目的：评估Smart plug泪小管塞治疗水液缺乏型干眼的长期并发症。方法：收集汕头国际眼科中心2011至2016年门诊确诊的水液缺乏型干眼患者300例(600眼)，进行Smart plug泪小管塞治疗，随访观察术后临床并发症，中位随访时间为术后3年(术后1~5年)。结果：3例患者(3眼)术后患有泪小管炎(0.5%)，发病时间为术后1~3(中位2)年，取出泪小管塞后并给予局部抗生素滴眼液治愈。2例患者 (4眼)因植入上下泪小管塞后流泪症状不能耐受，单纯取出下泪小管塞后症状缓解(0.7%)；4例患者(8眼)因只植入下泪小管塞症状未能明显好转，1个月后再次植入上泪小管塞(1.3%)；291例患者干眼主观症状改善，有效率为97.5%，长期随访未发现并发症。结论：虽然Smart plug泪小管塞治疗水液 缺乏型干眼具有明确的疗效，但Smart plug泪小管塞植入后的长期并发症不容忽视，需要长期观察。

Objective: To evaluate the long-term complication associated with the use of the Smart plug in the treatment of aqueous tear deficiency dry eye. Methods: A total of 300 patients (600 eyes) were collected in Joint Shantou International Eye Center from 2011 to 2016, all the patients accepted the treatment with Smart plug, and were followed up for clinical complications. The median follow-up time was postoperative 3 years (1–5 years after surgery). Results: Three patients (3 eyes) developed canaliculitis, the rate was 0.5%. The median time from Smart plug insertion to the onset of canaliculitis was 2 (1–3) years, leaving the Smart plug and resolved the application of topical antibiotics. Two patients (4 eyes) could not suffer from implantation of the upper and lower Smart plug, removed the below, the ratio was 0.7%; 4 patients (8 eyes) need upper Smart plug insertion after implantation of the lower one month later, the rate was 1.3%; 291 cases of dry eye improved by long-term followup, the effective rate was 97.5%. Conclusion: Although the Smart plug is effective in the treatment of aqueous tear deffciency dry eye, the later complications of Smart plug insertion cannot be neglected and need the long-term follow-up.

目的：观察可折叠人工晶体单襻悬吊术在处理白内障超声乳化术中后囊膜破裂的临床应用效果及安全性。方法：回顾性分析 2015 年 1 月至 2016 年 12 月在南京医科大学附属无锡人民医院行白内障超声乳化术并出现后囊膜破裂的 64 例（64 眼）白内障患者，分为试验组（33 例 33 眼）和对照组。试验组行可折叠人工晶体单襻悬吊术；对照组（31 例 31 眼）行硬片式人工晶体双襻悬吊术。手术当天记录疼痛评分，并分别于术后 1 d、术后 1 周及术后 1 个月记录术眼视力、眼压、前房反应、晶体位置及并发症发生情况。结果：试验组的疼痛反应较对照组显著减轻（P < 0.05）。术后第 1 天，两组视力、眼压、前房反应差异均无统计学意义（P > 0.05）。术后 1 周试验组前房反应较对照组小（P < 0.05），两组视力、眼压差异均无统计学意义（P > 0.05）。术后 1 个月两组视力、眼压、前房反应差异均无统计学意义（P > 0.05）。试验组中 1 例（3.03%）术后第 1 天出现前房积血，2例（6.06%）出现人工晶体轻度偏位；对照组 1 例患者（3.33%）术后第 1 天出现一过性眼压增高，未发现其余并发症。结论：改良折叠型人工晶体上方悬吊术是处理白内障超声乳化术中后囊膜破裂安全可行的手术方式。

Objective: To evaluate the safety and effectiveness of foldable intraocular lens single loop suspension in the treatment of posterior capsule rupture in the phacoemulsification. Methods: Sixty-four patients (64 eyes) with posterior capsular rupture during cataract surgery from January 2015 to December 2016 were selected and divided into an experimental group (33 patients, 33 eyes) and a control group (31 patients, 31 eyes). The experimental group received foldable intraocular lens single loop suspension, and the control group received hard plate intraocular lens suspension. Pain score was recorded on the day of operation; visual acuity, intraocular pressure, anterior chamber response, crystal location and other complications were recorded separately on the dayafter operation, 1 week and 1 month after operation. Results: Patients felt less painful in the experimental group (P < 0.05). There was no significant difference in visual acuity, intraocular pressure and anterior chamber response between the two groups the day after operation (P > 0.05). But the anterior chamber reaction in the control group was more serious than in the experimental group when observed one week and one month after operation (P < 0.05), and there was no significant difference in visual acuity, intraocular pressure and anterior chamber response between the two groups. In the experimental group, 1 patient (3.03%) had hyphema, and 2 patients (6.06%) had a slight tilt of the intraocular lens. In the control group, 1 patient (3.33%) had transient intraocular hypertension. Conclusion: Foldable intraocular lens single loop suspension is a safe and feasible operation to treat posterior capsular rupture in phacoemulsification.
