    In this edition, we will explore the recent developments in eye tracking technology, discussing both the clinical and commercial applications of the technique. First, we investigate the future of contact lens material technology and listen in to a debate between leading experts in the contact lens field.

      Learning objectives

      • 1.1.2 Understand how modern research into protein deposition and denaturation may influence the likelihood and course of microbial infection of the anterior ocular surface with particular reference to contact lens wearers.
      • 2.5.3 Understand the nature of two new developments (eye tracking technology and contact lens disinfection developments) in eye assessment and how they may influence future eye examination.
      • 5.2.1 Understand the nature of protein deposition and denaturation to better understand how developments here may lead to more effective disinfection and greater patient comfort.
      • 8.1.1 Understand the potential for eye tracking technologies to enhance and build upon current ocular movement techniques (cover test, motility) to assess anomalies of binocular vision.

        Unit 1 - New thinking in avoiding contact lens related infection (~23 mins)

        Professor Philip Morgan, Professor Curtis Dobson and Dr Bianca Price 

        Contact lenses and their care have evolved greatly over the last few decades. However, wearers can still be troubled by symptoms of ocular irritation, a major reason for people dropping out of lens wear. Tear film constituents are known to deposit on and within the contact lens material contributing to these concerns. Clinical researchers, lens designers and lens manufacturers are trying to find new ways to address this. Researchers at the University of Manchester have been looking at tear film proteins and how they might be exploited to prevent contact lens infection and inflammation. Professor Philip Morgan, Professor Curtis Dobson and Dr Bianca Price discuss their recent research.

        Unit 2 - Eye tracking technology (~16 mins)

        David Thomson and Polly Dulley 

        In the last two decades, there have been great advances in vision testing and screening software. With cutting edge technology becoming more accessible, new techniques are being developed to examine ocular movements. A new clinical eye tracker provides a powerful tool for diagnosing and managing a wide range of conditions including binocular vision anomalies, various neurological conditions and reading difficulties. The device uses infra-red cameras to detect eye position to an accuracy of as little as one degree and records exactly where the patient is looking. David Thomson, former Professor of Optometry at City University, speaks to Polly Dulley about this latest innovation in eye assessment.
