方法：行超声乳化白内障吸除术的33例白内障患者，植入多焦点人工晶状体(试验组)19例25眼，植入单焦点人工晶状体(对照组)14例20眼。观察患者的术后远，中，近视力、立体视觉、不同距离下脱镜率。

结果：裸眼近视力≥0.5者，试验组为17眼，占68%(17/25)，对照组为6眼，占30%(6/20)，两组比较差异有统计学意义(P<0.05)； 裸眼远视力≥0.5者，试验组为23眼，占92%(23/25)，对照组为20眼，占100%(20/20)，两组比较差异均无统计学意义(P>0.05)。中间视力：40cm：试验组得分为54.64±10.80，对照组得分为47.05±6.39，两组比较差异有统计学意义(P<0.05)； 63cm：试验组得分为50.36±10.32，对照组得分为46.50±8.32，两组比较差异无统计学意义(P>0.05)； 100cm：试验组得分为43.44±8.08，对照组得分为42.05±6.63，两组比较差异无统计学意义(P>0.05)。立体视觉：试验组6例双眼手术，6例立体视锐度均≤60″； 对照组6例双眼手术，1例立体视锐度≤60″，两组比较差异有统计学意义(P<0.05)。视近如读书、看报时的戴镜率：试验组19例中有6例需要眼镜，对照组14例中有11例需要眼镜，两组比较差异有统计学意义(P<0.05)。

结论：多焦点人工晶状体Array在术后很长时间内使患者拥有良好的全程视力，为双眼手术者提供良好的立体视觉，减少术后患者对眼镜的依赖，提高患者的生活质量。

METHODS: Of 33 cases with phacoemulsification cataract operation, 19 cases(25 eyes)underwent implantation of multifocal intraocular lens(experimental group), 14 cases(20 eyes)implanted monofocal intraocular lens(control group). Postoperative far visual acuity, intermidiate visual acuity, near visual acuity, stereo vision, off glass rate under different distances was observed.

RESULTS: The near uncorrected visual acuity ≥0.5 in experimental group were 17 eyes(68%, 17/25), and that in control group were 6 eyes(30%, 6/20), there was significant difference between two groups(P<0.05). The far uncorrected visual acuity ≥0.5 in experimental group were 23 eyes(92%, 23/25), and that in control group were 20 eyes(100%, 20/20), there was significant difference between two groups(P>0.05). Intermediate visual acuity: 40cm: scores of experimental group were 54.64±10.80, scores of control group were 47.05±6.39, there was significant difference between two groups(P<0.05). 63cm: scores of experimental group were 50.36±10.32, scores of control group were 46.50±8.32, there was no significant differences between two groups(P>0.05). 100cm: scores were 43.44±8.08 and 42.05±6.63 in experimental group and control group, with no significant difference(P>0.05). Stereo vision: 6 cases of experimental group underwent bilateral operation, stereo acuity of 6 cases was ≤60″, 6 cases of control group underwent bilateral operation, 1 case stereoacuity was ≤60″, there was significant difference between two groups(P<0.05). Wear glasses rate when reading newspaper: 6 cases of the 19 cases in experimental group need glasses, 11 cases of the 14 cases in control group need glasses, there was significant difference between two groups(P<0.05).

CONCLUSION: Array multifocal intraocular lens offered good vision in postoperation, provided good stereo vision for operators, reduced the rely on glasses postoperation, improved the quality of life for patients.
