Clinical experience of two sutureless intrascleral fixation techniques for secondary intraocular lens implantation

Introduction: To evaluate the outcome of the modified Carlevale IOL fixation technique, using two different vitrectomy ports (23- vs. 27-gauge) as anchor fixation.Methods: Retrospective, consecutive study of 282 eyes (282 patients) who underwent a secondary IOL implantation using the Carlevale IOL (Soleko IOL Division, Italy) with two anchor haptics for intrascleral implantation with either 23- or 27-gauge (G) port.Results: Transient postoperative ocular hypotonia (intraocular pressure & LE; 5mmHg) was observed less in the 27-G group (13 vs 4 patients, p=0.057) three requiring additional tunnel sutures (2 cases for 23-G; 1 case 27-G)Postoperative vitreous hemorrhage was recorded more often in the 23-G group (8 vs 1 patient, p=0.034), but all cases in both groups resolved without intervention. Visual acuity did improve postoperatively in the two groups. No postoperative complications such as retinal detachment, endophthalmitis, IOL dislocation tiltwere observed in the follow-up. Conclusion: The 27-G modified technique for sutureless intrascleral implantation is simple and effective and causes less postoperative hypotony.
