A lens mold carrier () comprises: a frame () extending in a plane (x,y; u,v) and comprising a plurality of individual compartments (); at least one mold unit () arranged in one of the individual compartments () in a manner secured against falling out, the at least one mold unit () including an adapter piece () and a lens mold () fixedly connected to the adapter piece (). The adapter piece () is floatingly arranged within the compartment () to allow for limited movement of the adapter piece () within the compartment () at least in a translation plane parallel to or coincident with the plane (x,y; u,v) in which the frame () extends.

There are described a method for applying a coating to a surface of an ophthalmic lens mold. The mold includes male and female () mold halves, with each of the mold halves being provided with a lens forming surface (). The method includes

Method for molding an ophthalmic lens

The present invention relates to a mold half for making an ophthalmic lens, in particular a contact lens, wherein the mold half comprises a release sheet removably arranged on the mold surface of said mold half to separate a lens forming material from the mold surface, as well as to a method for applying a removable mold release sheet to said mold half. The mold half of the invention comprises a vacuum means to removably attach said release sheet to said mold surface, and preferably the mold half further comprises a pinch-off rim for forming the edge of said ophthalmic lens.

Mold release sheet

A gripper for grasping an ophthalmic lens immersed in a liquid, for example a contact lens or soft contact lens, the gripper including a housing having an opening arranged at the distal end of the housing, the opening being in communication with an interior space defined by the housing and being sized to allow the ophthalmic lens to pass therethrough; a supply channel to generate suction in the interior space of the housing to allow the ophthalmic lens together with an amount of the liquid in which the ophthalmic lens is immersed to be sucked through the opening into the interior space of the housing; and a supply channel for generating overpressure in the interior space of the housing so as to allow the ophthalmic lens together with the amount of liquid to be released from the interior space through the opening at the distal end of the housing.
