<p>A method of generating data for use in fabricating a contact lens for an eye is provided. Posterior lens data defining a posterior lens surface for the lens is generated dependent on ocular surface data generated by a scanner to represent the ocular surface of an eye. Anterior lens data defining an anterior surface for the lens to define optical properties for the lens is then generated. The anterior lens data is generated dependent on the posterior surface data. The posterior lens data is generated dependent on scanned data representing the ocular surface of an eye. Also provided is a contact lens with support surfaces which contact the eye in use and supported surfaces formed in relief in the posterior lens surface and which are supported by the support surfaces to minimise or avoid contact between the lens and features on the ocular surface.</p> |
