A lens injector includes a thin sheet-like lens glide member, mounted upon
a tapered knife, that maintains a wedge-shaped opening in the cornea upon
withdrawal of the knife. The lens is thereafter advanced under the cornea
by a plunger in the injector that maintains the lens in place as the
injector device is removed. A multiple point blade knife may
simultaneously make a set of several small, connected incisions. The fact
that each blade has only a limited depth means that the resulting wide
incision can be created without the need to penetrate deeply into the
cornea, as would be necessary with a single-point blade of the desired
width. This is especially beneficial for creating Z-shaped incisions,
which become self-sealing when internal pressure pushes the inner layer
against the outer layer. This shortens the process significantly, which
then results in less trauma to the eye and streamlines the entire
procedure.
