Modified Carlevale Intraocular Lens Fixation Technique: Two Vitrectomy Ports As Lens Plug Fixation Sites

Retina. 2023 Nov 1;43(11):2034-2036. doi: 10.1097/IAE.0000000000003338.

Abstract

Purpose: To describe and evaluate the effectiveness of the modified Carlevale intraocular lens (IOL) fixation technique, using two vitrectomy ports as lens plug fixation sites.

Materials and methods: This prospective, consecutive, interventional study examined 60 eyes in 60 patients, who underwent 25- or 23-gauge vitrectomy for an IOL subluxation/luxation, lens dislocation, or aphakia, with Carlevale IOL implantation.

Results: Postoperatively, transient ocular hypotension was observed in four eyes. The mean refractive prediction error was -0.27 ± 0.78 diopters. No postoperative complications, such as retinal detachment, endophthalmitis, or IOL dislocation, were observed in the 4-month follow-up.

Conclusion: This new technique may be simple, fast, and effective because of fewer scleral wounds and fewer postoperative complications.
