    • A mandrel (300) for holding an intraocular lens blank (200) during manufacturing includes an intraocular lens holding section configured to hold an intraocular lens, the intraocular lens holding section including: a central cavity (310) configured to hold a mounting material (315) such that the mounting material contacts an optic of the intraocular lens blank when the intraocular lens blank is mounted on the mandrel, and a projection (325) extending around a periphery of the central cavity, the projection having an outer wall (330) and an inner wall (335), and the projection being configured such that an outer peripheral edge of the intraocular lens blank extends up to or beyond the projection when the intraocular lens blank is mounted on the mandrel. A second mounting material (320) is deposited in the first trench (340) and then the haptic is milled using e.g. an end mill (365).
    • 用于在制造过程中保持眼内透镜毛坯(200)的心轴(300)包括:眼内透镜保持部,被配置为保持眼内透镜;眼内透镜保持部,包括:中心腔(310),其构造成保持安装材料 ),使得当眼内透镜毛坯安装在心轴上时,安装材料接触眼内透镜毛坯的光学元件,以及围绕中心腔的周边延伸的突起(325),突起具有外壁(330)和 内壁(335),并且所述突起被构造成使得当所述眼内透镜毛坯安装在所述心轴上时,所述眼内透镜毛坯的外周边缘延伸到所述突起的上方或外侧。 第二安装材料(320)沉积在第一沟槽(340)中,然后使用例如第二沟槽(340)铣削触觉件。 立铣刀(365)。
