Objective: One hydrophilic acrylic intraocular lens (IOL) with enhanced 360° sharp optic edge design (Rayner C-flex) was evaluated three years postoperatively to investigate functional results and development of secondary cataract in comparison to the former Centerflex IOL.
Methods: In a prospective clinical setting, a C-flex IOL was implanted in one eye of 42 patients (mean age: 71.5±8.2 years). Besides functional results, retroilluminated photographs were evaluated 6, 12, 24 and 36 months after surgery using the EPCO analysis program and compared to a matched group of Centerflex patients.
Results: One month postoperatively, mean best corrected distance visual acuity increased from 0.22±0.23 [logMAR] to 0.08±0.12 [logMAR]. Three years after implantation, slightly decreasing interim results were noted: 0.16±0.28 [logMAR] (n=25). Within three postoperative years, the C-flex IOLs showed less secondary cataract development compared to the Centerflex group.
Conclusions: The enhanced 360° sharp optic edge design reduced posterior capsule opacification in the long-term follow-up by preventing lens epithelial cell migration along the optic-haptic junctions.
