Sutureless Intrascleral One-piece Intraocular Lens Fixation for Ectopia Lentis in Marfan Syndrome.

PURPOSE: To evaluate safety and clinical outcomes of the sutureless intrascleral one-piece intraocular lens (SSF IOL) fixation in patients with Marfan syndrome (MFS) presenting with ectopia lentis.

METHODS: This retrospective, longitudinal, non-comparative case series was a multicenter study involving Ophthalmology Departments at three tertiary care centers in Italy. Fifteen eyes from 10 patients (4 males, 6 females; mean age 29.13 ± 16.96 years) diagnosed as having Marfan syndrome underwent lensectomy and implantation of the SSF one-piece IOL (FIL SSF; Soleko). Patients were followed up for 12 months postoperatively. Primary outcomes included corrected distance visual acuity (CDVA), IOL tilt (35-MHz ultrasound biomicroscopy), and endothelial cell density (ECD). Intraoperative and postoperative complications were recorded.

RESULTS: All surgeries were performed uneventfully, and no intraoperative complications occurred. CDVA improved significantly from 0.50 to 0.09 logarithm of the minimum angle of resolution (logMAR) (P = .0001). At 12 months postoperatively, the mean IOL tilt was 2.89 ± 0.91 degrees, indicating good centration and stability. No cases of IOL dislocation were reported. ECD showed a statistically significant mean reduction of 257.4 ± 138.2 cells/mm2 (P < .0001), although no corneal decompensation was observed. The postoperative complications included one case of macular edema with subsequent development of an epiretinal membrane and one case of haptic exposure.

CONCLUSIONS: The SSF implantation of a single-piece IOL appears to be a viable and reproducible option for the successful surgical management of ectopia lentis in patients with MFS.
