An insertion system for an intraocular lens includes an intraocular lens
having a deformable optical portion, a lens package for storing the lens
in a state in which no stress acts on the optical portion of the lens, a
deforming member for deforming the lens to a reduced size, and an
insertion device. The insertion device has an insertion tube through
which the deformed lens is inserted into an eye, and a pusher mechanism
for pushing and inserting the lens into the eye. The lens package has a
function for attachment to the insertion device and a function for acting
as a portion of the mechanism to be provided by the insertion device.
