Published by John Wiley & Sons Ltd Purpose: To report the feasibility and long-term safety of lensectomy and iris-claw intraocular lens (IOL) implantation to treat children with severe ectopia lentis in a paediatric tertiary hospital. Methods: Prospective cohort study of 21 eyes from 12 patients with severe ectopia lentis and visual acuity <20/63. All eyes underwent 23-gauge pars plana vitrectomy, lensectomy, iridectomy and Artisan IOL implantation in the anterior chamber with iris-claw enclavation via pars plana. Mean age at surgery was 8.0 ± 5.3 yo (range 3–17 years). A full ophthalmologic examination including best-corrected visual acuity (BCVA), biomicroscopy, intraocular pressure (IOP) measurement, fundus evaluation and central endothelial cell count (cECC) was performed pretreatment, at 3 months' postsurgery, and every 6 months thereafter. Ultrasound biomicroscopy (UBM) was performed 12 months after surgery. Results: Mean follow-up was 39.3 ± 13.0 months. Best-corrected visual acuity (BCVA) (mean ± SD) improved from 0.91 ± 0.29 logMar preoperatively to 0.18 ± 0.23 logMar at final follow-up (p < 0.0001). Mean distance from the endothelium to the anterior IOL surface after surgery was 3.11 ± 0.61 mm. Postsurgically, cECC loss was 5.04% ± 9.58% with an annual cECC loss rate of 3.16% ± 4.46%. One patient developed IOL dislocation and retinal detachment after severe ocular contusion requiring vitrectomy, IOL refixation and gas tamponade. Another patient developed cystoid macular oedema, managed with intravitreal dexamethasone. Conclusion: This technique is both feasible and effective to manage severe ectopia lentis in children. Lifetime ophthalmic follow-up including cECC measurement, IOL position monitoring and fundus examination is mandatory in these patients.
