We developed an injector with a tip that matches the shape of the ciliary sulcus (Ciliary Sulcus Pad Injector) and is used in ciliary sulcus suture fixation of intraocular lenses. The injector is inserted through the corneal incisions and slid along the posterior surface of the iris to the opposite side. When the tip of injector is fitted in the ciliary sulcus, the plunger is pressed, causing the needle to pierce the ciliary sulcus. A suture is inserted in the ciliary sulcus without direct observation. In 91.4% of cases, the needle correctly pierced the ciliary sulcus in a single attempt. The difference between the preoperative expected refractive power and the postoperative spherical equivalent power was −0.63 diopter 6 months after surgery.
