The technology, led by Dr Shirley Tang from the University of Waterloo, aims to create truly personalised lenses with patient-specific surfaces for a precise fit and vision correction. A new silicone formulation was developed as conventional silicone is incompatible with 3D printing, alongside an ultra-thin coating process to smooth imperfections and maintain optical clarity. These innovative lenses have undergone successful lab testing, with researchers now preparing for trials in actual eyes. The project has secured a provisional patent for its hydrophilic silicone material and received a Gold Medal at the Shanghai International Exhibition of Inventions in June 2026.
