Purpose

To evaluate and compare the post-operative outcome of two different sceral fixated IOL concepts, the Yamane method (ZA9003, group A, J&J, USA) and the Carlevale IOL (FIL-SSF, group B, Soleko, Italy).

Setting

Kepler University Clinic, Department of Ophthalmology and Optometry, Linz, Austria

Methods

Patients who underwent sutureless scleral fixated IOL implantation between 2018 and 2022 were included in this non-randomised study. Group A included implantation of a 3-piece hydrophobic acrylic IOL with scleral tunnel fixation and group B implantation of a hydrophilic acrylic single-piece intraocular lens with scleral self-anchoring haptics. Study examinations were performed one day and two months after surgery. Study examinations included optical biometry (IOLMaster700, Carl Zeiss Meditec AG, Germany), corneal tomography including tilt measurement (Casia2, Tomey Corp, Japan and MS-39, CSO, Italy) and topography (Osiris, CSO, Italy) autorefraction, subjective refraction and corrected as well as uncorrected visual acuity.

Results

In total 30 patients will be enrolled in this study, the preliminary data of 22 patients is presented. 14 patients were included in group A, 8 patients in group B. Mean absolute tilt for group B was lower than for group A (8.01± 4.02 and 8.84 ±3.93, respectively). Mean absolute decentration and was lower in group B than in group A (0.52±0.28 versus 0.60±0.47). Mean best corrected distance visual acuity was improved in both group postoperatively compared to preoperative measurements (group A: 0.68±0.68 versus 0.45±0.20 logMAR postop; group B: 0.57±0.50 versus 0.25±0.27 logMAR postop).

Conclusions

The preliminary data shows that both groups provide similar results in terms of tilt and decentration. A larger analysis of both groups is necessary and will be provided at the ESCRS meeting.
