摘　　要：人工晶状植入术是目前矫正无晶状体眼屈光的最有效的方法，它在解剖上和光学上取代了眼睛原来的晶状体，其术后可迅速恢复视力。在上海某医院，一名患者在眼部植入人工晶体五年后，手术效果出现非正常下降。为了排查原因．将人工晶体取出进行剖析，发现晶体一侧表面出现了混浊。该表面的混浊是植入效果变差的原因，但晶体表面变浑的原因不明。该人工晶体材质为聚甲基丙烯酸甲酯，简称PMMA。植入人体后，表面沉积的物质可能为有机质，也可能为无机的生物钙化物质。为了更全面的剖析其成分，我们联用岛津能量色散X射线荧光（EDX）和傅里叶变换红外光谱仪（FTIR）对其表面混浊部位进行了分析，研究其混浊部分的来源，对延长人工晶体植入术的疗效有积极意义。Artificial crystal implantationis the most effective method for correction of lensless refraction It replaced the original lens of the eyes in anatomy and optics.It can quickly recover visionafter surgery.A patient＇s surgical effectdecreased after operation for five year in a Shanghai hospital. Then the artificialcrystal was taken out for analysis in order to find the reason. Moreover, we find that the lens was turbidity. The material of the artificial crystal is polymethylmethacrylate, which is PMMA. It maybe organic and inorganic that deposited on the surface afterbe implanted into the eyes. The study determination of the contamination on artificial crystal by Shimadzu EDX and FTIR. it has a positive significance for prolonged the intraocular of lens implantation
