A clear corneal incision (CCI) is the most commonly used entrance site in modern phacoemulsification cataract surgery. Despite some initial concerns about increased endophthalmitis rates through a self-sealing CCI, recent literature suggests that the risk of infection with proper wound construction and all other necessary precautions is minimal. The technique of creating a clear corneal incision has, with recent developments in corneal imaging, undergone critical appraisal leading to a better understanding of incision architecture. Many surgeons operate through smaller incisions, and they have a wide choice of surgical instruments to create their corneal incisions. The aim of this review is to discuss the history and the current status of clear corneal incision creation, the design and materials of surgical blades, and the current trends in manufacturing and sustainability. Although disposable instruments have some advantages and are very popular, recycling, if possible, and avoiding unnecessary plastic waste are important considerations. In any case, the step of CCI is a small one for the surgeon, but a big one for the eye. That is why it has to be done with the utmost precision and in-depth knowledge is important.
角膜缘透明切口（CCI）是现代超声乳化白内障手术中最常用的入路。尽管最初人们担心通过自密封 CCI 会增加眼内炎的发生率，但最近的文献表明，通过正确的伤口构建和所有其他必要的预防措施，感染的风险极小。随着角膜成像技术的最新发展，角膜缘透明切口的技术已经受到了严格的评估，从而更好地了解了切口结构。许多外科医生通过更小的切口进行手术，并且有多种手术器械可供选择来创建他们的角膜切口。本文旨在讨论角膜缘透明切口的历史和现状、手术刀片的设计和材料，以及制造和可持续性的当前趋势。尽管一次性器械有一些优势，并且非常受欢迎，但如果可能的话，回收利用和避免不必要的塑料废物是需要考虑的重要因素。无论如何，对于外科医生来说，CCI 步骤是一个很小的步骤，但对于眼睛来说却是一个很大的步骤。这就是为什么必须非常精确地进行操作，并且深入了解相关知识非常重要。
