摘　　要：目的: 研究三种非球面丙烯酸酯人工晶状体(intraocularlens,IOL)植入术后患者在最佳矫正视力及暗视下(3cd/m2)对比敏感度(contrast sensitivity,CS)的变化,评价白内障超声乳化联合单焦点非球面丙烯酸酯IOL植入术后患者的视觉质量。方法: 选取符合条件的年龄相关性白内障患者77例90眼,2011-12/2012-11于我院行白内障超声乳化吸除联合IOL植入术,术前将患者随机分成三组,1组(25例30眼)植入疏水性染黄色丙烯酸酯IOL(HOYA),2组(28例30眼)植入亲水性丙烯酸酯IOL(Rayner)及3组(24例30眼)植入亲水性丙烯酸酯表面肝素处理IOL(XO)。所有患者于术后1,3mo均行最佳矫正视力(标准对数视力表)检查及暗视无眩光状态下的CS检查,所得结果进行统计学分析。结果: 患者术后1,3mo时,各组之间最佳矫正视力无明显统计学差异(P>0.05);患者1,3mo暗视无眩光状态下CS结果(标准化后的CS值:lgCS),三组患者之间CS值并无统计学差异(各组之间P>0.05),但HOYA组患者CS结果略下降。结论: 三组患者之间,术后1,3mo时最佳矫正视力及对暗视无眩光状态下CS结果无明显差异(P>0.05)。由于蓝光滤过型IOL对视网膜的潜在保护作用,因此植入染黄色滤过蓝光的IOL是可取的,特别是对儿童及青年白内障患者是必要的。·AIM：To evaluate best corrected visual acuity （BCVA） and contrast sensitivity （CS） under mesopic condition with no glare in patients following implantation of three different kinds of aspheric acrylic monofocal intraocular lens （ IOLs）. ~ METHODS： Seventy- seven cases （90 eyes） of age- related cataract patients were selected, who were undergone phacoemulsification and intraocular lens （IOL） implantation in our hospital during December 2011 to November 2012. Preoperatively, the patients were randomly divided into three groups： 30 eyes （25 cases） were implanted with hydrophobic yellow-tinted acrylic （HOYA） IOLs in group 1; 30 eyes （28 cases） with hydrophilic acrylic IOLs （Rayner） in group 2; 30 eyes （24 cases） with hydrophilic acrylic surface heparin processing IOLs （XO） in group 3. All eyes were evaluated at 1 month and 3 months postoperatively. The BCVA and CS under mesopic condition without glare were measured and underwent statistical analysis.·RESULTS： There was neither statistically significant difference in the BCVA （P 〉 0. 05）, nor statistically significant difference in CS results （after standardization of contrast sensitivity value： IgCS） （P〉0.05） between groups under mesopic condition, but the IgCS of the HOYA group decreased slightly.· CONCLUSION： There were not marked differences of BCVA and CS between groups of patients at the follow-up intervals of 1 month and 3 months under mesopic condition. The blue-filter type artificial lens may protect the retina, thus, it is advisable to implant yellow-tinted filter blue artificial lens, especially for patients who are children or young persons.
