Comparison of Visual Function after Multifocal and Accommodative IOL Implantation

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 at1 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.
