目的:初步观察评估植入ReSTOR衍射型多焦点人工晶状体眼的视功能,以评价ReSTOR衍射型多焦点人工晶状体植入的有效性及安全性。方法:选择行超声乳化联合ReSTOR衍射型多焦点人工晶状体植入术的患者共41例60眼,观察患者术后远、近视力,角膜散光度数,对比敏感度,手术并发症,问卷式调查脱镜率、视觉不良症状和满意度。随访时间为术后3～6mo。结果:植入ReSTOR人工晶状体患者术后3mo术眼裸眼远近视力分别为0.80±0.25,0.86±0.20,术前与术后3mo角膜散光度数比较差异无统计学意义,对比敏感度在低、中空间频率段均位于正常范围内,高空间频率段则有部分病例有所下降。脱镜率为86%(33/41)。结论:ReSTOR衍射型多焦人工晶状体可为患者提供良好的远近视力,86%的患者可摘掉眼镜。

AIM:To evaluate the effectiveness and safety of implantation of ReSTOR multifocal intraocular lens(IOL).·METHODS:The study included 41 cases (60 eyes)of patients with cataract who received phacoemulsification with ReSTOR multifocal IOL implantation.Visual acuity,corneal astigmatism,contrast sensitivity,operative complications,spectacles independence,patient satisfaction and untoward visual symptoms were observed.The follow-up period was 3 to 6 months.·RESULTS:At 3 months after implantation,the average uncorrected distant visual acuity was 0.80±0.25 while the average near visual acuity was 0.86±0.20.There was no statistically significant difference between the preoperative corneal astigmatism and corneal astigmatism at 3 months after the operation.Contrast sensitivity in low and middle space frequency were all in the normal range,slightly declined in 2 eyes.The rate of off-glasses was 86% (33 cases).·CONCLUSION:ReSTOR diffractive multifocal IOL can offer a better near and far eyesight.And 86% of the patients can take off their glasses.
