The extraction of the rabbit lens is described using a 25 G irrigating needle and a 22 G aspirating needle; at the latter's bevelled tip lens fragmentation occurs due to the longitudinal ultrasonic vibrations generated there--an 'acoustic horn' causes the tip to vibrate with large amplitudes. The use of small needles allows considerable manoeuvrability in the anterior chamber and usually eliminates the need for corneal suturing. Push-pull coupled syringes equate the volume of irrigation with that of aspiration. This procedure makes possible lens extraction through an aperture in the anterior capsule of the rabbit's lens and a similar machine is being constructed for trial on human cataract.
描述了使用25G冲洗针和22G抽吸针对兔晶状体进行摘除的方法；在后者的斜面尖端，由于在那里产生的纵向超声振动，晶状体发生破碎——一个“声学喇叭”使尖端大幅度振动。使用小针在前房内具有相当大的可操作性，通常无需缝合角膜。推挽式耦合注射器使冲洗量与抽吸量相等。该操作使得通过兔晶状体前囊膜上的一个小孔进行晶状体摘除成为可能，并且正在制造一台类似的机器用于人类白内障试验。
