New compound curved needle TG6-C PLUS.
The benefits of a compound curve needle design will be seen readily when used as suggested. The surgeon will be able to position the needle repeatedly and accurately between the wound edges from needle entry through tissue, to exit to the opposite side of the wound. Continuous or interrupted corneal wound closure can be done consecutively without varying more than a few tenths of a millimeter in the positioning of the needle from bite to bite. During retrieval the compound curve needle has yet another advantage. The flat curve of the distal needle body minimizes the tissue distortion as the needle body is pulled through. The wound remains in close apposition. In wound closure, though an important and essential attribute of a surgical needle is its "sharpness", sharpness eventually reaches a maximum. The very sharp needles such as the new EthiconTM TG PLUS needles, have such little tactile feedback that shape and needle strength as exemplified by the compound curvature design become of primary importance. These combinations provide the consistent and accurate needle passage necessary for corneal wound apposition, with all of its optical as well as anatomic consequences, in the final outcome of contemporary keratoplasty and cataract procedures.
