Purpose: To evaluate the clinical outcomes of sutureless capsular bag and intraocular lens (IOL) fixation with flattened, flanged intrascleral fixation technique in patients with large zonular dialysis.
Methods: Fifty-five eyes of 51 patients who underwent flattened flanged intrascleral capsular bag and IOL fixation and optic capture for traumatic cataract, subluxated cataract, and pseudoexfoliation syndrome (PEX) with zonular dialysis greater than 180° were included in the study. The main difference of this technique from the Yamane technique is that it has a flattened flange with sharp borders at the haptic tip. Uncorrected visual acuity, corrected distance visual acuity (CDVA), astigmatism, endothelial cell loss, IOL tilt, and intraoperative and postoperative complications were evaluated.
Results: The mean age of the patients was 57.4 ± 15.1 years (range 18-83). Of the patients, 28 (55%) were male and 23 (45%) were female. The mean duration of follow-up after surgery was 19.3 ± 6.5 months (range 12-36). The mean preoperative and postoperative CDVA were 0.71 ± 0.16 logMAR and 0.13 ± 0.20 logMAR, respectively (p < 0.001). The mean preoperative and postoperative astigmatism were 2.0 ± 1.4 D and 1.0 ± 0.7 D, respectively (p < 0.001). The mean IOL tilt was 5.7° ± 5.2°. The mean endothelial cell loss was 9% (range 0.9-19.5). Anterior capsular phimosis was developed in 2 eyes (4%).
Conclusion: The flattened flanged intrascleral technique of the capsular bag combined with optic capture provides good visual outcomes, robust capsular bag-IOL fixation, and minimal adverse events. However, further studies with more patients are needed for long-term results.

Purpose: To evaluate demographic profile, risk factors and outcomes following intraocular lens (IOL) exchange surgery for late decentration of IOLs in the dead bag syndrome DESIGN: Prospective, interventional case series PARTICIPANTS: 46 eyes (43 patients) with late decentration/dislocation of IOLs and spontaneous posterior capsule rupture in a clear and relatively intact capsular bag. None of the eyes had significant zonular weakness.

Background: Pseudophakic cystoid macular edema (CME) following primary anterior-chamber intraocular lens (ACIOL) implantations is commonly seen. Intravitreal triamcinolone acetonide (IVTA) injections have shown significant improvement in visual acuity and retinal thickness in refractory pseudophakic CME. Pseudohypopyon following IVTA injection is a known entity.

In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods. Finite element models included zonules, ciliary body, capsular bag, and an IOL with two open-loop haptics were built.

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.
