AIM:To evaluate clinical effects of the apodized diffractive multifocal intraocular lens(MIOL)implantation.

METHODS: Seventy-two patients(72 eyes)with age-related cataract were divided into two groups by randomized controlled clinical trials, 32 eyes of 32 cases received the apodized diffractive MIOL, 40 eyes of 40 cases received monofocal intraocular lens(MoIOL). Three months after surgery, uncorrected distance visual acuity(UCDVA), intermediate visual acuity(IVA), near vision, correct near and far vision were observed. Visual function and quality of life questionnaire was measured.

RESULTS:Three months after surgery, the uncorrected near visual acuity(UCNVA)and IVA(40, 60, 80cm)in MIOL group were significantly higher than that in MoIOL group(P<0.05). The UCDVA, best corrected distant visual acuity(BCDVA), best corrected near visual acuity(BCNVA)and distant corrected visual acuity(DCNVA)had no statistically significant difference between two groups(P>0.05). Contrast sensitivity values had no statistically significant difference between two groups at 3mo postoperatively(P>0.05). The spectacle independence in MIOL group was significantly higher than that in MoIOL group(P<0.05)and near vision satisfaction in MIOL group was higher than that in MoIOL group(P<0.05). Compared with those adverse visual symptoms and distant vision satisfaction, there were no statistically significant difference between two groups(P>0.05).

CONCLUSION: The apodized diffractive MIOL can provide excellent full range of vision and visual quality, effectively decrease the dependence of glasses and improve the life quality after sugery.
