Abstract
In various embodiments, an ophthalmic surgical instrument may include an aspiration tube, an irrigation/aspiration tip (formed of a first material such as plastic), and a patch, coupled to the irrigation/aspiration tip, made of a second material (e.g., silicone) having a higher coefficient of friction than the first material. In some embodiments, the patch may be placed on the irrigation/aspiration tip in a position to allow a user of the irrigation/aspiration tip to manipulate an intraocular lens (IOL) through contact between the patch and the IOL. For example, the patch may be positioned on a side of the irrigation/aspiration tip opposite an aspiration port or on a distal end of the irrigation/aspiration tip. In some embodiments, the patch may be formed separately and coupled to the irrigation/aspiration tip through an adhesive or may be molded onto the irrigation/aspiration tip. In some embodiments, the patch may include features to increase friction.
