Implantation of foldable posterior chamber intraocular lens in aphakic vitrectomized eyes without capsular support

Abstract

Purpose: To evaluate the outcomes of three different surgical techniques for foldable posterior chamber intraocular lens (PCIOL) implantation in vitrectomized eyes without capsular support. Methods: A total of 60 patients with aphakic and vitrectomized eyes without capsular support were enrolled. All patients underwent three-piece foldable PCIOL implantation into the posterior chamber through a small corneal incision. Transscleral fixation (TSF), iris fixation (IF), and intrascleral tunnel fixation (ISF) surgical techniques were performed. Results: Postoperative PCIOL subluxation or dislocation occurred in one case in the TSF group and two cases in the ISF group. Intraoperative PCIOL dislocation occurred in two patients in the IF group. The incidence of temporary postoperative complications, such as mild intraocular hemorrhage and cystoid macular edema, was higher in the ISF group. No statistically significant difference in PCIOL-related astigmatism was observed between groups. Visual acuity improved in all groups. Conclusions: Postoperative outcomes were comparable between TSF, IF, and ISF for PCIOL in vitrectomized eyes without capsular support.

Long-term outcome of scleral-fixated intraocular lens implantation without conjunctival peritomies and sclerotomy in ocular trauma patients

“…Conjunctiva and sclera preservation are particularly desirable in those population who may require surgery to control traumatic glaucoma, and helps to reduce postoperative dry eye discomfort. Second, clear corneal incision reduces the occurrence of surgicallyinduced corneal astigmatism [20]. Third and most importantly, the transscleral suture passing through the sclera can be rapidly fixed without any knots and thus precludes knot-related complications.…”

Long-term outcome of scleral-fixated intraocular lens implantation without conjunctive peritomies or sclerotomy in ocular trauma patients

“…Several surgical approaches for SFIOL implantation have been proposed. All methods involve imbedding the suture knot under the scleral flap, in addition to other complex maneuvers [17,18] In this study, we demonstrate a new approach for transscleral IOL implantation involving minimally invasive knotless IOL fixation. The advantages of this approach go beyond those subsequently listed.…”

“…Conjunctival preservation is particularly desirable in this population, since prior or subsequent surgery may be required to control traumatic glaucoma, and because it reduces postoperative dry eye discomfort. Second, use of a foldable IOL contained in the injector reduces the size of the clear corneal incision, a crucial aspect of the technique that reduces the occurrence of surgically-induced corneal astigmatism [17]. Third and most importantly, the transscleral suture passing through the sclera can be rapidly fixed without any knots and thus precludes knot-related complications.…”
