摘　　要：目的：比较植入可调节、非球面和球面人工晶状体植入术后的视觉质量。方法选择2010年1月～2012年12月在济南市第二人民医院眼科白内障中心接受白内障超声乳化联合人工晶体植入术患者共180例（180眼），根据人工晶体植入类型分为3组：Telraflex 可调节人工晶体（A 组，60眼／60例），博士伦 Akreos AO 折叠式非球面人工晶体（B 组，60眼／60例），博士伦 Akreos Adapt 折叠式球面人工晶体（C 组，60眼／60例）。术后1、3、12个月进行随访，对术眼进行裸眼远视力、最佳矫正远视力（BCDVA）、最佳矫正远视力下的中间视力（DCIVA）、最佳矫正远视力下的近视力（DCNVA）、伪调节力和对比敏感度检查。结果患者裸眼远视力差异无统计学意义（P ＞0．05）。BCDVA 3组之间无明显差异（P ＞0．05）。DCIVA、DCNVA 及人工晶体眼伪调节力均表现为 A 组明显优于 B 组和 C 组（P ＜0．05）。在各百分比对比度下，3组患者的对比敏感度比较无显著性差异（P ＞0．05）。结论植入3种人工晶状体后，患者均可获得较好的远视力，相比于非球面及球面人工晶体，可调节人工晶状体均拥有更佳的远、中、近视力及较高的调节力。Objective To compare the performance of accommodative,spherical monofocal and aspheric monofocal intraocular lenses （IOLs）.Methods In this clinical control study,3 types of IOL were implanted in 180 eyes of 180 patients with age-related cataract who underwent phacoemulsification.Accommodative （Tetraflex）,aspheric monofocal （akreos advanced optics [AO]）（ZMA00）,and spherical monofocal （Akreos Adapt）IOLs were implanted.The uncorrected,best-corrected distance,contrast sensitivity,and distancecorrected intermediate and near visual acuity （UCDVA,BCDVA,CSVA,DCIVA,and DCNVA,respectively）,and amplitude of pseudoaccommodation were measured at 1,3,and 12 months after surgery.Results Differences in CSVA at all contrast degrees,UCDVA,and BCDVA among the three groups were not significant.Patients in the tetraflex group exhibited a better DCIVA and DCNVA and experienced more pseudoaccommodation compared to patients in the other two groups at 3 and 12 months after surgery （P 〈0.01 ）.Conclusion All the three types of IOLs allow greater distance visual acuity;However, tetraflex IOLs produced better DCIVA and DCNVA and more pseudoaccommodation.
