Abstract:
1. A method for use with an intraocular lens and an intraocular lens insertion device, the intraocular lens including an optical area with an optical axis, an edge region that surrounds the optical area, and first and second haptics that extend outwardly from the edge region, and the intraocular lens insertion device including a lens storage section, a tube section having an opening through which the intraocular lens exits the intraocular lens insertion device, a plunger that moves through the lens storage section to the tube section along a lens advancement axis that extends through the lens storage section and the tube section, and a lens deformation mechanism associated with the lens storage section, the method comprising the steps of: prior to movement of the lens deformation mechanism, maintaining the position of the intraocular lens within the lens storage section in an unstressed state and on the lens advancement axis such that the intraocular lens defines front and back portions that are spaced from one another along the lens advancement axis and side portions that are spaced from one another in a direction transverse to the lens advancement axis; and folding the intraocular lens with the deformation mechanism into a U-shape where the front and back portions are spaced from one another along the lens advancement axis.
