Power Mapper
Currently available commercial instruments for the spatially resolved power measurement of ophthalmic lenses have insufficient power accuracy and spatial resolution to assess the quality of the latest generation of advanced contact lens designs. A new instrument has been developed and is currently being validated to ensure that manufactured lenses comply with design specifications. An international patent application has been filed for the Power Mapper.
Model Eye
An optical ray tracing model as well as physical bench top model eye is being developed in the Technology laboratory by one of the international PhD students. The model will be a useful tool to simulate and explain the optical performance of various types of vision correction devices, from IOLs to spectacle lenses. An international patent application has been filed for the Model Eye.
Optical Modelling and Lens Design
Significant advances had been made in recent years in numerical modelling techniques to predict and optimise the performance of vision correction devices, and this continues in a number of projects. The Anti-Myopia, Dynamic Vision and Corneal Onlay projects all benefit from the optical ray-tracing and design results, shortening product development time and providing better visual outcomes. Integrating the ray-tracing modelling with custom developed lens design software provides the link from research to manufacturing and commercial product.
Finite element modelling is also helping to design new vision correction lenses. For example a PhD project involves the development of software for creating and analysing finite element models to help design soft orthokeratology lenses which will ultimately be tested clinically.
