Abstract Purpose Comparing two different sutureless scleral fixation techniques. Methods A retrospective study of patients who underwent sutureless scleral fixation IOL from October 2013 to May 2018 at “Luigi Sacco Hospital”, University of Milan. Comparison between two groups: Group 1 implanted with a 3-piece ALCON-MA60AC and group 2 implanted with a newly developed single-piece foldable IOL SOLEKO FIL-SSF. Patients underwent a complete preoperative ophthalmic assessment and post-operative evaluation at 1, 3, and 6 months. Vitrectomy was performed in all cases. The two groups were compared for age, axial length, and lens status at baseline. Visual acuity, refractive results, surgical time, and post-operative complications were recorded. Results Thirty-one eyes were included: group 1, 15 eyes of 15 patients, and group 2, 16 eyes of 14 patients. No difference was found in visual acuity. Mean refractive error was 1D in both groups (group 1 1.01D, group 2 1.09D), but spherical equivalent was more often moved toward negative values and induced astigmatism was greater in the 3-piece group (group 1 1.91D [SD ± 2.07], group 2 0.67D [SD ± 0.88] P = 0.04). Surgical procedure was faster in group 2 (mean time difference 21′, P = 0.01*). New displacement occurred in 5 cases (33%) of group 1 and in no cases of group 2 (P = 0.01*). Post-operative bleeding was registered only in group 1 (20%), but the difference was not statistically significant. Conclusions The group 2 IOL gives in our sample better results due to less post-operative astigmatism and reducing dislocation and bleeding during follow-up. Surgical technique appeared easier and faster: the specifically designed IOL seems to be a feasible solution for sutureless scleral fixation. Keywords Sutureless . Scleral fixation . Soleko FIL-SSF .

Key messages Main problem in sutured scleral fixation lens is long-term erosion and breakage of the sutures. Three papers were published recently describing sutureless Soleko FIL-SSF lens implantation and only one of these reported refractive outcomes. This is a retrospective study concerning surgical techni
