角膜上皮基底膜营养不良与白内障手术

Epithelial basement membrane dystrophy and cataract surgery

摘要:

角膜上皮基底膜营养不良(EBMD)是一种较为常见的前部角膜营养不良，临床表现隐匿，易被漏诊，患者通常主诉轻度视觉模糊或异物感，或在夜间或早晨打开眼睑后立即出现偶发疼痛。典型的裂隙灯检查表现包括角膜表面不规则、无定形，可发现指纹样、地图样线状病灶、点状或气泡样病灶。该病对白内障术前生物测量和人工晶状体度数计算具有重要影响，可导致测量不准及术后屈光意外，需引起白内障手术医生的重视。本文综述了近年来关于EBMD对白内障手术影响的相关研究和会议报告，为屈光性白内障手术医生提供参考，以提高手术前后的正确诊断和检出率，从而为患者提供最佳治疗方案。

Abstract:

Epithelial basement membrane dystrophy(EBMD)is a common anterior corneal dystrophy with hidden and easily missed clinical manifestations. Patients usually complain of mild blurred vision or foreign body sensation, or occasional pain at night or immediately after opening the eyelid in the morning. Slit-lamp examination revealed irregular, amorphous corneal surfaces, fingerprint-like linear lesions, and punctate or bubble-like lesions. EBMD has a significant impact on preoperative biometrics and intraocular lens power calculation, which can lead to inaccurate measurement and postoperative refractive accident, and cataract surgeons must be aware of this. This article reviews recent research and conference reports on the impact of EBMD on cataract surgery, as a reference for refractive cataract surgeons, thus improving the preoperative diagnosis and detection rate, so as to provide the optimal treatment plan for patients.
