Prospective, randomized, masked (reading center), controlled pivotal study of Ocular Bandage Gel (OBG) vs. a bandage contact lens (BCL) in subjects who have undergone bilateral photorefractive keratectomy (PRK).
This is a prospective, randomized, masked (reading center), controlled pivotal study of Ocular Bandage Gel (OBG) vs. a Bandage Contact Lens (BCL) in subjects who have undergone bilateral photorefractive keratectomy (PRK). Study subjects will be evaluated and, if eligible following PRK, will receive the study treatment in a 1:1 randomization with both eyes receiving the same treatment. Sites will capture the time that PRK surgery OU is completed. Sites will enroll eligible subjects and randomly assign a subject to Treatment Group (OBG) or Control Group (BCL). One eye will be randomized as the designated "study eye" for statistical purposes. The reading center will be masked as to the randomization assignments. Both eyes will receive the same randomized assignment and both eyes of each subject will be evaluated at all timepoints. The defect in both eyes of all subjects will be measured starting at Day 2 (48 hours after PRK). The slit lamp photos are to be collected at 48 hours (±1 hour) from PRK completion in both eyes. The BCL in the Control Group eyes will be removed daily starting at Day 2 for slit lamp photos. Slit lamp measurements, as well as photography of the epithelial defect (without and with fluorescein), will be taken of both eyes of all subjects. Photos will be evaluated by a masked reading center.
|Experimental: Ocular Bandage Gel (OBG)
Cross-linked Hyaluronic Acid 0.75%, regulated through CDRH (device). EyeGate Ocular Bandage Gel will be applied topically to both eyes (OU) four times a day. Ocular Bandage Gel use is discontinued once complete re-epithelialization has occurred in that eye.
Device: Ocular Bandage Gel (OBG)
A modified form of the natural polymer hyaluronic acid, which is a gel that possesses unique physical and chemical properties such as hydrating and healing when applied to the ocular surface. The ability of CMHA-S to adhere longer to the ocular surface, resist degradation and protect the ocular surface makes it well-suited for treating various ocular surface injuries including surgical trauma.
|Other: Bandage Contact Lens (BCL)
standard-of-care post-operative intervention following PRK. BCL (Acuvue® Oasys plano lens) applied OU. Bandage contact lens use is discontinued once complete re-epithelialization has occurred in that eye.
Device: Bandage Contact Lens (BCL)
A bandage contact lens protects an injured or diseased cornea from the mechanical rubbing of the blinking eyelids, therefore allowing it to heal. It is a normal (usually soft, but not always) contact lens has no power. It is not intended to improve your vision.
