Abstract
A method of manufacturing an ophthalmic lens using a first mold portion and a puck assembly. The puck assembly comprises a carrier puck. The puck assembly supports at least one of the first mold portion and the lens during at least two of the following ophthalmic lens manufacturing steps: assembling the first mold portion and a second mold portion into a mold assembly including a lens-defining cavity containing a lens precursor material; curing the lens precursor material in the mold assembly to form a lens; separating the mold assembly such that the lens remains attached to the first mold portion; detaching the lens from the first mold portion; extracting unwanted material from the lens; hydrating the lens; inspecting the lens, and packaging the lens.
