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

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.

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.

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.

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.
