We report the case of a 76-year-old Chinese man who had uneventful cataract phacoemulsification and hydrophilic acrylic intraocular lens (IOL) implantation 6 years previously. He presented with decreased vision; a homogeneous milky substance was found between the posterior chamber IOL and the posterior capsule without IOL displacement or a change in the refractive status. The milky substance was aspirated from the capsular bag. Biochemical analysis showed the concentrations of proteins and Ca(++) in the milky liquid were higher than those in the aqueous humor. Protein identification by mass spectrometry indicated that the milky liquid contained a high concentration of alpha-crystallin and beta-crystallin.
我们报告了一例76岁中国男性患者的病例，该患者6年前接受了白内障超声乳化吸除术及亲水性丙烯酸人工晶状体（IOL）植入术，手术过程顺利。他出现了视力下降；在后房型IOL与后囊膜之间发现一种均匀的乳状物质，IOL未移位，屈光状态也未改变。从囊袋中吸出了该乳状物质。生化分析显示，乳状液中蛋白质和Ca(++)的浓度高于房水。通过质谱进行的蛋白质鉴定表明，乳状液中含有高浓度的α-晶状体蛋白和β-晶状体蛋白。
