METHOD AND DEVICE FOR MANIPULATION OF AN INTRAOCULAR LENS

PROBLEM TO BE SOLVED: To provide a method for charging a deformable intraocular lens into a receptacle through a slit or opening in the receptacle periphery. SOLUTION: The method comprises the steps of (i) stretching the legs, simultaneously and sequentially, (ii) aligning or maintaining the substantially straight line over and substantially parallel with the slit or opening of the receptacle, and (iii) transferring at least the 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 having less curvature than the legs in unstressed state, (ii) a seat 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 guiding structure or a transfer opening and (iii) a lens guiding arrangement allowing passage of the lens with the haptics, having the less curvature, to a receptacle.
