Scleral fixation of Carlevale intraocular lens: A new 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, the Carlevale intraocular lens (carlevale IOL, Soleko, Italy) for the correction of aphakia in the absence of capsular support of variable etiology. This retrospective, non-comparative study included 169 eyes of 169 consecutive patients who underwent 3-port pars plana vitrectomy and scleral fixation on Carlevale IOL. Inclusion criteria were at least 6 months' follow-up period, patients > 18 years old who underwent vitrectomy and Carlevale IOL placement for aphakia and inadequate capsular support. The median follow up period of 9 months (range 6-18 months). Mean post-operative BCVA at the last follow-up visit was 20/25 (0.09 ± 0.1 LogMAR), improving from a mean baseline BCVA of 20/80 (0.58 ± 0.49 LogMAR), a statistically significant change (p = 0.0001). Regarding the post-operative complications, a transient rise in the IOP was observed in 28 patients (16.5%) and mild vitreous hemorrhage was observed in the immediate post-operative period in eight eyes (4.7%) and it spontaneously resolved within 3 weeks. All patients demonstrated good IOL position at the end of the follow-up without IOL capture. None of the patients required re-operation. The present study represents the largest to date in evaluating the use of carlevale IOL in patients with aphakia and inadequate capsular support. The technique is safe and provides excellent post-operative IOL fixation without IOL capture in any of the patients studied.
