个性化人工晶状体选择方案治疗年龄相关性白内障的临床研究

Clinical study on individualized plans of intraocular lens for age-related cataract

目的:为使年龄相关性白内障患者术后得到更好的视觉质量及术后满意度,我们提出个性化人工晶状体选择方案。方法:将2009-07/2015-04于我院眼科进行手术的年龄相关性白内障患者选取为研究对象,按患者最终植入的IOL类型分为4组:球面组、非球面组、散光组及多焦组。术后3mo时对患者主观视觉质量、满意度、视力、总和散光、对比敏感度等进行检查。结果:共入选174例254眼患者。术后平均满意度得分为8.17±1.02分,其中散光组与多焦组的满意度较其他两组高(P<0.05)。四组患者术后视力均较术前显著提高(P<0.05),其中多焦组的术后裸眼近视力显著高于其他3组(P<0.05)。散光组在白天3、6、12、18c/d空间频率下及夜间18c/d空间频率下的对比敏感度较其他三组好(P<0.05)。结论:个性化人工晶状体选择方案针对患者眼部情况及对手术后视力的不同需求,选择植入患者合适的人工晶状体,对患者术后视力、对比敏感度及满意度的提升有重大意义。

AIM：To make better postoperative visual quality and satisfaction,we propose individualized plans of intraocular lens for age-related cataract patients.·METHODS：Patients with cataract who hospitalized in our department from July 2009 to April 2015 were recruited as objects.According to patients＇ implanted IOL types we divided them into 4 groups：spherical group,non-spherical group,astigmatism group and multi- focal group.Three months after the surgery,the patients were examined by subjective visual quality,satisfaction degree,visual acuity,total astigmatism and contrast sensitivity.·RESULTS：A total of 174 patients（254 eyes） were enrolled.The average satisfaction of the patients was 8.17±1.02 scores,and the satisfaction of the astigmatism group and the multi-focal group were higher than the other 2groups（P0.05）.The postoperative visual acuity of the 4groups were statistically significant higher（P0.05） than the preoperative,in which the postoperative near visual acuity of multi-focal group was significantly higher than the other 3 groups（P0.05）.The day contrast sensitivity under 3,6,12 and 18c/d spatial frequency and the night contrast sensitivity under 18c/d spatial frequency of the astigmatism group was better than the other 3 groups（P0.05）.·CONCLUSION：Individualized plans of intraocular lens are aimed to recommend appropriate types of IOL according to the different ocular conditions and postoperative needs of patients.It has great significance to improve the patients＇ visual acuity,contrast sensitivity and satisfaction.
