摘　　要：目的比较植入黄色人工晶状体(IOL)及非球面变色IOL的白内障患儿术后对比度视力和色觉的差异。设计回顾性病例系列。研究对象白内障接受超声乳化联合IOL植入手术治疗的患儿43例(56眼)。方法患儿按照术中植入的IOL不同分为两组:黄色IOL组(26眼)和非球面变色IOL组(30眼),所有复查患眼均在术后3个月以上,进行视力、眼压、裂隙灯检查、眼底、对比度视力和色棋检查。主要指标视力、对比度视力、色棋错误评分。结果两组患儿的术后裸眼视力和矫正远视力无显著差异。在40 lux光照下,5%对比度下非球面变色IOL组的视力(0.21±0.14)要优于黄色IOL组(0.39±0.11)(P=0.001)。明视下(户外日照和室内1000 lux光照),两组间的FM100测试的总错误评分无显著差异,黄昏视下(40 lux)黄色IOL组的辨色力错误总评分(48.51±16.73)明显高于非球面变色IOL组(31.25±11.39)(P=0.003)。结论黄色IOL和非球面变色IOL在强光下对比度视力无明显差别,而非球面变色IOL在弱光下能够提供更好的对比度视力和更强的色彩辨别能力。Objective To compare the differences of contrast vision and color vision after implanting yellow intraocular lens（IOL）with aspheric photochromic IOL in cataract surgery in children. Design Retrospective case series. Participants 43 cases（56 eyes） with cataract who were treated by phacoemulsification and IOL implantation. Methods According to the different IOL, patients were divided into two groups： 26 eyes in the yellow IOL group, 30 eyes in the aspheric photochromic IOL group. All eyes were reviewed after 3months postoperatively. Visual acuity, intraocular pressure（IOP）, slit lamp examination, fundus, contrast vision and color vision were examed and compared in the two groups. Main Outcome Measures visual acuity, contrast vision and color vision. Results The postoperative uncorrected visual acuity and corrected visual acuity had no significant difference between two groups. The aspheric photochromic IOL group had the better contrast vision（0.21±0.14） than yellow IOL group（0.39±0.11） in 40 lux, 5% contrast conditions（P=0.001）. The total error scores of FM 100 test were not significantly different between the two groups in the photopic conditions（outdoor sunshine and indoor 1000 lux）, but the total error scores of the yellow IOL group（48.51±16.73） was significantly higher than that of the aspheric photochromic IOL group（31.25±11.39） in the mesopic conditions（40 lux）（P=0.003）. Conclusion There were no significant difference of contrast vision between the yellow IOL and the aspheric photochromic IOL under the photopic conditions, and the aspheric photochromic IOL can provide the better contrast vision and color vision under the mesopic conditions.
