目的观察Matrix Acrylic 400型人工晶状体,植入人眼后,在自然光下其是否有光致变色作用.方法 42例年龄相关性白内障患者分为三组,分别植入Matrix Acrylic 400型人工晶状体,Acrysof Natural SN60AT人工状晶体及Matrix Acrylic 401型人工晶状体.术后1 d、1周、1个月、3个月观察三组视力、logMAR视力及在室外日照及室内条件下人工晶状体的颜色变化.结果所有患者术后测定术眼裸眼远视力、最佳矫正远视力差异无统计学意义.三组患者在明视条件下三种对比度LogMAR视力差异无统计学意义,暗视条件下5%对比度时的logMAR视力黄色人工晶状体组低于另外两组,差异有统计学意义.照片拍摄显示在室内Matrix Acrylic 400型光致变色人工晶状体和Matrix Acrylic 401型人工晶状体呈无色透明,Acrysof Natural SN60AT人工晶状体呈黄色.在室外阳光下Matrix Acrylic 400型光致变色人工晶状体明显变为为黄色,Matrix Acrylic 401型人工晶状体仍无色透明,Acrysof Natural SN60AT人工晶状体呈黄色.结论 Matrix Acrylic 400型人工晶状体在人眼内可以在室外自然光条件下变为黄色,在室内黄色消退.在暗视5%对比度条件下LogMAR视力优于黄色人工晶体.

Objective To evaluate light accommodation effect of the intraocular photochromic blue light-filtering IOL (Matrix Acrylic 400 101) under the natural light. Methods Forty-two age related cataract patients (59 eyes) were divided into three groups in random. These three cataract groups were 'implanted Matrix Acrylic 400 IOLs, Acrysof Natural SN60AT IOLs and Matrix Acrylic 401 IOLs respectively. The visual acuity and logMAR vision of these cases were recorded at I day, 7 days, 1month, and 3 months afier operation, respectively. The photochromic changes of these IOLs were evaluated indoor and outdoor environment at the same time. Results There were no significant differences in the aspects of distance visual acuity, corrected distance visual acuity and logMAR vision of all patients in photopic condition. The logMAR vision of SN60AT IOLs group was lower than the other two groups in scotopic 5% contrast condition (P <0.05). The Matrix Acrylic 400 IOLs and the SN60AT IOLs were yellow, but the Matrix Acrylic 401 IOLs were transparent under the sunlight outdoor environment. The SN60AT IOLs were still yellow, but the Matrix Acrylic 400 IOLs and the Matrix Acrylic 401 IOLs was transparent at indoor environment. Conclusions Matrix Acrylic 400 IOL changes to yellow at outdoor and retums to transparent at indoor. Under scotopic condition of 5% contrast, the logMAR vision of the 400 IOL group is better than that of the blue light-filtering IOL group.
