Evaluating Accommodative Responses of Soft Contact Lenses for Myopia Control

Completed · Not applicable

Conditions studied: Visual Acuity

In brief

This is a bilateral, non-dispensing, randomized, controlled, double-masked, 7x7 cross-over study. Each subject will be bilaterally fitted with one of the 7 test articles in each of the 7 periods for a total of four visits. Up to two lens types will be fit at each of the four study visits.

• Adult subjects (≥18 years old) and parent(s) or legal guardian(s) of pediatric subjects must 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.
• Between 7 and 25 years of age (inclusive).
• Have normal eyes (i.e., no ocular medications or infections of any type).
• Vertex-corrected distance subjective best-sphere refraction must be between -0.75D and -5.00D (inclusive) in each eye.
• Cylindrical refraction must be 1.00D or less in each eye, by subjective sphero-cylindrical refraction.
• Have sphero-cylindrical best-corrected visual acuity of 20/25 or better in each eye.

You may not qualify if…

• Potential subjects who meet any of the following criteria will be excluded from participating in the study:
• Currently pregnant or lactating.
• Any systemic allergies, infectious disease (e.g., hepatitis, tuberculosis, HIV), autoimmune disease (e.g., rheumatoid arthritis), or other diseases, by self-report, which are known to interfere with contact lens wear and/or participation in the study.
• Use of systemic medications (e.g., chronic steroid use) that are known to interfere with contact lens wear and/or participation in the study. Specifically, any chronic (3 months or more) or short-term (within 7 days from enrollment) use of oral agents with antimuscarinic properties.
• Any current use of ocular topical medication (occasional use of re-wetting drops is allowed). Specifically, any use of topical agents with anti-muscarinic properties within 21 days from enrollment.
• Any previous or planned ocular or intraocular surgery, including refractive surgery.
• Participation in any contact lens or lens care product clinical trial within 7 days prior to study enrollment.
• Current or recent (within 30 days from enrollment) rigid lens wearers.
• History of orthokeratology treatment.
• Any known hypersensitivity or allergic reaction to EyeCept® (or sponsor approved equivalent) Rewetting Drop Solution.
• Employees or their children/relatives of investigational clinic (e.g., Investigator, Coordinator, Technician).
• Any ocular allergies, infections or other ocular abnormalities that are known to interfere with contact lens wear and/or participation in the study. This may include, but not be limited to, aphakia, uveitis, ocular hypertension, glaucoma, severe keratoconjunctivitis sicca, history of recurrent corneal erosions, keratoconus, keratoconus suspect, pellucid marginal degeneration, entropion, ectropion, extrusions, chalazia, and recurrent styes.
• Any Grade 3 or greater slit lamp findings (eg, edema, corneal neovascularization, corneal staining, tarsal abnormalities, and conjunctival injection) on the FDA scale.
• Any ocular abnormality that is contraindicated contact lens wear.
• Any corneal scar within central 5mm
• Binocular vision abnormality, intermittent strabismus or strabismus.
• Any corneal distortion resulting from ocular diseases or previous hard or rigid gas permeable contact lens wear.
