Abstract

A mold assembly for making an ocular device such as a contact lens, an intraocular lens or a lens blank has three pieces which include a sleeve, a first mold segment and a second mold segment. The first mold segment includes a peripheral skirt which extends away from a mold cavity and which terminates in an end portion which is in interference fit engagement with the sleeve for establishing a leak-resistant fluid seal.
