Visual quality of multifocal, accommodative and monofocal intraocular lens: a comparative study of 139 eyes
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
