摘要：
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 a spring 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.
