目的 :比较多焦点人工晶状体 (MIOL)与单焦点人工晶状体 (SIOL)植入术后早期患者的视觉质量改变 ,评价多焦点人工晶状体植入的有效性及安全性。方法 :从我院住院的老年性白内障患者中选择病例 4 4例 (6 0只眼 ) ,随机分为两组 ,每组 30只眼 ,行超声乳化白内障吸出术 ,MIOL组植入AMOArraySA4 0N ,SIOL组植入AllerganSI4 0NB。术后 1天查远、近视力 ,3个月对患者进行远、近视力、对比敏感度 (CS)、色觉、视野及拟调节力等视功能的检查 ,问卷调查视物情况及视觉症状。结果 :MIOL眼具有与SIOL眼一样良好的裸眼远视力 ,两组分别为 1 0 0± 0 2 7、0 89± 0 2 3(P >0 0 5 ) ,裸眼近视力MIOL眼明显优于SIOL眼 ,分别为 0 86± 0 2 7、0 4 5± 0 14 (P <0 0 5 ) ;两组患者的CS在低、中空间频段均位于正常范围内 ,高空间频段均有部分病例稍下降 ,异常率两组的差异无显著性意义 (P >0 0 5 ) ;两组患者的色觉无异常 ;自动视野计检查发现MIOL组 1例 (1只眼 )视野缺损 ,其余患者视野正常 ;MIOL眼焦深大于SIOL眼 ,分别为 +1 0D～ - 3 5D、+1 0D～ - 1 0D ;多数患者对手术效果满意 ,MIOL组近距离作业满意度高于SIOL组 (85 71%、34 78% ,P <0 0 5 ) ;近用镜脱镜率MIOL组 5 7 14 % ,SIOL组无人能脱镜 ;两组患?
OBJECTIVE: To evaluate the visual quality of multifocal intraocular lens (IOL) and multifocal intraocular lens (IOL) implantation in early stage after MIOL and single focus intraocular lens implantation. Methods: Forty-four cases (60 eyes) of senile cataract patients hospitalized in our hospital were selected and randomly divided into two groups (n = 30). Phacoemulsification cataract extraction was performed. MIOA group was implanted with AMOArraySA40N, The SIOL group was implanted with Allergan SI4 0NB. One day after operation, the patients were examined for distance, near visual acuity, visual acuity of far vision, near vision, contrast sensitivity (CS), color vision, vision and hypnagogic power of 3 months, and the visual acuity and visual symptoms were surveyed. Results: The MIOL eyes had the same excellent visual acuity as the SIOL eyes. The two groups were respectively 100 ± 0. 27, 89 ± 0 2 3 (P> 0.05) Eyes, respectively, 0 86 ± 0 2 7,0 4 5 ± 0 14 (P 0 05); CS in both groups in the low and medium spatial frequency bands are located in the normal range, the high spatial frequency band has some cases slightly There was no significant difference between the two groups (P> 0.05). There was no abnormal color vision in the two groups. One case (1 eye) in MIOL group was found to have visual field defect and the rest had normal vision. The MIOL eye focus was larger than that of the SIOL eye, which were respectively +1 0D ~ -3 5D and + 1 0D ~ -1 0D. Satisfactory results were obtained in most patients, and the MIOL group was more satisfied with the SIOL group (85 71%, 34 78%, P <0 05). In the MIOL group, 5 7 14%
