目的初步观察植入 ReSTOR 多焦点人工晶状体眼的视功能,以评价 ReSTOR 多焦点人工晶状体植入的有效性及安全性。方法选择行白内障超声乳化吸除联合 ReSTOR 多焦点人工晶状体植入术的患者共21例(30只眼),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个月、6个月。结果植入 ReSTOR 人工晶状体患者术后3个月的术眼裸眼远近视力分别为0.8±0.25和0.86±0.2,术前与术后3个月的角膜散光度数比较差异无显著意义(P>0.05),对比敏感度降低,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%(18/21)。结论ReSTOR 多焦点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。
Objective To observe the visual function of ReSTOR multifocal intraocular lens (IOL) implantation to evaluate the effectiveness and safety of ReSTOR multifocal intraocular lens implantation. Methods A total of 21 patients (30 eyes) undergoing cataract with phacoemulsification combined with ReSTOR multifocal intraocular lens implantation were selected. The distance, near vision, corneal astigmatism, contrast sensitivity, complications, questionnaire Type investigation rate, poor visual acuity and satisfaction. The follow-up time was 3 months and 6 months after operation. Results There was no significant difference in corneal astigmatism between preoperative and postoperative 3 months after implantation of ReSTOR intraocular lens at 3 months postoperation (0.8 ± 0.25 and 0.86 ± 0.2 respectively) (P> 0.05) , The contrast sensitivity decreased, the spatial frequency bands were in the normal range, while the high spatial frequency bands were decreased in some cases, the mirror removal rate was 86% (18/21). Conclusion The ReSTOR multifocal intraocular lens (IOL) provides good near and far vision to the patient, with 86% of the patients taking off the glasses.
