Objective      To assess the visual outcomes of the 3 types of intraocular lens

multifocal intraocular lens (MIOL ZMA00)

accommodating intraocular lens (AIOL

FLEX) and monofocal/single focus intraocular lens (SIOL

AKROS)

in the treatment of phacoemulsification for the patients with age-related cataract.       Methods      A randomized concurrent control trial was carried out in 95 patients (139 eyes) with age-related cataract who receiving phacoemulsification and implantation of artificial intraocular lens in our department during September 2010 to April 2011. Forty-three eyes of 30 patients underwent phacoemulsification and implantation of ZMA00

and another 33 age- and sex-matched patients (49 eyes) and 32 patients (47 eyes) had the same surgery but implantated with FLEX and AKROS respectively. All patients were assessed for visual acuity

accommodation amplitude and contrast sensitivity visual acuity in 1 d

1 and 3 months after operation.       Results      During the follow-up time

the patients in the ZMA00 and FLEX groups had better vision acuity than the AKROS group in uncorrected distance vision acuity (UDVA)

but no significant difference was found (P0.05). And the patients in the ZMA00 and FLEX groups had better corrected intermediate vision acuity (CIVA) than the AKROS group (P0.05). The corrected near vision acuity (CNVA) in ZMA00 group was the largest

followed by FLEX group and AKROS group in turn (P0.05). Defocus method showed that the accommodative amplitude had the same trend with CNVA. In all contrast degrees

there was no significant difference of contrast sensitivity among the 3 groups (P0.05). There were 86.7% patients of the ZMA00 group

63.6% of the FLEX group

and 18.8% of the AKROS group achieving total spectacle independence.       Conclusion      Three kinds of artificial lens can get better distance vision

but multifocal and accommodative intraocular lens possesses far better

and the higher rate of spectacle independence. Aspheric multifocal intra-ocular lens have no loss in contrast sensitivity

and take greater advantages than accommodating intraocular lens in near vision

and pseudo-conditioning capability.
