    Abstract:
    PURPOSE: To compare capsular bag stability and posterior capsule opacification (PCO) of a plate-haptic intraocular lens (IOL) and a standard three-piece open-loop-haptic IOL of the same acrylic material. METHODS: In this randomised bilateral patient-masked and examiner-masked study, each patient received a microincision cataract surgery IOL (MICS IOL; Acri.Smart 46S=CT SHERIS 209M) in one eye and a small incision cataract surgery IOL (SICS IOL; AcriLyc 53N = CT 53N, both Carl Zeiss Meditec AG, Germany) as a control in the contralateral eye. Follow-up examinations were performed 1 h, 1 week, 1 month, 1 year and 3 years postoperatively. Anterior chamber depth (ACD) was measured and retroillumination images were performed at all postoperative follow-ups. Furthermore, uncorrected and corrected distance visual acuity, autorefraction and subjective refraction were assessed. RESULTS: In total, 50 eyes of 25 patients were included. The ACD difference between the MICS IOL and the SICS IOL was not significant at any time point (p>0.05). Distance-corrected visual acuity at the 3-year follow-up was similar and not significantly different between the groups (p=0.48). Mean AQUA score in the MICS IOL group and in the SICS IOL group at the 3-year follow-up was 2.3 (SD ±2.3) and 2.1 (SD ±2.2), respectively (p=0.79). CONCLUSIONS: The investigated hydrophilic acrylic plate-haptic MICS IOL with a hydrophobic surface showed comparable results concerning capsular bag stability and PCO rates up to 3 years compared with a SICS IOL of the same material.
