Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a pilot evaluation to assess the feasibility of using ultra-high resolution optical coherence tomography (OCT) to image and 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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subject A (Neophytes)

Subjects will wear the Marketed Contact Lens 1, Marketed Contact Lens 2, Marketed Contact Lens 3, and Marketed Contact Lens 4 for a 6-hour period in a bilateral and random fashion, with a washout period of one week between lenses. Each subject will randomly be assigned to one of four unique sequences of a 4 x 4 crossover design. A block size of two sequences will be used.

Group Type ACTIVE_COMPARATOR

Marketed Contact Lens 1

Intervention Type DEVICE

Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

Marketed Contact Lens 2

Intervention Type DEVICE

Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

Marketed Contact Lens 3

Intervention Type DEVICE

Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

Marketed Contact Lens 4

Intervention Type DEVICE

Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

Subject B (Habitual Lens Wearers)

Subjects will wear the Marketed Contact Lens 1, Marketed Contact Lens 2, Marketed Contact Lens 3, and Marketed Contact Lens 4 for a 6-hour period in a bilateral and random fashion, with a washout period of one week between lenses. Each subject will randomly be assigned to one of four unique sequences of a 4 x 4 crossover design. A block size of two sequences will be used.

* The subject must have best corrected visual acuity of 20/25 or better in each eye.
* The subject must be either a neophyte or a habitual and adapted wearer of soft contact lenses in both eyes.
* The subject must have normal eyes (i.e., no ocular medications or infections of any type).
* The subject must demonstrate adequate mobility and 20/30 vision oculus dexter (OD) and oculus sinister (OS) with the study contact lenses.

Exclusion Criteria

* Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).
* Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
