An instrument to assist in resection surgery consists of a telescoping hook within a second hook that can be spread a calibrated distance. Its primary purpose is to maintain a constant tension and an accurate measure of tendon length during suture passage. Additionally, the grooved distal hook supports the needle and protects the globe from needle trauma.
