Zusammenfassung:	Apparatus and method for cutting an IOL optic from an IOL blank whereby the resultant IOL optic has a square edge and the cutting is performed in a combined linear and rotational cutting movement. In another aspect, an IOL optic is provided which includes a square edge and helically shaped striations formed therein to help reduce glare. L'invention concerne un appareil et un procédé permettant de couper un élément optique IOL à partir d'une ébauche IOL, l'élément optique IOL ainsi obtenu présente un bord droit et le découpage est effectué dans un mouvement de découpe linéaire et rotatif combiné. Selon une autre variante, un élément optique IOL comprend un bord droit et des stries hélicoïdales pratiquées à l'intérieur de manière à réduire l'éblouissement.
