摘要： A cast mold for manufacturing a contact lens or an intraocular lens, wherein the cast mold is provided with a central part and a bearing ring and a flexible connection between the central part and the bearing ring. Further, an injection mold is provided for manufacturing such a cast mold and a method for manufacturing such a cast mold. The injection mold is provided with a mold cavity with a plunger biased by a spring towards the mold cavity which serves for compensating shrinkage which occurs during the curing of the plastic injected into the injection mold. Also described is a method for manufacturing a contact lens or intraocular lens with the aid of the cast mold, as well as a contact lens or intraocular lens obtained with this method.

摘要： Method for manufacturing a cylindrical optical insert (64) for an injection mold (50) for manufacturing an ophthalmic device (12, 20, 250, 260). The method comprises manufacturing an optically accurately defined surface (66, 66') of the optical insert (64) on a lathe (200) with a CNC control, the lathe being provided with a rotatable clamping head (202) whose rotational position is controllable and in which the optical insert (64) is in a clamped position during the manufacture of the optical surface, whereby a stop surface or a pin recess (106) of the optical insert (64) is provided with a cutter or a drill (206) while the optical insert is in the clamped position in the clamping head, whereby the CNC control defines the position of the stop surface or the pin recess (106) with respect to the optically accurately defined surface (66) through accurate rotational control of the clamping head for positioning the optical insert with respect to the cutter or drill.

摘要： A method for manufacturing a semimanufacture intended for manufacturing therefrom an intraocular lens or a contact lens, wherein a cup bottom part and a cup top part are injection molded, at least one of the two cup parts being an optical cup part which is provided with an optically accurately defined surface, wherein monomer is injected into the cup bottom part, and the cup top part is placed on the cup bottom part so as to form a cast mold filled with monomeric material. Next, the monomer in the cast mold is cured to form a lens blank, and the cup top part and the cup bottom part are separated from each other for exposing the formed lens blank, which is bonded to the optical cup part during curing, to provide a semimanufacture assembly, to be worked with a lathe, which comprises the optical cup part and the lens blank. Then, the lens blank can undergo a turning operation to form a lens having two optically accurately defined surfaces.

摘要： An insert assembly for the purpose of an injection mold for manufacturing a first casting mold half of a casting mold for manufacture of an ophthalmic device, wherein the insert assembly is receivable in an injection mold half of the injection mold and wherein the insert assembly includes an insert assembly end surface which bounds an injection mold cavity of the injection mold for forming a first casting mold half. The insert end surface is provided with at least one notch which forms a bounding structure cavity for forming a bounding structure which is an integral part of the first casting mold half to be formed with the injection mold and which, after placement of a second casting mold half on the first casting mold half, bounds at least one haptics cavity which links up with a lens cavity, wherein the haptics cavity is so configured that in use of the casting mold, after curing of monomeric material deposited in the casting mold, an intraocular lens is formed which comprises a lens and integrally formed-on haptics.
