摘要： Apparatus for insertion of intraocular lenses into the eye are disclosed. In one embodiment, the apparatus comprises a loading chamber and an injection portion. The loading chamber has a proximal end and a distally extending opening. The loading chamber defines a first lumen and is adapted to receive an intraocular lens in an unfolded state at the distally extending opening and to fold the intraocular lens and maintain the intraocular lens folded as the intraocular lens is placed in the first lumen. The injection portion defines a second lumen aligned with the first lumen and is adapted to receive the folded intraocular lens from the first lumen in the second lumen. The injection portion has an open distal end through which the folded intraocular lens from the second lumen passes to be inserted into an eye.

摘要： A reusable cartridge assembly for a phaco machine includes a first plate with a plurality of flow channels therein and a sealing gasket with a sheet for sealing against the first plate to prevent fluid from leaving the flow channels. In addition, a tube is provided, fixed to the sealing gasket and protruding therefrom, for enabling engagement between the tube and a pump head for circulation of fluid through flow channels. A second plate is provided for applying a sealing pressure between the sheet and the first plate. In addition, the sealing gasket may include a sensing element for determining pressure within the flow channels.

摘要： A thin tip phaco needle is provided including a body having a longitudinal bore for enabling passage of debris from a surgical site, a threaded end for engaging an ultrasonic probe handpiece, and a tip, disposed at a distal end of the body, for cutting tissue. The tip includes a beveled, or stepped, edge having a wide proximal wall and a thin, distal, cutting wall of about half a width of the wide wall. The beveled edge functions to enhance cutting efficiency of the tip and increase force pressure by the tip on tissue such as to decrease ultrasonic energy required to cause the needle to penetrate hard tissue. The needle tip may be angled so as to define a cutting plane having a wide upper arc and a thin lower arc.

摘要： Apparatus for inserting intraocular lenses (IOLs) into eyes are disclosed. The apparatus comprises an insertion tube, and an injector rod having a distal tip capable of engaging an intraocular lens. A rotating assembly is provided to controllably rotate the rod as it moves distally through the insertion tube. The rotation of the injector rod is imparted to the IOL in such a manner that the IOL is also rotated as it moves through the insertion tube. The degree of rotation of the IOL is controlled to place the IOL in an orientation for final implantation in the eye with reduced risk of damaging the eye. Methods for inserting an IOL into an eye using such apparatus are also disclosed and are within the scope of the present invention.
