This device for stretching the haptics of an intraocular lens has at least two haptic guiding surfaces, a seat arranged with respect to the guiding surfaces so as to allow contact between a first point on each haptic and its corresponding guiding surface, and a lens guiding arrangement operable to allow the lens positioned in the seat to be moved along a path in the optic axis direction to bring at least a second point on each haptic into contact with, or closer to, its corresponding guiding surface and to orient each haptic in a less curved state, wherein the guiding surfaces extend in opposite directions from a channel operable to receive the lens.
A device for stretching the haptics of a deformable intraocular lens, the lens in un-deformed state comprising a) a roughly disc shaped optic part, defining an optic plane and a concentric optic axis normal to the plane, configured to act as a lens when inserted into an eye, and b) at least two elongated haptic legs, each leg having an inner end attached to the optic part, an outer end being free and intermediate points in between the inner end and the free end, each leg being curved in an unstressed state, the curvature defining a curve plane for each leg, and being flexible to at least a less curved configuration under stress, the device comprising i) at least two haptic guiding surfaces respectively arranged for at least two haptic legs, ii) a seat arranged with respect to the guiding surfaces so as to allow, when the lens is positioned in the seat, contact between a first point on each leg and its corresponding guiding surface, and iii) a lens guiding arrangement operable to allow the lens positioned in the seat to be moved along a path in the optic axis direction to bring at least a second point on each leg into contact with, or closer to, its corresponding guiding surface, to orient each leg to a less curved state, wherein the guiding surfaces extend in opposite directions from a channel operable to receive the optic part, and
