Abstract: An ophthalmic lens mold includes a first mold half having a front side and a back side. The front side defines an optical surface. A second mold half has a front side defining an optical surface. Upon alignment of the first mold half with respect to the second mold half so that the front sides oppose each other, a mold cavity is formed between the front sides to form an ophthalmic lens therein from a moldable material. The first mold half includes a first section that transmits curing light and that extends from the back side to the front side. The first section includes at an area of the first mold half optical surface enclosed by an outermost circumference of the ophthalmic lens. A second section is co-molded with the first section and blocks the light.

Abstract: A method of making a colored contact lens comprises printing at least one layer of a colorant onto a contact lens using a printing process selected from the group consisting of ink jet printing, electrophotographic printing, thermal transfer printing, and photographic development printing. Printing can be done directly on the contact lens, on a film in a mold where the contact lens is formed, or on a cliché pad. Multiple layers of colorants can be printed onto a contact lens.

Abstract: A method of forming a coating of polyionic materials in a layer-by-layer-like manner onto a polymeric material is provided. A polymeric material, such as a contact lens, can be dipped once into a solution of polyionic materials such that layers of polyionic material can be formed thereon. A single dip solution of the present invention typically contains a polyanionic material and a polycationic material in a non-stoichiometric amount and maintained within a certain pH range.

Abstract: The present invention discloses a method for cleaning contact lens molds. The method comprises the steps of placing a contact lens mold within an enclosed or substantially enclosed area, directing an inflow of gas under pressure into the enclosed area against the contact lens mold, and providing an outflow of gas from the enclosed area, thereby dislodging and removing debris.

Abstract: A contact lens has top, a bottom, a rotational axis, an inner surface and an opposite outer surface having a plurality of zones. The plurality of zones include an optical zone, a ridge zone and a transition zone. The optical zone has a lower edge and includes a distance vision zone and a near vision zone. The distance vision zone has a first radius of curvature that provides distance vision correction. The distance vision zone also has a first area that is sufficient to overlay a substantial portion of a pupil of a user and is disposed in a first position within the optical zone so that the user's pupil is substantially subtended by the distance vision zone when the user is gazing at a substantially horizontal point. The near vision zone is substantially concentric with the rotational axis and extends radially outward from the distance vision zone.

Abstract: The invention enables more objective defect evaluation of ophthalmic lenses, especially contact lenses, to take place through the combination of the schlieren method with the transmitted light method, with the result that the advantages of these two different systems are combined. The schlieren method is in a position to illustrate the edge of a contact lens and its ruptures, in high contrast, for the CCD camera. Likewise, tears and surface defects can be made visible. Using the transmitted light method, the bubbles may be suitably prepared for the camera.

Abstract: A method of configuring and ordering a customized contact lens for a user. The method includes the steps of displaying a template eye image to assist the user in visualizing selected options for a customized contact lens, and displaying a plurality of contact lens selection options to the user. The information includes a plurality of selectable lens colors and lens design patterns. The method also includes the steps of sending an ordering request to order a contact lens incorporating lens colors and lens design patterns selected by the user, receiving the ordering request, and manufacturing a contact lens incorporating the lens colors and lens design patterns selected by the user.

Abstract: An irradiation device for treating molds comprising a UV irradiation source, and a means for holding the molds. The invention is also a method of treating molds, comprising the steps of exposing a mold to a high intensity UV radiation for a predetermined time.

Abstract: The invention relates to a process for coating a material surface comprising the steps of: (a) applying to the material surface one or more different comb-type polymers comprising a polymer backbone and side chains pendently attached thereto, wherein at least a part of the side chains carry a triggerable precursor for carbene or nitrene formation; and (b) fixing the polymer(s) onto the material surface using heat or radiation, in particular radiation such as UV or visible light. The polymers of the invention are useful for the modification of material surfaces and are particularly suitable for providing biomedical articles such as contact lenses with a hydrophilic coating.

Abstract: The invention relates to novel reactive polymers of formula wherein the variables are as defined in the claims. The polymers of the invention are useful for the modification of material surfaces and are particularly suitable for providing biomedical articles such as contact lenses with a hydrophilic coating.

Abstract: A contact lens includes a central zone and a peripheral zone. The central zone extends radially from a center to a central intermediate edge and has a radius corresponding to a radius of a contracted pupil of a user when subjected to a high ambient light condition. The central zone also has a constant first refractive power across the central zone. The peripheral zone extends radially from the central intermediate edge to an outer edge and has a radius corresponding to a dilated pupil of the user. The peripheral zone has a refractive power that is equal to the first refractive power at the intermediate edge and that increases radially to a second refractive power, different from the first refractive power, at the outer edge. The contact lens also includes a non-optical zone that extends radially from the outer edge to an outermost radius corresponding to a radius of a user's cornea.

Abstract: The invention is concerned with the problem of ensuring optimum drying of contact lenses on a gripper, while at the same time minimizing interruptions in operations. This is achieved by a convex shape of the end face of the blast nozzle.

Abstract: The present invention describes novel statistical copolymers and the preparation and possible uses thereof. Copolymers are described that are water-soluble and cross-linkable and that comprise the copolymerization product of a monomer mixture consisting substantially of a vinyl lactam (a) and at least one further vinyl monomer (b) of a different type selected from the group consisting of hydrophobic, hydrophilic and functional vinyl monomers, wherein the monomers are present in the copolymer in the form of statistically distributed building blocks, and, if a functional vinyl monomer is present as a building block in the copolymer, that building block is, where appropriate, modified with a reactive vinyl monomer (c), the reactive vinyl monomer (c) being linked to a building block of a functional vinyl monomer with retention of its vinylic group and with the formation of a covalent bond.

Abstract: The invention provides a method for treating or preventing ocular neovascularization. The method administers an effective amount of a staurosporine derivative to treat or prevent retinal or choroidal neovascularization. In each case, the effect on the pathologic blood vessels is dramatic and profound with complete or near-complete inhibition, but there is no identifiable toxic effect on mature retinal vessels.
