Abstract

A hybrid contact lens comprises a central zone comprising a substantially rigid, gas permeable material having a DK of at least 30 (x10<-11>), a relatively soft peripheral zone and an intermediate zone comprising a film or coating that is created around the central zone, and then cured. The film facilitates chemical bonding between the central zone and the peripheral zone, and also provides a protective barrier to prevent modification of the physical characteristics of the central zone. The film may be created by soaking the central zone in a chemical solution for a predetermined amount of soaking time. Methods of manufacturing such a hybrid contact lens are also provided.

Description

technical field [0001] The present invention relates generally to contact lenses and, more particularly, to hard-soft contact lenses. Background technique [0002] Vision correction is on the verge of a revolution. New techniques for measuring optical aberration and distortion of the eye will soon be available to the public. These new wavefront measurement techniques, such as Shack-Hartmann wavefront sensing or Talbot interferometry, can accurately measure the aberrations of the eye so that vision can be corrected up to 20 / 10. Wavefront sensing is a method of quickly and very accurately assessing the aberrations of an individual's eye, resulting in a specific ophthalmic prescription for correction. [0003] However, once the aberrations of the eye have been measured, whether using traditional methods or wavefront sensing, these measurements must then be translated into vision correction systems, such as eye surgery, eyeglasses or contact lenses. Recent advances in laser r...
