<p>An instrument for the insertion of an intraocular lens into an eye comprises a body portion, e.g. a barrel, a nose portion having a lumen through which the lens passes, and a push rod connected to a plunger. Within the nose portion is an insert (30) which defines a passageway (40) therthrough. The passageway has a configuration which includes a smoothly continuous undulating surface (42, 44) upon which a lens rests. A cutout (52) accommodates the trailing haptic. For acrylic lenses, the undulating surface is preferably provided by a recess in the bottom of the passageway, the recess reducing in width and depth to define an upwardly sloping surface on which the lens is deposited.</p> |
