: To report the occurrence of dry eye after Lester Jones tube (LJT) insertion. : Retrospective case series from a single unit. The dacrocystorhinostomy (DCR) was carried out using both endoscopic and external approachs; however, insertion of LJT used the same method as either a primary or secondary procedure. Dry eye as an outcome measure was only confirmed after three separate visits using the presence of both patient symptoms and dry eye signs with none preceding tube insertion. : Fifty-four patients underwent consecutive LJT insertion over a 5-year period. Mean age was 52.6 (range 25-73 years). The majority were female 39 (72%). Revision surgery was required in 15 (27%) with 3 or more occurring in 6 (11%). In total, 9 patients developed dry eyes (17%). Mean age was 60 (range 47-73) years, 5 females and 4 males. Four of the dry eye individuals had undergone primary LJT insertion and the remaining five received their first LJT 6-24 (mean 15) months post-DCR. Two dry eye patients had previously undergone LASIK and radiotherapy. : A risk of dry eye following LJT placement is higher than the literature suggests. This should be considered and counseled, especially in those who have underlying pre-disposing factors. Ease of removal may be a desirable attribute in such cases.
报告莱斯特·琼斯管（LJT）植入术后干眼症的发生情况。：来自单一机构的回顾性病例系列。泪囊鼻腔造口术（DCR）采用内镜和外部入路进行；然而，LJT的植入采用与初次或二次手术相同的方法。仅在三次单独就诊后，根据患者症状和干眼体征的存在情况确认干眼这一结果指标，且在植入管之前均无干眼情况。：54例患者在5年期间连续接受LJT植入。平均年龄为52.6岁（范围25 - 73岁）。大多数为女性，共39例（72%）。15例（27%）需要进行翻修手术，其中6例（11%）发生3次或更多次翻修。总共有9例患者出现干眼症（17%）。平均年龄为60岁（范围47 - 73岁），5例女性和4例男性。4例干眼症患者接受了初次LJT植入，其余5例在DCR术后6 - 24个月（平均15个月）接受了首次LJT植入。2例干眼症患者此前接受过LASIK和放射治疗。：LJT植入后发生干眼症的风险高于文献报道。应考虑到这一点并向患者提供咨询，尤其是对于那些有潜在易感因素的患者。在这种情况下，易于取出可能是一个理想的特性。
