方法：选取我院单纯性老年性白内障患者68例84眼，术前常规检查，以IOL Master确定人工晶状体度数，行白内障超声乳化术后联合植入Tecnis AMO00衍射型非球面多焦点人工晶状体。术后3mo随访，记录患者术后视力，以综合验光仪检查患者术后屈光状态并记录。

结果：近视36眼，远视48眼，球镜和柱镜度数均在-0.50～+0.50D之间，无明显屈光不正。术后裸眼远视力≥0.8者64眼(76%)，最佳矫正远视力≥0.8者77眼(92%)，裸眼近视力≥0.8者58眼(69%)，最佳矫正近视力≥0.8者74眼(88%)，中间距离视力≥0.8者58眼(69%)。

结论：衍射型非球面多焦人工晶状体能提供良好的全程视力，在IOL Master指导下更能精确选择度数，患者术后无明显屈光不正，视觉满意度高。

METHODS: Totally 68 patients(84 eyes)with age-related cataract were selected. Routine preoperative examinations were completed, and IOLs were determined under the guidance of IOL master. All the patients underwent phacoemulsification of cataract and multifocal IOL(Tecnis AMO00)implantation. 3 months later, postoperative visual acuity and the refraction(according to the integrated refractometer)of patients were observed.

RESULTS: The refraction types of these 84 eyes included 36 myopia and 48 hyperopia, with spherical and cylindrical diopter between -0.5D to +0.5D. No significant refractive error was detected. There were 64 eyes(76%)with postoperative uncorrected distance visual acuity ≥0.8, 77 eyes(92%)with best-corrected distance visual acuity ≥0.8, 58 eyes(69%)with uncorrected near visual acuity ≥0.8, 74 eyes(88%)with best-corrected near visual acuity ≥0.8, 58 eyes(69%)with intermediate visual acuity ≥0.8.

CONCLUSION: Diffractive aspheric multifocal IOL provides a high level of full vision, and will be more accurately selected under the guidance of IOL master. No significant refractive error was detected after surgery, and patients were much satisfied.
