Abstract: A gripper system comprises:

a gripper shaft;
a vacuum source;
a first valve arranged between the vacuum source and the suction tube;
a liquid reservoir;
a source of pressurized gas;
a second valve arranged between the source of pressurized gas and the suction tube or the liquid reservoir;
a control unit for controlling the first valve and the second valve such that:
for picking the ophthalmic lens up, suction is supplied to the suction tube;
during transporting the ophthalmic lens, the suction tube is filled with liquid from the liquid supply tube;
for releasing the ophthalmic lens from the gripper head, liquid is pressed through the fluid channel and through the suction opening of the gripper head.
