1. An intraocular lens insertion and filling system comprising:
- a fluidic system including one or more pumps and one or more reservoirs for a liquid;
a conduit, fluidically connected to the pump and having a distal end configured for insertion into an intraocular lens;
an insertion mechanism including a handpiece terminating in an insertion tube, wherein;
the handpiece surrounds a distal portion of the conduit;
the insertion tube is configured to receive the lens in an at least partially deflated state; and
the handpiece includes an advancement mechanism for causing relative movement between the insertion tube and the lens received therewithin, whereby activation of the advancement mechanism causes the lens to be ejected from a distal end of the insertion tube.

Abstract
Peripheral surgical systems are used for insertion and filling of fluid-filled intraocular lenses, reaccessing and modifying fluid-filled intraocular lenses, and explantation of lenses. Although one peripheral surgical unit may perform all of these functions, in some embodiments different units perform different functions—i.e., each function may be performed by a separate unit, or the functions may be distributed over a smaller number of functional units.

10. An intraocular lens insertion and filling system comprising:
-
a fluidic system including at least one pump and at least one reservoir for a liquid, gas, or solute; and first and second conduits fluidically connected to the pump and having distal ends configured for (i) contact with an intraocular lens and (ii) cooperation in retaining and filling the lens. - View Dependent Claims (11, 12, 13)

14. A method of filling an intraocular lens, the method comprising the steps of:
-
providing a conduit having a distal end disposed within and movable relative to an insertion tube; inserting the distal end of the conduit into the lens and positioning the lens within the insertion tube; partially inflating the lens with liquid via the conduit; causing ejection of the lens from the insertion tube; and further inflating the lens with the liquid to achieve a target volume. - View Dependent Claims (15, 16, 17, 18, 19)
