Abstract：
Punctoplasty is a common procedure in the management of punctal stenosis and was first described by Sir William Bowman in 1853. Several types of punctoplasty are described, and include 1-snip, 2-snip, triangular 3-snip, rectangular 3-snip and 4-snip procedures. The understanding of the anatomy and physiology of the punctum has greatly improved in the last decade aided by electron microscopic and molecular techniques. The use of minimally invasive modalities for primary cases is on the rise with successful preservation of the physiological functions of the punctum and canaliculus. The paper reviews the current anatomical and physiological evidence to present an alternative perspective. Given our evolving understanding, it may be time to debate the practice of performing routine punctoplasty.
摘要：
泪点成形术是泪点狭窄的常见治疗方法，于1853年由WilliamBowman爵士首次描述。描述了几种类型的穿刺成形术，包括1-snip，2-snip,三角形3-snip,矩形3-snip和4-snip程序。在电子显微镜和分子技术的帮助下，对泪点的解剖学和生理学的理解在过去十年中有了很大的提高。随着成功保留泪点和泪小管的生理功能，对原发性病例的微创方式的使用正在增加。本文回顾了当前的解剖学和生理学证据，以提出另一种观点。鉴于我们不断发展的理解，也许是时候讨论进行常规点状成形术的做法了。
