Abstract: Objective To compare the performance of accommodative, spherical monofocal and aspheric monofocal intraocular lenses (IOLs). Methods In this clinical control study, 3 types of IOL were implanted in 180 eyes of 180 patients with age-related cataract who underwent phacoemulsification. Accommodative (Tetraflex), aspheric monofocal (akreos advanced optics [AO]) (ZMA00), and spherical monofocal (Akreos Adapt) IOLs were implanted. The uncorrected, best-corrected distance, contrast sensitivity, and distancecorrected intermediate and near visual acuity (UCDVA, BCDVA, CSVA, DCIVA, and DCNVA, respectively), and amplitude of pseudoaccommodation were measured at 1, 3, and 12 months after surgery. Results Differences in CSVA at all contrast degrees, UCDVA, and BCDVA among the three groups were not significant. Patients in the tetraflex group exhibited a better DCIVA and DCNVA and experienced more pseudoaccommodation compared to patients in the other two groups at 3 and 12 months after surgery (P<0.01). Conclusion All the three types of IOLs allow greater distance visual acuity; However, tetraflex IOLs produced better DCIVA and DCNVA and more pseudoaccommodation.
