Optometry Today (OT), in partnership with Alcon and the AOP, are pleased to provide this webinar.
This lecture will present current research on contact lens interactions with the ocular tear film and will focus on in vitro evidence suggesting that surface gel layers may reduce shear stress and discomfort during contact lens wear - one of the leading causes of dropout. The aim of this lecture is to educate clinical professionals on the principles of biotribology and the materials science of surface gel layer in the management of contact lens wearers.
Learning outcome
- Practitioners will recognise the factors that influence contact lens interaction with the tear film and the impact this can have on discomfort and subsequent dropout.

Dr Angela Pitenis
Angela is assistant professor in the materials department at the University of California.Her research interests are focused on understanding the interfacial phenomena, tribology, and interactions of surfaces of soft, biological, and bio-inspired materials. Angela’s work revealed that the tribology of PTFE (Teflon) was actually driven by interactions with water vapour and oxygen, and that many of the amazing attributes of a material regarded as the world’s most inert were actually driven by tribochemistry.
Recently, Angela’s work has focused on the interactions between surfaces of hydrogels and ocular epithelia. This work has led to the development of soft, low-friction surface gel layers applied to medical devices such as contact lenses. Angela has roughly 50 publications, holds three patents and leads a multidisciplinary team of materials scientists, molecular biologists, and chemical engineers at the University of California.
