Aim:
To introduce a novel technique for transscleral fixation of the posterior chamber intraocular lens (PC-IOL) that requires no sutures on the IOL haptics.
Methods:
Instead of suturing polypropylene onto the IOL haptics, the method simply winds the thread on the haptics. Fifteen eyes of 15 patients underwent this technique and were followed up for more than 18mo. Surgical outcomes and post-operative complications were evaluated and compared with those of the conventional transscleral fixation method.
Results:
Postoperative cylinder was significantly lower in the thread winding group than in the conventional transscleral fixation method group (-1.02±0.46 diopters vs -1.57±0.77 diopters; P=0.01). Further, no postoperative complications, such as optic capture, IOL dislocation, and hyphema, were detected in the thread winding group.
Conclusion:
We believe that our thread winding technique is better than previously reported methods because it is simple, mechanically stable, and free from suture-related complications.
