Several methods for occluding the lacrimal canaliculi to prevent spontaneous drainage have been described for the treatment of dry eye. These techniques have been either of short duration or irreversible. We have developed a technique in which the vertical portion of the lacrimal canaliculus is transferred anteriorly, and the lacrimal punctum is placed between the eyelashes, where it is out of the lacrimal meniscus and therefore nonfunctional. If the quantity of lacrimal secretion improves, the vertical portion of the lacrimal canaliculus may be returned to its original site, allowing normal lacrimal flow. The technique was successful in 12 puncta of seven patients with more than 5 years of follow up. The operation was easily reversed in the two puncta of one patient who complained of epiphora after lacrimal secretion had improved, allowing spontaneous tear drainage.
已经描述了几种用于阻塞泪小管以防止自然引流的方法来治疗干眼症。这些技术要么持续时间短，要么是不可逆的。我们开发了一种技术，其中泪小管的垂直部分向前转移，泪点置于睫毛之间，处于泪液弯月面之外，因此不起作用。如果泪液分泌量改善，泪小管的垂直部分可恢复到其原始位置，使泪液正常流动。该技术在7例患者的12个泪点中取得成功，随访超过5年。在1例患者的2个泪点中，当泪液分泌改善后患者抱怨流泪溢泪，该手术很容易逆转，使泪液自然引流。
