PURPOSE: To compare early visual function between patients undergoing phacoemulsification combined with multifocal and accommodative intraocular lens implantation. METHODS: A total of 112 patients with age-related cataract undergoing phacoemulsification in our hospital were recruited for this study and randomly assigned into multifocal (56 eyes; ZAM00 group) and accommodative (56 eyes; FLEX group) intraocular lens groups. Visual acuity and contrast sensitivity were statistically compared between the two groups. RESULTS: No significant difference was found in uncorrected distant visual acuity between the ZMA00 and FLEX groups at 1 week, or 1, 3, and 6 months after operation (all P > 0.05). At postoperative 6 months, no statistical significance was noted in distant and intermediate best-corrected visual acuity or in contrast sensitivity between the two groups (all P > 0.05). Patients in the ZMA00 group were superior to their counterparts in the FLEX group regarding near best corrected visual acuity, reading speed, and spectacle independence (all P < 0.05). CONCLUSION:ZMA00 and FLEX IOL implantation can provide excellent distant and intermediate visual acuity for patients with age-related cataract. ZMA00 IOL is superior to FLEX in terms of near visual acuity.
