方法：选择老年性白内障患者44例55眼，行白内障超声乳化手术并按患者意愿植入传统单焦点人工晶状体或多焦点人工晶状体。多焦点人工晶状体组(multifocal intraocular lens， MIOL)：植入Acrysof IQReSTORE+3D，21例27眼； 传统单焦点人工晶状体组(monofocal intraocular lens， MoIOL)：植入Abbott Sensar，23例28眼，所有患者均无影响术后视力的其他眼部疾病。观察两组患者术后3mo裸眼远视力、裸眼近视力、最佳矫正远视力、最佳矫正近视力、眼压、脱镜率、视觉症状、患者自觉舒适满意评价。

结果：MIOL裸眼近视力、脱镜率、视觉症状、患者自觉舒适满意评价均优于MoIOL(P<0.05)，眼压变化两组比较无明显差异(P<0.05)。

结论：白内障超声乳化手术并植入多焦点人工晶状体后，与传统单焦点人工晶状体相比，前者能提供令人满意地远、中、近视力，患者能获得较高的视觉质量，满意程度高，双眼植入者效果更理想。

METHODS: Forty-four patients of senile cataract(55 eyes)were selected to perform phacoemulsification, and monofocal or multifocal IOL was implanted according to the willingness of the patients. For multifocal IOL group(“MIOL”), Acrysof IQReSTORE+3D were implanted for 21 patients 27 eyes in total; for monofocal IOL group(“MoIOL”), Abbott Sensar were implanted for 23 patients 28 eyes in total. All patients suffered no other oculopathy which may affect postoperative visual acuity. Three months after operation, observation was made on two groups of patients with respect to uncorrected distance visual acuity, uncorrected near visual acuity, best-corrected distance visual acuity, best-corrected near visual acuity, intraocular spectacles abandon rate, visual symptom, self assessment of comforts and satisfaction by patients.

RESULTS: In terms of uncorrected near visual acuity, spectacles abandon rate, visual symptom, self assessment of comforts and satisfaction by patients, MIOL group made a better assessment than MoIOL group. No evident difference related to intraocular variation between MIOL and MoIOL was discovered.

CONCLUSION: Comparing with implant of traditional monofocal IOL, performing phacoemulsification with implant of aspheric diffraction-type multifocal IOL could help patients achieve satisfactory distant, medium and near vision. With better vision quality, patients have higher satisfactory rate of operational effect. The postoperative results were even more obvious with patients who have received operation for two eyes.
