[Pay attention to the corneal epithelial cell dysfunction after cataract surgery].

Corneal epithelial dysfunction ( CED ) is the abnormality of the regeneration, conjunction, adhesion and immigration of the corneal epithelium cells without the decompensation of the corneal limbal cells. Due to the affection resulting from the systemic problems of patients and the management in the preoperative period, some of the patients at one to two weeks after cataract surgery will present the edema and fluorescein staining of the corneal epithelium. Without correct therapy, the defect of the epithelium, or even persisting ulceration of the cornea will occur. The key points of the management for CED are the early diagnosis and reasonable therapy. We suggest paying special attention to CED in the patients with metabolism diseases, abnormality of the tear film and long-term blepharitis.
