A method for charging a deformable intraocular lens into a receptacle throug h a slit or opening in the receptacle periphery, the lens in un-deformed state comprising a) a roughly disc shaped optic part configured to act as a lens when inserted into an eye and b) at least two elongated haptic legs, each le g 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 bein g curved in unstressed state and being flexible to at least a less curved configuration under stress. The method comprises the steps of i) stretching the legs to align the legs along a substantially straight line, ii) aligning or maintaining the substantially straight line over and substantially parall el with the slit or opening of the receptacle, and iii) transferring at least t he two legs through the slit or opening into the receptacle. A device for stretching the haptics of a lens comprises i) at least two haptic guiding surfaces arranged for each of the at least two haptic legs, the guiding surfaces having less curvature than the legs in un-stressed state, ii) a sea t for the lens arranged with respect to the guiding surfaces so as to allow, when a lens is positioned in the seat, contact between a first point on the leg and its guidingstructure and iii) a lens guiding arrangement allowing th e lens to be moved along a path bringing at least a second point on the leg in to contact with, or closer to, its guiding structure or a transfer opening allowing passage of the lens with the haptics, having said less curvature, t o a receptacle.
