AIM:To investigate the visual quality after multifocal artificial lenses(MIOLs)implantation through coaxial micro-incision in age-related cataract patients.

METHODS:This was a retrospective non-random case control study. Forty-eight patients(60 eyes)with age-related cataract who underwent coaxial micro-incision phacoemulsification and implantation of AcrySof ReSTOR intraocular lens from February 2013 to August 2014 in the First Affiliated Hospital of Huzhou University were selected as trial group. Thirty-six general information matched senile cataract patients(50 eyes)who underwent coaxial micro-incision phacoemulsification and implantation of monofocal intraocular lens were served as controls. The postoperative uncorrected distance visual acuity and uncorrected near visual acuity, daily visual satisfaction were observed and compared.

RESULTS:Two groups were implanted with intraocular lens successfully. In trial group, at 3mo postoperatively uncorrected distance visual acuity was 0.75±0.25, uncorrected near visual acuity was 0.70±0.18. Patients' daily visual satisfaction was 96%. In control group, at 3mo postoperatively uncorrected distance visual acuity was 0.79±0.36, uncorrected near visual acuity was 0.31±0.11. Patients' daily visual satisfaction was 75%. There were statistically significant differences at 3mo postoperatively on uncorrected near visual acuity and daily visual satisfaction between the two groups(P<0.05), but was no statistically significant difference on postoperative uncorrected distance visual acuity(P>0.05).

CONCLUSION:The trial group(multifocal artificial lenses implantation)is superior to control group on uncorrected near visual acuity and daily visual satisfaction. Two groups have equal result on uncorrected distance visual acuity at 3mo postoperatively.
