We describe 2 cases of calcification of hydrogel intraocular lenses (IOLs) evaluated by optical coherence tomography. Dense or slight surface opacities of hydrogel IOLs were detected initially by slitlamp biomicroscopy in a 55-year-old woman and a 77-year-old woman. The opacities resulted in complaints of hazy vision after uneventful phacoemulsification and IOL implantation. Optical coherence tomography was used to further assess the opacities and showed calcification by high reflectivity on the anterior and posterior IOL surfaces in the first patient and on the anterior surface in the second patient. No abnormal reflectivity was seen on the surface of a hydrophobic acrylic IOL in the second patient's fellow eye. Optical coherence tomography may be useful to detect calcification of a hydrogel IOL.
我们描述了2例通过光学相干断层扫描评估的水凝胶人工晶状体（IOL）钙化病例。一名55岁女性和一名77岁女性最初通过裂隙灯生物显微镜检查发现水凝胶IOL有致密或轻微的表面混浊。在顺利进行超声乳化和IOL植入术后，这些混浊导致了视力模糊的主诉。光学相干断层扫描用于进一步评估混浊情况，结果显示，第一例患者的IOL前后表面出现高反射性钙化，第二例患者的IOL前表面出现钙化。在第二例患者的对侧眼中，疏水性丙烯酸IOL表面未观察到异常反射。光学相干断层扫描可能有助于检测水凝胶IOL的钙化情况。
