Purpose of the study was to evaluate the rotational stability of the ACR6-DSE® intraocular lens (IOL) and the IDEA 613 XC® IOL.

In this prospective study patients with age-related cataract were included. On the day of pre-operative assessment, patients underwent a full ophthalmic exam and optical biometry was performed using the IOL-Master 500 (Carl Zeiss Meditec AG, Germany). Retroillumination photography was performed 1 hour and 3 months after surgery with a high-resolution digital retroillumination imaging system. Additionally, autorefraction in IOL mode (Topcon RM 8800, Topcon Corporation, Japan), and a full slitlamp examination were performed three months postoperatively.
In total, 60 patients were included in this study and 18 patients were lost to follow-up. In total, 20 patients in the large diameter IOL group (Idea group) and 22 patients in the small diameter group (ACR6 group). Absolute rotation in the small diameter group and the large diameter group was 4.35 (SD: 3.99°; range: 0.25° to 17.75°) and 3.01°(SD: 2.36°; range: 0.10° to 7.80°), respectively. The difference between the two IOLs was not found to be significant.
The difference between the IOLs was not found to be significant. However, it was shown that in the small diameter IOL group rotation of more than 10° occurred in some eyes, whereas this was not the case in the large diameter IOL group. FINANCIAL INTEREST: NONE
