1. A device for implanting an intraocular lens comprising:
a piston rod
a pressurized gas device configured to impart pressurized gas pressure to the piston rod to move the piston rod from a retracted position to an extended position;
a compression chamber comprising a dampening medium, the dampening medium comprising a substantially incompressible fluid, and the dampening medium applying dampening pressure to the piston rod that counteracts the pressurized gas pressure;
a channel configured to drain the dampening medium from the compression chamber;
a valve configured to close or open the channel; and
an intraocular lens retaining portion comprising an intraocular lens for insertion into an eye of an animal and aligned with the piston rod such that the piston rod pushes the intraocular lens from the intraocular lens retaining portion when the piston rod moves from the retracted position toward the extended position.
