Sutureless 25-Gauge Pars Plana Vitrectomy Combined with Retropupillary Fixation of an Iris-Claw Intraocular Lens

Abstract

Background: The surgical case of a dropped intraocular lens inside the vitreous cavity constitutes a real challenge for the operating surgeon. Herein, we describe a case series where an alternative optical rehabilitation technique for late intraocular lens-bag complex dislocation has been used. Methods: A modern vitrectomy device was used to remove the capsule with the dropped intraocular lens using sutureless 25-gauge pars plana vitrectomy. To ensure a better aesthetic result, with faster patient recovery and a reduced number of operations, the whole procedure was performed during the same operating session; an iris-claw intraocular lens for aphakia was selected for implantation. The implant was passed behind the constricted iris with the concave surface facing it. The lens was grasped with the manufacturer’s holding forceps and fixed onto the posterior surface of the iris using the special enclavation needles. Results: We have operated 12 eyes in two different clinical centres successfully, with minimal intra- and/or postoperative complications. Conclusion: We believe that this is a viable solution for the visual rehabilitation of patients, who would otherwise need more than one operation for a lens exchange.
