  • Method and apparatus for measuring wavefront aberrations
    Patent number: 6880933
    Abstract: An apparatus and method for measuring wavefront aberrations. The apparatus comprises a reflecting device for reflecting selected portions of the wavefront, an imaging device for capturing information related to the selected portions, and a processor for calculating aberrations of the wavefront from the captured information.

  • Progressive cylinder ophthalmic lenses
    Patent number: 6802607
    Abstract: The invention provides methods for designing lenses useful for correcting astigmatism in which there is a progressive cylinder power. The lens of the invention permits the cylinder power to act under low luminance situations to a different extent than in higher luminance situations eliminating the need for extra toric minus power that may interefere near vision at mid range luminances while assisting distance vision at low luminance conditions.

  • Hybrid multifocal contact lenses
    Publication number: 20040141150
    Abstract: The invention provides a multifocal ophthalmic lens that is a hybrid lens in that it combines both soft lens material and rigid lens material. The lens is more comfortable to wear than a rigid lens and yet it provides correction for astigmatism without the need for the addition of cylinder power.
