A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.

Foldable intraocular lens and method of making

Apparatus and methodology for inserting an intraocular lens (IOL) into an eye. The apparatus includes a cartridge for holding an IOL and a handpiece with a body member for receiving the cartridge, an injector rod that is receivable by the body member, and a drive mechanism that longitudinally oscillates the injector rod in the body member when a rotational force is applied about a longitudinal axis in a single direction. In other words, a constant rotation in a single direction of the drive mechanism causes the injector rod to move distally and proximally in discrete increments, with the distal increments being larger than the proximal increments. Accordingly, the injector rod urges an IOL out of the handpiece in a two-steps-forward, one-step-back manner, thereby minimizing or eliminating the chance of the injector rod engaging with the IOL.

Methods and apparatus for inserting an intraocular lens into an eye

A guide shoe attachment for a clearing saw having a shaft defining a centerline, a transmission connected to the shaft including a hub rotatable in a predetermined blade rotation direction about an axis of rotation angled with respect to the centerline, and a circular blade connected to the hub. The guide shoe attachment has an elongate guide member extending radially outward from the hub generally in the direction of the centerline, parallel to and above the blade, providing a guide edge for guiding the saw. It includes a top plate forming a semicircular guard around for blade with fittings for connecting the attachment to the transmission at a position above the blade and forwardly of the transmission. The guide member includes a skid aligned with the guide edge. The guide edge is offset from a centerline of the clearing saw in the direction of blade rotation so that a tree contacting the guide edge is sawn within a kickback zone at the front of the clearing saw.
