  • Patent number: 10889036
    Abstract: A cast mould for manufacturing a contact lens or an intraocular lens, wherein the cast mould 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 mould is provided for manufacturing such a cast mould and a method for manufacturing such a cast mould. The injection mould is provided with a mould cavity with a plunger biased by spring means towards the mould cavity which serves for compensating shrinkage which occurs during the curing of the plastic injected into the injection mould. Also described is a method for manufacturing a contact lens or intraocular lens with the aid of the cast mould, as well as a contact lens or intraocular lens obtained with this method.

  • Patent number: 9566749
    Abstract: A system for manufacturing ophthalmic devices, in particular contact lenses or intraocular lenses, includes at least one injection molding machine for manufacturing a cup bottom part and cup top part to form a cast mold, a cooling station, an injection assembly arranged for injecting an amount of monomeric material into the cup bottom part, a curing assembly, a first optical inspection assembly for determining at least one first optical cup part parameter, a second optical inspection assembly for determining at least one optical combination parameter of the combination of the cured monomeric material formed into a lens and the cup part that bears the lens, and an electronic control provided with a calculation module for determining at least one optical lens parameter of the lens on the basis of the cup part parameter and the combination parameter. Possibly, production parameters can be adjusted on the basis of trend changes of the lens parameters of produced lenses.
