Comparison of visual function after multifocal and accommodative IOL implantation

To compare early visual function between patients undergoing phacoemulsification combined with multifocal and accommodative intraocular lens implantation.

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.

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).

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.
