    摘要: Eine Silikon-Kontaktlinse weist einen radialen Querschnitt der Innenfläche der Kontaktlinse auf, dessen Randbereichs-Kontur zwischen einem Wendepunkt und der Außenkante konvex ist. Zu ihrer Herstellung wird ein Silikon-Vorläufermaterial zwischen eine weibliche und eine männliche Form eingebracht und polymerisiert, und die polymerisierte Kontaktlinse wird mittels einer diese quellenden Flüssigkeit aus der Form ausgelöst und ohne Randbearbeitung fertiggestellt.

    摘要: There are described a method for applying a coating to a surface of an ophthalmic lens mold. The mold comprises male and female (20) mold halves, with each of the mold halves being provided with a lens forming surface (21). The method includes - applying a temporary coating to at least a portion of at least one of the male and female mold halves (20), the temporary coating being capable of reducing adhesive forces between a lens forming material and the lens forming surface (21); and - drying the temporary coating applied to the portion of the lens forming surface (21). Also described is a device (1) for applying such temporary coating to the portion of the lens forming surface (21) of the ophthalmic lens mold.

    摘要: A method of making a contact lens involves adding a lens-forming mixture to a contact lens mold, copolymerizing the lens-forming monomers to form a contact lens, releasing the contact lens from the mold; and removing the polymeric material from the contact lens. The polymeric material is not reactive with the lens-forming monomers, but is included in the lens-forming monomer mixture to facilitate releasing the contact lens from the mold.

    摘要: The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a non-crosslinkable hydrophilic polymer into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the non-crosslinkable hydrophilic polymer and to provide a disparity of about 10 N or less in mold separation force. The non-crosslinkable hydrophilic polymer has a limited miscibility with the lens-forming material low enough to successfully and timely form an intact interfacial film with a sufficient thickness at an interface between the mold and the fluid composition therein, and has a structure that minimizes entanglement of the non-crosslinkable hydrophilic polymer in the interfacial film with the polymer matrix of the formed lens.

    摘要: The present invention discloses improved methods and systems for inspecting an ophthalmic lens by exposing the ophthalmic lens to a processing aid solution that includes RCO 2 CH 2 CH 2 0(CH 2 CH 2 O) x CH 2 CH 2 O 2 CR where R comprises (equals) at least one of : CF 3 CF 2 (CF2) x CH 2 ; CH 3 CH 2 (CH2) x CH 2 ; and Ry[Si(CH 3 )2o] x (CH2) 3 , while the lens is contained in a ophthalmic lens receptacle, in order to facilitate the removal of bubbles and center the lens in the ophthalmic lens receptacle with a reduced incidence of ophthalmic lenses being folded over on themselves. The decreased incidence of bubbles and proper positioning of the ophthalmic lens in turn facilitates accurate inspection.
