Abstract
Aim: To assess the accommodative amplitudes of three different foldable acrylic intraocular lenses (IOLs) by measuring with photorefractor Plusoptix CR03 (Plusoptix GmbH, Nuernberg, Germany).
Methods: Fifty five pseudophakic eyes of 46 patients (mean age 65.25±10.63 years) were analyzed one month after uneventful phacoemulsification and IOL implantation surgery. Rayner Centerflex (C-Flex) (n=17), AcyrSof MA60BM (n=17), Sensar AR40e (n=21) IOLs were implanted. An objective, dynamic measurement technique with R mode of Plusoptix CR03 device was used to measure accommodation. Accommodation was measured at near distance (0.33m) and far distance (5m).
Results: Accommodation amplitudes (mean ± SD) measured with photorefractor at near distance in Rayner, AcyrSof and Sensar groups were 1.45±0.76 diopter (D), 2.82±1.88 D, 2.44±1.02 D, respectively. Accommodative response of AcyrSof and Sensar IOLs was greater than Rayner IOL significantly (p=0.027 and p=0.004, respectively). At far distance, measured accommodation amplitudes in Rayner, AcyrSof and Sensar groups were 1.34±0.54 D, 1.87±0.74 D and 1.74±1.70 D, respectively. There were no significant difference between the groups (p=0.109).
Conclusion: The 3-piece hydrophobic acrylic IOLs, AcrySof MA60BM and Sensar AR40e) had a significantly higher accommodative response than the 1-piece plate-haptic hydrophilic acrylic Rayner C-Flex IOL.
