Schematic figure demonstrating surgical steps of two-way adjustable double-knots (TADK) intrascleral fixation with single sclerotomy looping (SSL) technique for IOL fixation. SSL(A-C). A, The 30-gauge needle with the leading end of 8 − 0 polypropylene thread was introduced into the eye 2.5 mm from the limbus at the fixation site. The tip of the 30-gauge needle passed through the closed loop of the haptic from back to front. B, The 23-gauge gripping forceps grasped the thread out of the 30-gauge needle from the front of the haptic. The 30-gauge needle was drawn back a little bit. C, The 30-gauge needle was forwarded to the front of the haptic. The 23-gauge gripping forceps delivered the leading end of the thread back to the tip of the 30-gauge needle. D, The 30-gauge needle was withdrawn from the eye and the leading end of the polypropylene thread was externalized from the same sclerotomy at the fixation site. TADK (e-f) E, Two 3-1-1 overhand knots with an interval of 1.5 mm were made with both ends of the thread 3.0 mm from the sclerotomy. F, The leading end of the thread was pulled to lead both knots entering the scleral tunnel and the other end of the thread was left at the beginning of the tunnel
