Patent ID: 8545462

Claim:
An ophthalmic surgical instrument, comprising: an aspiration tube defining an aspiration channel, having a proximal end and a distal end; an irrigation/aspiration tip, formed of a first material, coupled to the distal end of the aspiration tube, wherein the irrigation/aspiration tip has a closed distal end and has at least one external aspiration port, entirely on a first side of the irrigation/aspiration tip, in fluid communication with and forming an outermost portion of the aspiration channel; and a patch coupled to the irrigation/aspiration tip, wherein the patch is made of a second material having a higher coefficient of friction than the first material, wherein the patch is entirely on a second side of the irrigation/aspiration tip to allow a user of the irrigation/aspiration tip to manipulate an intraocular lens (IOL) through contact between the patch and the IOL; wherein the first side of the irrigation/aspiration tip lies entirely on one spatial side of a plane containing a longitudinal axis of the tip and the second side lies entirely on the opposing spatial side of the plane.
