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 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.

Mentions: It was not necessary to extend the corneal incision because the diameter of the insertion tip was only 2 mm. The trailing haptic was purposefully left outside the eye and secured with the other end of the 10-0 Prolene suture before insertion into the posterior chamber (Fig. 4). Tension was adjusted as necessary to center the IOL. The needle of each arm of the suture was passed through the scleral bed underneath the flap to form a loop. The needle was then cut off and the suture end was firmly tied to the loop. The scleral flap was then securely repositioned with a single 10-0 nylon suture.
