Purpose

To evaluate and compare the post-operative outcome of two different IOL models (ZA9003, J&J, USA and PU6AS, Kowa, Japan) using the Yamane technique.

Setting

Kepler University Clinic, Ophthalmology department, Linz, Austria

Methods

Patients who underwent sutureless scleral fixated IOL implantation between 2018 and 2023 were included in this study. Patients were divided into two groups, group A receiving a hydrophobic acrylic IOL with PMMA haptics (Tecnis ZA9003), group B receiving a hydrophobic soft acrylic IOL with PVDF haptics (KOWA PU6AS). Follow-ups were performed one day and six weeks after surgery. Study examinations included optical biometry (IOLMaster700, Carl Zeiss Meditec AG, Germany), corneal tomography including tilt measurement (Casia2, TomeyCorp, Japan and MS-39 + Osiris, CSO, Italy), autorefraction, subjective refraction and corrected as well as uncorrected visual acuity.

Results

In total, 40 patients were included in this study.

Preliminary data shows a difference regarding mean absolute tilt (Group A: 8.84±3.92° and Group B: 6.50±3.70 °). Mean absolute decentration was lower in group B than group A (0.43±0.22 mm versus 0.54±0.44 mm, respectively). The postoperative ACD in group A was higher compared to group B (5.45±0.43 mm versus 5.26±0.31 mm). Group A provided a lower mean absolute error (0.73±0.89 versus 1.18±0.92), as well as a better best corrected distance visual acuity (BCDVA) (0.04±0.20 logMAR vs. 0.24±0.43 logMAR).

Conclusion

Group B seems to provide more stable results in terms of tilt as well as decentration, however with a lager mean absolute error as well as a lower BCDVA. A larger data-set will be presented at the meeting.
