FIL-SSF Carlevale intraocular lens for sutureless scleral fixation: 7 recommendations from a serie of 72 cases. MICA study (Multicentric Study of the Carlevale IOL).

PURPOSE

Lacking a standard technique, the surgical management of aphakia without capsular support remains to be optimized. The goal of this study is to analyze results for the Carlevale FIL-SSF intraocular lens and propose surgical recommendations.

PATIENTS AND METHODS

The P1.5 Collective performed a retrospective analysis, with a minimum follow-up of 6 months, of the records of 72 implantations of the Carlevale FIL-SSF intraocular lens, specifically designed for sutureless scleral fixation in the ciliary sulcus.

RESULTS

The most common indication was exchange of a posterior chamber intraocular lens (70.8%). The surgery lasted a mean of 53.4minutes due to the creation of scleral flaps. The implant was damaged in 12.5% of cases. Visual acuity was improved in 83.3% of cases. The postoperative spherical equivalent was -0.3 diopters, with no change in corneal astigmatism. The implant was centered and stable in all cases. Two cases (2.8%) of cystoid macular edema were observed and resolved over six months.

DISCUSSION

A number of advantages of the Carlevale FIL-SSF intraocular lens make it a safe and effective solution for correction of aphakia in the absence of capsular support. It requires a longer than usual surgical procedure, and the implant must be handled with care. From their experience, the authors propose 7 recommendations to accelerate the learning curve.

CONCLUSION

In light of the results of this study, we propose the Carlevale FIL-SSF intraocular lens as the new standard for the correction of aphakia without capsular support, but other studies are necessary to determine its exact place within the heirarchy of other available techniques.
