A method for charging a deformable intraocular lens into a receptacle through a slit or opening in the receptacle periphery, the lens in un-deformed state includes a roughly disc shaped optic part configured to act as a lens when inserted into an eye and 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 unstressed state and being flexible to at least a less curved configuration under stress. Steps include stretching the legs to align the legs along a substantially straight line, aligning or maintaining the substantially straight line over and substantially parallel with the slit or opening of the receptacle, and transferring at least the two legs through the slit or opening into the receptacle.
