Long-term Outcomes and Complications of the New Carlevale Sutureless Scleral Fixation Posterior Chamber IOL.

PURPOSE
To evaluate the visual outcomes and possible complications of a new foldable sutureless scleral fixation intraocular lens (SSF-IOL), the Carlevale IOL (Soleko).


METHODS
The SSF-IOL, which has two T-shaped self-blocking plugs on each haptic, was inserted into the posterior chamber. Both haptics was grabbed through two sclerotomies and the two short arms were blocked under the scleral flap, without any suture. A complete clinical evaluation was done preoperatively and at 3, 6, and 12 months postoperatively.


RESULTS
A total of 54 eyes of 50 consecutive patients were retrospectively analyzed. The mean corrected distance visual acuity was 0.93 ± 0.61 logMAR preoperatively and improved to 0.42 ± 0.34 logMAR at 3 months, 0.42 ± 0.37 logMAR at 6 months, and 0.38 ± 0.38 logMAR at 12 months postoperatively (all P < .0001). The mean corneal endothelial cell density decreased from 1,725.37 ± 528.06 to 1,612.81 ± 522.91 cells/mm2 at 12 months postoperatively (P < .0001). The mean IOL tilt value was 3.1 ± 1.1° at 12 months postoperatively. The authors observed 6 cases (11.1%) of intraoperative rupture of the IOL haptics, 4 cases (7.4%) of early hyphema, 4 cases (7.4%) of macular cystoid edema, 2 cases (3.7%) of haptic exposure under the conjunctiva, and 1 (1.8%) late retinal detachment.


CONCLUSIONS
This newly introduced surgical technique provided promising results regarding efficacy and safety. Complications occurred in a few cases and were successfully managed. The Carlevale IOL seems to be a surgical solution combining the advantages of an easy and minimally invasive implantation with a good functional recovery with minimal complications.
