方法：选取2009-01-01/2011-12-01在我院进行的白内障超声乳化联合IOL植入手术的患者160例190眼为研究对象，对患者的临床基本资料以及手术治疗情况进行总结分析，探讨其发生角膜水肿的原因，并提出针对性的预防及处理方案。

结果：患者190眼中，共有67眼出现术后角膜水肿，其中年龄相关性白内障术后发生的角膜水肿为25眼(13.2%)； Ⅰ～Ⅱ级核发生的角膜水肿为6眼(3.2%)； Ⅲ～Ⅴ级核发生的角膜水肿为56眼(29.5%)。

结论：对于白内障超声乳化联合IOL植入术后发生角膜水肿的原因，主要和手术医生的操作熟练程度及手术技巧有关，要采取积极的预防措施，在手术中严格操作，注意细节，从根本上控制角膜水肿的发生原因，以减少患者的痛苦，提高手术成功率。

METHODS: Totally 160 patients 190 eyes who underwent Phaco combined IOL implantation during 2009 to 2011 were selected. The basic information and treatment of the patients were analyzed, the cause of cornea edema after surgery was investigated and the precautions and measure were proposed.

RESULTS: Of the 190 eyes, 67 eyes appeared cornea edema after Phaco combined IOL implantation, including 25 eyes from age-related cataract patients. The incidence rate was 13.2%. 6 eyes appeared cornea edema from I and II degree nuclei patients. The incidence rate was 3.2%(6/75). 56 eyes appear cornea edema from III to V degree nuclei patients. The incidence rate was 29.5%(56/115). The records had statistical differences(P<0.05).

CONCLUSION: The reason of cornea edema after Phaco combined IOL implantation has relationship with the operation skills of the surgeons and the careful operation during the surgery is the basic of the precautions which reduce the pain of the patients and raise the success ratio of the surgery.
