Intraocular lens (IOL) dislocation is not an uncommon complication and often requires surgical intervention, depending on the status of capsular bag support. Conventionally, posterior dislocation of a foldable IOL or the IOL-bag complex warrants their removal as foldable IOLs are not ideal for sulcus placement. The technique presented here describes using quadrilateral sutures to refix looped haptic IOLs at the ciliary sulcus with or without a bag complex.

Aim: To present a technique of transcapsular scleral fixation of the standard capsular tension ring (CTR) through equatorial capsulotomy and in-the-bag intraocular lens (IOL) implantation in subluxated lenses.
Methods: This retrospective consecutive case series included patients with subluxated lenses by more than 180 degrees who underwent lens extraction, transcapsular scleral fixation of the standard CTR through equatorial capsulotomy, in-the-bag IOL implantation and with at least 6mo follow-up. Preoperative and postoperative best corrected visual acuity (BCVA), intraocular pressure (IOP), complications, and postoperative IOL tilt and decentration were recorded.
Long-term Follow Up of a Complex Case of Foldable Capsular Vitreous Bag Implantation.
Retin Cases Brief Rep
December 2024
Liverpool Ocular Oncology Research Centre, Department of Molecular and Clinical Cancer Medicine, University of Liverpool, Liverpool, UK.
Purpose: The Foldable Capsular Vitreous Bag (FCVB) implant is useful in maintaining ocular structure in cases of chronic hypotony secondary to trauma or repeated surgery. There are few published reports of long-term outcomes and no indication of the chronic cellular changes of the adjacent tissues associated with FCVB implantation. We describe one of few FCVB cases in the UK and present histological findings associated with it following secondary enucleation.

Introduction: We conducted an evaluation of capsular bag performance of the Clareon CNA0T0 intraocular lens (IOL), focusing on postoperative anterior chamber depth (ACD), IOL tilt, and IOL decentration.
Methods: Inclusion criteria were bilateral age-related cataract and the ability to provide informed consent. Exclusion criteria were prior surgeries, combined surgeries, and conditions posing a risk for postoperative capsular bag instability.
Mefunidone Inhibits Inflammation, Oxidative Stress, and Epithelial-Mesenchymal Transition in Lens Epithelial Cells.

Eye Center of Xiangya Hospital, Central South University, Changsha, China.
Purpose: Inflammation, oxidative stress, and epithelial-mesenchymal transition (EMT) play crucial roles in forming posterior capsular opacification (PCO), particularly in fibrotic PCO. Here we investigated the protective effects of mefunidone (MFD), a novel compound with potent antifibrotic properties, which could be useful in preventing PCO.
Methods: We utilized an extracapsular lens extraction (ECLE) surgery in mice to simulate the development of PCO in vivo.
