目得：目的：研究术后早期透明角膜切口（CCI）的结构，使用光学相干断层扫描（OCT）。单位：查尔斯王子眼科中心，爱德华七世医院，温莎，英国。方法：34例成人眼的34个CCI前瞻性检查，使用卡尔蔡司Visante前段OCT成像系统在1小时内顺利超声乳化白内障手术。使用4种宽度的不锈钢刀片（2.20 mm、2.50 mm、2.75 mm和3.20 mm）创建CCI。随后立即独立进行Seidel试验、逆Seidel试验和眼内压（IOP）测量。OCT图像在评价前随机化并设盲。结果：CCI平均长度为1.61 mm +/- 0.26（SD）（范围1.10 - 2.25 mm）。平均切口角度为40.7 ± 9.43度（范围24 - 56度）。CCI的5种结构特征的发生率如下：上皮开口（12%）、内皮开口（41%）、内皮错位（65%）、后弹力膜局部脱离（62%）和接合丧失（9%）。在二维图像中，内皮裂开导致伤口贴壁减少高达20%，接合丧失导致伤口贴壁减少高达25%。平均术后IOP为16.1 ± 9.02 mm Hg（范围3 - 46 mm Hg）。角膜后弹力膜局部脱离者眼压较低（P
PURPOSE: To investigate clear corneal incision (CCI) architecture in the immediate postoperative period using optical coherence tomography (OCT).SETTING: Prince Charles Eye Unit, King Edward VII Hospital, Windsor, United Kingdom.METHODS: Thirty-four CCIs in 34 adult eyes were examined prospectively using the Carl Zeiss Visante anterior segment OCT imaging system within 1 hour of uneventful phacoemulsification cataract surgery. The CCIs were created using 4 widths of stainless steel blades (2.20 mm, 2.50 mm, 2.75 mm, and 3.20 mm). Immediately afterward, a Seidel test, an inverse Seidel test, and intraocular pressure (IOP) measurements were performed independently. The OCT images were randomized and masked before evaluation. Approval was obtained from appropriate research and ethics committees.RESULTS: The mean CCI length was 1.61 mm +/- 0.26 (SD) (range 1.10 to 2.25 mm). The mean incision angle was 40.7 +/- 9.43 degrees (range 24 to 56 degrees). Five CCI architectural features were noted with the following frequencies: epithelial gaping (12%), endothelial gaping (41%), endothelial misalignment (65%), local detachment of Descemet's membrane (62%), and loss of coaptation (9%). A reduction in wound apposition up to 20% was caused by endothelial gaping and up to 25%, by loss of coaptation, in a bidimensional image. The mean postoperative IOP was 16.1 +/- 9.02 mm Hg (range 3 to 46 mm Hg). The IOP was lower with local detachment of Descemet's membrane (P
