Patent number: 10889036Abstract: 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.Type: GrantFiled: February 7, 2018Date of Patent: January 12, 2021Assignee: INNOVALENS B.V.Inventors: Emerentius Marie Josephus Antonius Van Dijk, Joery Johannes Sinkeldam
