Embodiment Construction

[0027] The following detailed description, taken in conjunction with the accompanying drawings, is intended to describe various embodiments of the invention and is not intended to represent only embodiments in which the invention may be practiced. The detailed description includes specific details for a thorough understanding of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0028] The capsular capture snare (10) may find application primarily in the field of cataract surgery, and more specifically, manipulation of intraocular lenses. Typically, during cataract surgery, the patient's clouded lens is removed to allow light to pass through to the retina. After the cataract has been removed, the lens is replaced by an intraocular lens assembly injected into the space defined within the lens capsule. The surgeon must then properly position the lens. Such procedures require prec...

Abstract

A surgical tool for manipulating a haptic of an intraocular lens. The surgical tool includes an elongated center rail having a traveler slideably disposed within the center rail, the center rail being at least partially disposed in a first housing, an actuator operatively connected to the traveler and fixedly connected to the center rail, a conduit partially disposed within the first housing and slideably coupled to the traveler, and an engaging member selectively extendable out of the conduit, wherein actuation of the actuator manipulates the engaging member.

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 253,636, filed October 21, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a surgical tool for implanting an intraocular lens in a human eye. In particular, the invention relates to a surgical tool capable of holding and positioning at least the haptic of an intraocular lens. Background technique [0004] The field of refractive surgery has grown rapidly over the past few decades. However, current surgical instruments used in refractive surgery are not customized for a particular procedure. In particular, the most commonly performed refractive surgical procedures, such as, for example, cataract extraction with intraocular lens implantation, do not have tools or equipment specifically configured to actually effectively facilitate the procedure. In particular, when imp...
