    摘要: A low or high refractive index corneal inlay optical lens adapted to be inserted singly or multiply between the layers of a cornea to correct refractive errors in eyesight, wherein the implanted lens is a solid transparent uncoated lens having no apertures therethrough, of a diameter less than that of the optic zone of the eye under normal light or bright light conditions, such that the movement of fluids, nutrients and gases throughout the corneal layers is unimpeded, and wherein the composition of the lens or lenses relative to that of the surrounding stromal tissue are such that multiple refractive indices may be created and multiple focal corrections are possible.

    摘要: A biocompatible corneal inlay ring apparatus for altering the curvature of the central optic zone of the cornea of the eye without intrusion into this optic zone, comprising a continuous ring of a fixed diameter greater than that of the optic zone, of a thickness and geometry such that the curvature of the central optic zone is flattened to an extent appropriate to the refractive correction desired, and of a composition having a refractive index within about 2.0% of that of the corneal tissue.

    摘要: Bicomposite intraocular lenses and methods for their manufacture are disclosed. Bicomposite, hydrogel intraocular lenses with one or more haptic portions having a lower water content than the corresponding optic portions, and methods for their manufacture are disclosed. The bicomposite lenses are manufactured by (i) preparing a bicomposite button of hydrogel material containing one or more polymers or copolymers; (ii) lathing the button to produce a dehydrated intraocular lens with an optic and at least one haptic; and (iii) hydrating the lens.

    摘要: A phaco-emulsification needle is provided for use with a plastic or elastomeric sleeve, the needle having a mid-region portion defining a plurality of outwardly extending projections forming longitudinally-oriented grooves that provide adequate irrigant flow rates to the anterior chamber of the eye, even when the entry wound compresses the sleeve against the outer surface of the needle, thereby reducing the risk of collapse of the anterior chamber due to inadequate irrigant flow and reducing the risk of excessive heat transmission to the entry wound.
