[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.
