Selected segments from a 2.5 minute animation that highlights the features and benefits of a new biomimetic technology that combines a biomimetic surface and unique lens chemistry to help resist bacteria and lipid deposits. Durable enough to deliver comfort for a full 30 days of wear, the TOTAL30 contact lens surface mimics the softness of the human cornea, keeping the eyes healthy with high oxygen permeability and superior lens surface moisture stability.
Unique challenges for this project included building a microworld of corneal epithelium and glycocalyx – a network of proteoglycans that covers epithelia of the eye – as well as construction of a polymer nanofiber “brush” that moves in a constant, dynamic, undulating motion like that of the corneal surface.
Another critical aspect was showcasing how these two dynamic surfaces (glycocalyx and polymer nanofibers) come together to form a layer of surface protection with the tear film. This biomimetic design provides a naturally clean, lubricious surface that is as soft as the human cornea, yet durable enough to last through 30 days of cleaning and maintenance.
