Scleral Fixation of Carlevale Intraocular Lens in Children: A Novel Tool in Correcting Aphakia With No Capsular Support.

Abstract

To report the clinical outcomes of the use of a novel, specially designed, scleral-fixated intraocular lens (IOL) for the correction of aphakia in the absence of capsular support of variable etiology in children. This is a retrospective, noncomparative, interventional case series of five eyes of five consecutive patients who underwent three-port pars plana vitrectomy and scleral fixation of the IOL. Inclusion criteria were at least 6 months of follow-up in children who underwent vitrectomy and IOL placement for aphakia and inadequate capsular support. Patients were excluded from the analysis if there was a previous open globe injury or any other ocular comorbidity such as macular pathology or previous surgery for retinal detachment, glaucoma, corneal transplantation, or strabismus. The median follow-up period was 9 months (range: 7-13 months). The median age was 8 years (range: 2-10 years), and the male-to-female ratio was 5 to 0. Mean postoperative best-corrected visual acuity (VA) at the last follow-up visit was 20/32 (0.26 ± 0.32 logMAR [mean ± standard deviation]), improving from a mean baseline uncorrected VA of 20/800 (1.6 ± 0.7 logMAR), a statistically significant change (P = .003). The uncorrected postoperative VA was 20/63 (0.54 ± 0.37 logMAR). No significant postoperative complications were noted and all patients had good IOL position at the end of the follow-up without IOL capture. The mean tilt in four eyes (the 2-year-old was excluded from the analysis) was 2.1 ± 1.9 degrees. None of the patients required reoperation. The present study represents the first to date in evaluating the use of a scleral-fixated IOL in patients with aphakia and in pediatric patients with inadequate capsular support. The technique is safe and provides excellent postoperative IOL fixation without IOL capture in any of the patients studied. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:94-101.].
