目的:评价SN6AD1多焦点人工晶状体(MIOL)植入术后的临床效果。方法:选择我院2010-01/11白内障患者44例65眼,超声乳化白内障吸除术后植入SN6AD1MIOL,术后随访3～6mo,观察裸眼及矫正远、中、近视力,最佳远视力矫正下的中、近视力,角膜散光,离焦曲线,脱镜率和满意度。结果:术后3mo,患者远、近视力理想,中距离视力亦较为满意;术前术后平均角膜散光差异无显著性(P>0.05);离焦曲线呈双峰型,第一个峰位位于0D,第二个峰位为一高平台,位于-2.00～-2.50D;44例手术患者中39例(89%)脱镜;脱镜患者可从事日常远、中、近距离工作。结论:SN6AD1MIOL可为患者提供良好的全程视力,提高脱镜率。

AIM:To evaluate the clinical efficacy after the implantation of SN6AD1 multifocal intraocular lens(MIOL). METHODS:After the phacoemulsification, SN6AD1 MIOL was inserted into 65 eyes of 44 patients. The mean follow-up duration was 3 to 6 months. The visual acuity, corneal astigmatism, defocus testing, rate of off-glasses and patient satisfaction were observed. RESULTS:At 3 months after the implantation, the average distant, intermedia and near visual acuity were satisfying. There was no statistically significant difference between the preoperative corneal astigmatism and corneal astigmatism at 3 months after the operation(P>0.05). The defocus curve showed double-peak shape,of which one peak was at the point of 0D and the other peak was on the plateau of -2.00--2.50D. Thirty-nine (89%) patients took off their glasses, who could engage in various distance work. CONCLUSION:SN6AD1 MIOL can offer a better whole range of vision and increase the rate of off-glasses.
