[The observation of visual quality after the implantation of apodized diffractive multifocal intraocular lens].

OBJECTIVE: To obverse visual acuity, visual symptom and the rate of spectacle independence after implantation of a multifocal intraocular lens (MIOL) in patients with age related cataract. METHODS: Sixty patients (68 eyes) with age-related cataract were enrolled in two groups. ReSTOR SA60D3 MIOL and Natural SN60AT monofocal intraocular lens were specially implanted after phacoemulsification. Uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), uncorrected near visual acuity (UCNVA), best-corrected near visual acuity (BCNVA), distance-corrected near vision acuity (DCNVA), visual symptom and the rate of spectacle independence were observed. RESULTS: UCDVA and BCDVA in multifocal group were not statistically different from those in monofocal group (P > 0.05). UCNVA and DCNVA were statistically better in multifocal group than in monofocal group (P < 0.05). The multifocal group has higher rate of spectacle independence than the monofocal group (73.3% versus 13.3%) (P < 0.05) when reading. The visual symptom such as glare and halo were more serious in multifocal group than in monofocal group (P < 0.05). CONCLUSIONS: Acrysof ReSTOR apodized diffractive multifocal intraocular lens may provide an excellent distance and near visual acuity, and decrease the dependence of spectacle.
