Benefits of technology

The hybrid lens provides superior optics, comfort, and stability, enabling correction of higher-order aberrations and presbyopia, maintaining corneal health, and reducing dryness, while being resistant to protein deposition and foreign body migration, thus offering 'super vision' beyond conventional contact lenses.

Problems solved by technology

However, this is not the case with contact lenses.
Popular soft contact lenses cannot achieve the same result as spectacles or laser refractive surgery because of dimensional variations in fabrication.
Hard contact lenses, which may provide the platform to achieve the results of spectacles, are not as comfortable as soft contacts and lack the necessary positional stability on the eye.

Abstract

A hybrid hard-soft contact lens is provided. Several embodiments of the invention include methods of coupling the hard and soft sections of the contact lens. Other embodiments of the invention include contact lens materials and coatings that increase oxygen transmission though the lens. Yet other embodiments of the invention are directed to cost-effective manufacturing methods of a hybrid hard-soft contact lens. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Description

[0001] Priority is claimed to U.S. Provisional Application Ser. No. 60 / 408,618, filed Sep. 6, 2002, titled “Hybrid Contact Lens System and Method,” which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention generally relates to contact lenses. More particularly, the invention concerns a hybrid hard-soft contact lens. BACKGROUND OF THE INVENTION [0003] Vision correction is on the verge of a revolution. New technologies to measure the aberrations or distortions in the optics 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 precisely measure the eye's aberrations so that vision may be corrected up to 20 / 10. Wavefront sensing is the method for rapidly, and very accurately, assessing the aberrations in an individual's eye to create a customized prescription for correction. [0004] However, once the eye's aberrations have been m...
