocol.
- •Be between 18 and 39 (inclusive) years of age at the time of screening.
- •By self-report, habitually wear spherical soft silicone hydrogel contact lenses in both eyes in a daily wear or daily disposable wear modality (i.e. not extended wear modality). Habitual wear is defined as a minimum of 6 hours of wear per day, for a minimum of 5 days per week during the past 30 days.
- •Possess a wearable pair of spectacles that provide correction for distance vision.
- •The spherical equivalent of the subject's vertex-corrected distance refraction must be between -1.00 and -6.00 DS (inclusive) in each eye.
- •The magnitude of the cylindrical component of the subject's vertex-corrected distance refraction must be between 0.00 and 1.00 DC (inclusive) in each eye.
- •The best corrected, monocular, distance visual acuity must be 20/25or better in each eye.
排除标准
- •Potential subjects who meet any of the following criteria will be excluded from participating in the study:
- •Be currently pregnant or lactating.
- •Be currently using any ocular medications or have any ocular infection of any type.
- •By self-report, have any ocular or systemic disease, allergies, infection, or use of medication that the investigator believes might contraindicate or interfere with contact lens wear, or otherwise compromise study endpoints, including infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive disease (e.g., Human Immunodeficiency Virus [HIV]), autoimmune disease (e.g. rheumatoid arthritis, Sjögren's syndrome), or history of serious mental illness or seizures. See section 9.1 for additional details regarding excluded systemic medications.
- •Have habitually worn rigid gas permeable (RGP) lenses, orthokeratology lenses, or hybrid lenses (e.g. SynergEyes, SoftPerm) within the past 6 months.
- •Be currently wearing monovision or multifocal contact lenses.
- •Be currently wearing lenses in an extended wear modality.
- •Have participated in a contact lens or lens care product clinical trial within 14 days prior to study enrollment.
- •Be an employee (e.g., Investigator, Coordinator, Technician) or immediate family member of an employee (including partner, child, parent, grandparent, grandchild or sibling of the employee or their spouse) of the clinical site.
- •Have clinically significant (grade 3 or higher on the FDA grading scale) slit lamp findings (e.g., corneal edema, neovascularization or staining, tarsal abnormalities or bulbar injection) or other corneal or ocular disease or abnormalities that the investigator believes might contraindicate contact lens wear or may otherwise compromise study endpoints (including entropion, ectropion, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, moderate or above corneal distortion, herpetic keratitis). (Specify method of determination if needed).
- •Have a history of strabismus or amblyopia.
- •Have fluctuations in vision due to clinically significant dry eye or other ocular conditions.
- •Have had or have planned (within the study period) any ocular or intraocular surgery (e.g., radial keratotomy, PRK, LASIK, iridotomy, retinal laser photocoagulation, etc.).
结局指标
主要结局
Overall Quality of Comfort Score
时间窗: 2-Week Follow-up
Overall quality of comfort score was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120. The average CLUE comfort score for each lens type was reported.
Overall Quality of Vision Score
时间窗: 2-Week Follow-up
Overall quality of vision score was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120. The average CLUE vision score for each lens type was reported.
