The Corneal Onlay represents a new generation of vision correction, capable of delivering permanent, high quality vision to the billions of people experiencing some of the most common eye conditions (refractive errors). It stands apart from existing refractive correction products because of its ability to deliver the convenience of permanent, high quality vision while also being reversible.

Until recently, conventional lens testing machines used to evaluate lens material have proven to be unsuitable because of the softness of the gels and the unique environmental conditions required to measure the physical properties.

As part of the Dynamic Vision project the Technology group has developed a new tensile and compression testing machine to accurately measure the soft polymer gel properties. The optical transmission characteristics of the same materials were determined in our optical laboratory by using an experimental set-up on the lab bench.

The Technology group has made a significant contribution to the Anti-Myopia project, including hardware and software for measurement of peripheral vision.

Some of the key design features for the optical intervention devices were developed by the optical experts within the technology team. Specialised metrology equipment was developed to verify the accurate manufacture of these devices.
