摘要： An injector (900) for inserting an intraocular lens (930, 980) into an eye includes a lumen (910). The lumen (910, 960) can include a terminal portion (912, 962) at a distal end (916, 966) and a proximal portion (914, 964) juxtaposed with the terminal portion (912, 962). An injector plunger (920, 970) can be disposed within the lumen (910, 960) for generating a driving force (944, 994) on the intraocular lens (930, 980). The injector (900) can include a lens frictional force (942) that has a first value when the lens (930, 980) is at a first location (Ll) within the proximal portion (914, 964) and a second value when the lens (930, 980) is a,t a second location (L2) within the terminal portion (912, 962). The first value can be smaller than the second value.

摘要： A method of preparing an accommodating intraocular lens having an optical axis for subsequent implantation involves providing an intraocular lens having first and second viewing elements interconnected by plural members. At least a portion of the members are disposed from the optical axis by a distance greater than a periphery of at least one of the viewing elements. The distance is measured orthogonal to the optical axis. The method further involves drawing the members inwardly toward the optical axis by relatively rotating the first and second viewing elements, and increasing the separation between the viewing elements along the optical axis while drawing the members inwardly.

摘要： An accommodating intraocular lens includes an anterior portion having an anterior viewing element and a posterior portion having a posterior viewing element, the viewing elements positioned for relative movement along an optical axis in response to ciliary muscle action. The anterior and posterior portions meet at first and second apices of the lens located on a transverse axis of the lens, and at least one of these portions has a separation member with a contact surface for preventing contact between the viewing elements. The contact surface contacts an opposing surface of the intraocular lens over a contact area when the portions are at the minimum separation distance. The entirety of the separation member is located outside a projection of a periphery of the refractive zone out of contact with one of the anterior posterior portions when the viewing elements are separated by a distance greater than the minimum separation distance.

摘要： C:\NRPonbl\DCC\AXL\2751947. .DOC-33/2n)I10 Disclosed is an apparatus for compacting an intraocular lens. The apparatus comprises a lens compactor having a first configuration for retaining the intraocular lens in an 5 unstressed condition and a second configuration in which the compactor stresses the lens into an at least partially compacted condition without advancing the lens along an injection axis of the compactor. The compactor accomplishes this by applying a compacting force in a direction generally orthogonal to the optical axis of the lens. The compactor is responsive to a compactor actuator that is movable by a user to change the compactor from the first 10 configuration to the second configuration. Additional apparatus and methods are disclosed as well. PT/CAL Ar/ lATERAL AX/S TRANSVERSE AX/S FL. ft. (t'o~fOR 4tf
