双眼多焦点人工晶状体ReSTOR植入术后视功能观察

目的 通过比较植入单、多焦人工晶状体(IOL)术后双眼视功能情况,以了解国人植入多焦点IOL的有效性及安全性.方法 选择年龄相关性白内障患者43例,按患者意愿植入多焦点或单焦点IOL.单焦点人工晶状体(MoIOL)组:双眼植入AcrysofNatural25例50只眼.多焦点人工晶状体(MIOL)组:双眼植入AcrysofReSTOR 18例36只眼.观察两组组患者术后双眼裸眼远视力(UCDVA)、裸眼近视力(UCNVA)、最佳矫正远视力(BCDVA)、最佳矫正近视力(BCNVA)、远矫正下的近视力(DCNVA),中间距离视力(40、60、80cm),对比敏感度(CS),视觉症状.结果 MIOL组UCNVA、DCNVA、中间距离视力均优于单焦点人工晶状体MoIOL组,差异有统计学意义(P＜0.05).两组之间,CS无明显差异.MIOL组术后视觉症状较轻,脱镜率80%,患者满意度高.结论 双眼植入MIOL能提供更好的近、中距离视力,视觉症状轻,更好地提高白内障患者术后生活质量.

Visual function with bilateral implantation of AcrySofReSTOR multifocal intraocular lens

Objective To evaluate the effectiveness and security after implantation of multifocal intraocular lens in Chinese,by comparing the visual function of bilateral implantation of the new apodized diffractive AcrySof ReSTOR multifocal intraocular lens (MIOL) and Acrysof Natural, Monofocal intraocular lens (MoIOL) Methods Forty-three patients with age-related cataract were divided into two groups with random principia: bilateral Acrysof ResToR multifocal IOLs or the monofocal AcrySof Natural lols. The Acrysof ReSTOR group included 18 patients (36 eyes), and reference group-AcrysofNatural group (MoIOL) included 25 patients (50eyes). Measurements were taken after operation, including uncorrected distant vision acuity (UCDVA), uncorrected near vision acuity (UCNVA), best corrected distant vision acuity (BCDVA), best corrected near vision acuity (BCNVA), distant corrected near vision acuity (DCNVA), Intermediate Vision (40, 60,80 cm), contrast sensitivity (CS) and visual symptoms. Results UCNVA, DCNVA and Intermediate Vision (40, 60, 80cm)were significantly higher in the MIOL group (P＜0.05). No statistical difference was noted between 2 groups with the CS. The adverse symptoms of the MIOL group were slight. The dependence of glasses of the MIOL was 80%. The MIOL group provided better patient satisfaction. Conclusions Bilateral implantation in patients with the new apodized diffractive MIOL multifocal intraocular lens (IOL) appears a better outcome in near and intermediate vision, slight visual symptom, improve the quality of life after surgery.
