Claim Text:
1. An actuator for a device for delivery of ophthalmic lenses, the actuator comprising: a barrel, a plunger receivable within the barrel and movable in an axial direction between a first, withdrawn position and a second, more advanced position, a coupling operable between the plunger and the barrel and operable selectively in a first condition and a second condition, wherein in the first condition the coupling is configured to allow the plunger to move in the axial direction relative to the barrel from the first position to the second position when an axial load is applied to the plunger in the axial direction, and wherein in the second condition the coupling is configured to allow the plunger to move in the axial direction relative to the barrel from the first position to the second position when the plunger is rotated relative to the barrel, and a resilient biasing member which biases the coupling into its second condition, the coupling being responsive to the axial load on the plunger opposing the bias of the resilient biasing member to change from the second to the first condition and from the first to the second condition on release of the axial load.
