A hybrid contact lens comprises a central zone comprising a substantially rigid, gas permeable material having a DK of at least 30, 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.

Hybrid contact lens system and method

A hybrid contact lens comprises a substantially rigid zone having a base curve and a substantially flexible hydrophilic portion coupled to the substantially rigid zone, wherein the substantially flexible portion has one of a plurality of radii.

Hybrid contact lens system and method of fitting

A hybrid contact lens comprises a substantially rigid zone having a base curve with a first curved section defined by an apical radius and an aspheric section defined by a conic constant. A substantially flexible hydrophilic peripheral portion is coupled to the substantially rigid zone, the peripheral portion having one of a plurality of radii, wherein a conic constant of the aspheric section varies with apical radius, so as to provide a nearly constant deviation between the aspheric shape of the aspheric section and a sphere having a radius equal to the apical radius, regardless of the length of the apical radius.

A hybrid contact lens comprises a substantially rigid zone having an aspheric base curve with a given apical radius and a substantially flexible hydrophilic peripheral portion coupled to the substantially rigid zone, the peripheral portion having one of a plurality of radii, wherein a conic constant of the substantially rigid zone varies with apical radius, so as to provide a nearly constant deviation between the aspheric shape of the base curve and a sphere having a radius equal to the apical radius, regardless of the length of the apical radius.

Methods of manufacturing hybrid contact lenses using a mold are provided. The methods include pouring liquefied resin of a substantially rigid material within an inner section, curing the substantially rigid material, pouring liquefied resin of a substantially flexible material within an outer section and curing the substantially flexible material. In some embodiments, a wall disposed between the rigid and flexible materials is angled and/or bent to increase bonding strength between the rigid and flexible sections. The curing steps involve the application of heat, UV light, or a combination of both heat and UV light.

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.

A method of manufacturing a hybrid contact lens having a substantially rigid center portion and a substantially flexible outer portion, comprising forming the substantially rigid center portion, treating the substantially rigid center portion to form a coating on the perimeter of the substantially rigid portion, forming the substantially flexible outer portion around the substantially rigid center portion and chemically bonding the substantially flexible portion to the substantially rigid portion. Hybrid lenses comprising a substantially rigid center portion and a substantially flexible outer portion joined at junction comprising a first segment and a second segment are also provided.

A contact lens is provided. One embodiment of the present invention provides a method for fitting and prescribing a contact lens. Another embodiment of the present invention comprises a contact lens construction that provides a stable prescription platform. Yet another embodiment comprises a contact lens that is constructed to accommodate ectasia associated with keratoconus. 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.
