Ex vivo eye model system for screening ocular products

Abstract

The present disclosure is directed to an ex vivo eye model system for screening ocular products with programmable blinking and tear flow control. In one example implementation, the ex vivo eye model system includes an eyeball core, an upper and lower eyelid frame, a servo, and a tear fluid delivery system. The eyeball core may be configured to hold a biological eye. The upper eyelid frame and the lower eyelid frame may be configured to replicate natural blinking actions and interact with the biological eye. The servo may be operatively connected to the upper eyelid frame and the lower eyelid frame. The servo may be configured to simulate controlled blinking actions by actuating the upper eyelid frame and the lower eyelid frame to move corresponding eyelid membranes of the biological eye. The tear fluid delivery system configured to deliver a fluid to an ocular surface of the biological eye.
