Purpose: To assess the medium-term efficacy and safety of treating nucleus and intraocular lens (IOL) dislocation with pars plana vitrectomy (PPV) combined with iris-claw IOL implantation.
Setting: Department of Ophthalmology, University of Lyon 1 Claude Bernard, Lyon, France.
Design: Retrospective case series.
Methods: The study comprised consecutive patients without capsule support having PPV combined with iris-claw IOL implantation for posterior dislocation of the nucleus or IOL between 2008 and 2012. The preoperative, intraoperative, and postoperative data were retrospectively analyzed. Patients were invited to a prospective final examination at least 6 months postoperatively.
Results: The study enrolled 32 eyes (31 consecutive patients). The dislocation was spontaneous in 8 cases and traumatic in 24 (intraoperative 17 cases, contusive 7 cases). The iris-claw IOL was on the anterior side of the iris in 19 cases and on the posterior side in 13 cases. The mean corrected distance visual acuity at the end of follow-up was 20/40 or better in 22 patients (69%). The mean spherical equivalent was +8.20 (SD)±6.03 diopters (D) preoperatively and -0.51±1.14 D postoperatively. The median endothelial cell loss was 20.5% over the first 3 months. The complications were cystoid macular edema (n=8), retinal detachment (n=4), transient intravitreal hemorrhage (n=4), secondary glaucoma (n=2), and choroidal detachment (n=1). The final examination was performed in 27 eyes.
Conclusion: Treatment of nucleus and IOL dislocation with PPV combined with iris-claw IOL implantation was effective and safe over the medium-term.

Introduction: Cataract is a leading cause of visual impairment globally and in Malaysia, with surgery being the definitive treatment. While intracapsular cataract extraction (ICCE) is now less commonly performed due to advancements in surgical techniques, it remains essential in specific cases, such as those with weak zonular support. This study aims to evaluate the incidence, clinical profiles, and visual outcomes of patients who underwent ICCE, with or without intraocular lens (IOL) implantation, at Hospital Melaka, Malaysia, over the past decade.

: To compare the clinical outcome of suture and sutureless iris fixation techniques for dislocated intraocular lenses (IOLs). : Retrospective cohort study including patients who underwent surgery for late IOL dislocation over a 10-year period. IOL repositioning was achieved either by suturing the original IOL to the iris using the Siepser slipknot technique or by replacing it with a retropupillary sutureless iris claw IOL.

Article Synopsis
- The study evaluates the complication rates of various intraocular lens (IOL) placement methods in adults who lack adequate capsular bag support.
- It analyzes data from 15 studies involving 1,247 eyes, finding that iris fixation had a lower overall complication rate (4.4%) compared to anterior chamber (AC) placement (7.4%) and scleral fixation (7.4%).
- Common complications included transient corneal edema primarily in AC placement (29.9%) and higher rates of vitreous hemorrhages and IOL dislocation with scleral fixation.

Article Synopsis
- Iris fixated lenses are used to help people who have eye problems like Aphakia and loose lenses.
- Sometimes, these lenses can make the pupil stay small after surgery.
- We found a new way to fix a serious eye issue that happens with these lenses, which makes the surgery easier and faster while helping the patient see better sooner.
