AIM:To evaluate the clinical effect of the Acrysof ReSTOR multifocal intraocular lens(IOL)by comparison of pseudoaccommodation and visual quality between Acrysof ReSTOR multifocal IOL and Acrysof SN60AT monofocal lens implantation at 3 years follow-up.

METHODS: A total of 68 patients 80 eyes with age-related cataract underwent phacoemulsification and IOL implantation were divided into two groups. One group of 32 patients 40 eyes received Acrysof ReSTOR multifocal IOL(group A), the other 36 patients 40 eyes received Acrysof SN60AT monofocal lens(group B). Pseudoaccommodation, the postoperative uncorrected distance and near visual acuity, the best-corrected distance and near visual acuity, distance-corrected near visual acuity and contrast sensitivity were statistically analyzed. Also, visual quality and satisfactory after the operation were evaluated by questionnaires.

RESULTS: All patients had similar uncorrected distance visual acuity, best-corrected distance and near visual acuity postoperatively(P>0.05). The multifocal eyes was better than the monofocal eyes in uncorrected near visual acuity, distance-corrected near visual acuity, pseudoaccommodation and independence on spectacles(P<0.01), and nearly all subjects were satisfied with the results of their surgery.

CONCLUSION: The Acrysof ReSTOR multifocal IOL implantation can provide a high level of uncorrected and corrected distance vision, improve uncorrected and distance-corrected near vision and reduce spectacle dependency with a high level of patients' satisfaction.
