Abstract

PURPOSE: We describe a suture fixation technique for a single-piece foldable acrylic closed-loop intraocular lens (IOL) (C-flex(TM), Rayner). METHODS: In our experimental model analyzing the stability of acrylic haptics, we confirmed that the IOL could be in counterpoise without tilt using only a two-point fixation. This new surgical technique was performed in seven patients. RESULTS: The unique haptic design allows easy and secure suture fixation. The clinical outcomes were encouraging. CONCLUSIONS: It is conceivable that better stabilization can be achieved by the broad arc of distal haptic-tissue contact, in addition to suture fixation, using our surgical technique with the C-flex(TM) IOL.

  Fig. 3 One free end of the suture is passed from the 8 o'clock position through the insertion tip of the injector and tied to the leading haptic. The IOL is loaded into the injector after the suture is pulled out with forceps and tied at the leading haptic.

  Fig. 4 The other free end of the suture is passed from the 2 o'clock position and tied to the trailing haptic outside the eye.
