Suture fixation technique for a single-piece foldable closed-loop intraocular lens.

Park CH, Lee SJ - Korean J Ophthalmol (2008)

Bottom Line: This new surgical technique was performed in seven patients.The clinical outcomes were encouraging.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 IOL.

ABSTRACT

Purpose: We describe a suture fixation technique for a single-piece foldable acrylic closed-loop intraocular lens (IOL) (C-flex, 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 IOL.

Figure 6: The broad arc of distal haptic-tissue contact in the two-point suture fixation technique.

Mentions: In all cases, point B of the haptic was selected as a suture placement site. It is impossible to achieve haptic-tissue contact due to the short diameter of the haptic spread (10 mm) at point B. However, the diameter of the haptic spread increases gradually toward the distal portion of the haptic, and the diameter of the haptic spread at point A (12 mm) exceeds the mean diameter (11 mm) of the ciliary sulcus. Consequently, a portion close to the ends of the haptics contacts the tissue in a broad arc, this presumably results in increased stability of the IOL (Fig. 6).
