摘要： An intraocular lens folder having a generally planar, open frame in the shape of a rounded "A" with a rimmed, open head at the top of the "A." The base of the "A" forms a pair of opposing legs or handles that join to form a hinge at the crotch where the handles attach to the head. The hinge allows the handles to be squeezed together and yet spring apart when released. Squeezing the handles causes the top edge of the head rim to compress and move toward the hinge. The open head contains a plurality of projections terminating in open, relieved jaws into which the IOL is placed. The location of the projections is such that when the handles are squeezed together and the rim moves toward the hinge, two of the jaws moves toward each other, causing the IOL to be folded in half.

摘要： An infusion sleeve for an ultrasonic tissue removal surgical tool includes a sleeve designed to surround the ultrasonically driven tip of the surgical tool and create an irrigation fluid channel thereinbetween. The sleeve includes a flexible portion which permits retraction of the distal end thereof to permit contact between the tip of the surgical tool and body tissue to be destroyed or removed. The infusion sleeve also includes a rigid portion which is designed to prevent collapse of the sleeve around the ultrasonically driven surgical tip and prevent blockage of irrigating fluid flow and subsequent overheating of the tip and damage to adjacent body tissue.

摘要： An intraocular lens designed for ease of insertion and for minimizing contact with intraocular tissues comprises a lens body having an optical axis, two optical surfaces and a periphery to which is fixed at least one filamentous haptic extending circumferentially and radially from the point of attachment along a curvilinear path in space to a maximum distance from the optical axis. The haptic has a proximal segment adjacent to the attachment point, a medial segment attached to and continuous with the proximal segment and a distal segment attached to and continuous with the medial segment. At least a part of the distal segment lies at the maximum distance from said optical axis and constitutes the tissue-contacting portion of the haptic. The tissue-contacting element is tangent to a second plane parallel to the first plane and displaced from it along the optical axis, and at least the medial segment of the haptic traverses a path concave toward the first plane and avoiding intersection with the second plane.

摘要： An apparatus and method for implantation of intraocular lenses includes a resilient tubular sling which is positionable over parallel working ends of a crossover forceps. The sling allows an intraocular lens to be folded or curled up therein and held in that folded up position with the forceps tips in a closed position. The forceps presents a narror-in-cross-section moving crossover point behind the tips to allow the forceps tips to be inserted through a small incision in the eye, and then open to release the lens once within the eye. By maintaining the crossover point at the small incision, the forceps can release the lens even though it requires the opening of the forceps tips to a position wider than the incision in the eye. The resilient sling holds the folded lens compactly during movement through the small incision, and assists in urging a controlled release of the lens into the eye. The sling also avoids having to handle the lens with the forceps tips prevents damage to the lens.

摘要翻译： 用于植入人工晶状体的装置和方法包括弹性管状吊索，其可位于交叉镊子的平行工作端上。 吊索允许眼内透镜在其中折叠或卷曲并保持在折叠位置，镊子尖端处于关闭位置。 镊子在尖端后面呈现横截面移动的交叉点，以允许镊子尖端通过眼睛中的小切口插入，然后打开以在眼睛内释放镜片一次。 通过在小切口处保持交叉点，即使需要将镊子尖端打开到比眼睛中的切口更宽的位置，镊子也可以释放镜片。 弹性吊带在通过小切口移动期间紧凑地保持折叠的透镜，并且有助于将镜片控制释放到眼睛中。 吊带也避免了用镊子尖端处理镜片，防止损坏镜片。

摘要： A method and apparatus for operating on the human eye detects changes in load, more specifically, mechanical impedance, of the transducer and controls aspiration based on the load changes. A change from a lower load to a higher load indicates that harder tissue is being encountered and accordingly causes aspiration amount to increase. Conversely, a change from a higher load to a lower load indicates that aspiration amount should be quickly decreased since the tissue which is being encountered is softer. One way to detect the impedance is by a sensor, e.g., a piezoelectric element coupled to the operating needle detecting the movement thereof.

摘要翻译： 用于在人眼上操作的方法和装置检测换能器的负载变化，更具体地，机械阻抗，并根据负载变化控制抽吸。 从较低负载到较高负载的变化表明，正在遇到较硬的组织，因此导致吸入量增加。 相反，从较高负荷到较低负荷的变化表明，由于遇到的组织较软，所以吸入量应该快速降低。 检测阻抗的一种方式是传感器，例如耦合到检测其运动的操作针的压电元件。
