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.
泪小点成形术是治疗泪小点狭窄的常用方法，于 1853 年由威廉·鲍曼爵士首次描述。该手术有多种术式，包括 1 切、2 切、三角 3 切、矩形 3 切和 4 切。过去十年，借助电子显微镜和分子技术，人们对泪小点的解剖和生理有了更深入的了解。微创手术在原发性疾病中的应用日益增多，同时成功保留了泪小点和泪小管的生理功能。本文综述了目前的解剖和生理学证据，提出了另一种观点。鉴于我们认识的不断发展，现在可能需要重新讨论常规行泪小点成形术的做法。
