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.

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.

Figure 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.

Mentions: All surgeries were performed by a single surgeon. Two fornix-based conjunctival peritomies were made 180 degrees apart (usually from 2 to 4 o'clock and from 8 to 10 o'clock) followed by the construction of 3×3 mm partial thickness triangular limbus-based scleral flaps. One arm of a double-armed 10-0 Prolene (Ethicon, STC6) suture on a long straight needle was passed 1 mm posterior to the limb ab externo underneath the scleral flap and docked into a 26-gauge needle inserted in a similar fashion from the opposite side. The 26-gauge needle with the 10-0 Prolene suture was then withdrawn, resulting in the 10-0 Prolene suture bridging the posterior chamber. The suture was then externalized through a 3.0 mm beveled corneal incision (12 o'clock position) using a Sinskey hook and cut. Before placing the IOL in the injector, one end of the 10-0 Prolene suture was threaded through the injector and tied at point A on the leading haptic. The IOL was then loaded into the injector and the leading haptic was inserted into the posterior chamber (Fig. 3).
