摘要	A system for staking a haptic to an optic to form an intraocular lens using a laser beam operating near the infrared range with a coaxial aiming laser beam operating in the visible range. A portion of the haptic is inserted into the optic through a radial bore and is exposed through an axial bore spanning from the optic upper surface to the radial bore. The coaxial laser beams are collimated and then focused using a microscope objective through the axial bores, onto the exposed haptic. Aiming of the coaxial beams onto the optic and haptic is aided by the use of a magnifying CCD camera positioned with its optical axis at a 45 DEG angle to the optic horizontal plane. The coaxial lasers, which are typically focused to a minor diameter which is greater than or equal to the inner diameter of the axial bore, make contact with the exposed haptic. Consequently, the haptic is melted and is then allowed to cool, coalescing into a bead staking the haptic to the optic.
其他摘要	一种用于使用在红外范围附近操作的激光束将触觉器固定到光学器件以形成人工晶状体的系统，其中同轴瞄准激光束在可见光范围内操作。触觉部分通过径向孔插入光学元件中，并通过从光学元件上表面跨越到径向孔的轴向孔暴露。同轴激光束被准直，然后使用显微镜物镜通过轴向孔聚焦到暴露的触觉部分上。通过使用放大CCD摄像机来辅助同轴光束到光学器件和触觉部分上，该摄像机的光轴与光学水平面成45°角。通常聚焦到小于或等于轴向孔内径的小直径的同轴激光器与暴露的触觉部件接触。因此，触觉部分被熔化，然后被冷却，聚结成珠子，将触觉部分固定到光学部件上。
