目的：了解行全飞秒激光小切口角膜基质透镜取出术(small incision lenticule extraction，SMILE)患者围手术期的体验感受。方法：采用定性调查的方法，选取广东省某医院的15名行SMILE的患者，进行半结构式访谈，将患者围手术期体验归纳为顾虑、紧张、疼痛、担心、放松5个主题概念，用现象学分析法整理、分析资料。结果：把5种体验汇总制成韦恩图，通过韦恩图提炼发现有1人有围手术期5种感受，3位有紧张、疼痛、担心、放松4种心理感受，2位只有紧张的感受，而无其余感受。结论：行SMILE患者的围手术期具有多种体验感受，分析不同感受状态和因素，为眼科医护人员对于寻求SMILE手术的患者做好围手术期的服务提供依据。

Objective: To investigate the perioperative experience after small incision lenticule extraction (SMILE). Methods: A semi-structured interview was conducted in 15 patients who underwent SMILE surgery in Zhuhai People’s Hospital.The data were collected and analyzed by phenomenological analysis. Results: The perioperative feelings of patients were summarized into five categories: concern, tension, pain, worry and relaxation. These feelings were compiled and extracted by Venn diagram. One patient had all five categories of feelings during the perioperative period. Three patients experienced four psychological feelings of tension, pain, worry and relaxation, and 2 patients had only nervous feelings during the full femtosecond operation period. Conclusion: Patients undergoing SMILE have avariety of experience feelings during perioperative period. Analysis of different feeling states and factors will provide evidence for ophthalmic medical staff to provide perioperative services for patients seeking SMILE surgery.

目的：评估右美托咪定复合舒芬太尼用于老年青光眼患者经巩膜二极管激光睫状体光凝术 (transscleral diode laser cyclophotocoagulation，TDLC)术后自控静脉镇痛(patient-controlled intravenous analgesia，PCIA)的安全性和有效性。方法：选择行TDLC术老年青光眼患者80例，采用随机数字表法将患者分为SD组(n=40)和S组(n=40)。SD组术后PCIA采用舒芬太尼1.5μg/kg+右美托咪定1.5 μg/kg+托烷司琼4mg；S组采用舒芬太尼2μg/kg+托烷司琼4mg。将相应药物置入生理盐水配成100mL混合液加入电子镇痛泵，手术结束即刻行PCIA至术后24h。观察比较两组患者基本情况和手术情况，比较术前(T0)、术后即刻(T1)、术后6h(T2)、术后12h(T3)和术后24h(T4)患者的收缩压(systolic blood pressure，SBP)、舒张压(diastolic blood pressure，DBP)、心率(heart rate，HR)、NRS疼痛评分、Ramsay镇静评分及非手术眼的眼内压(intraocular pressure，IOP)，比较术后恶心呕吐、呼吸抑制、躁动等不良反应及使用其他辅助镇痛药物的情况。结果：两组患者基本情况和手术情况的差异无统计学意义。两组各时点DBP、非手术眼IOP及NRS评分差异无统计学意义。SD组T3、T4时点SBP，T2、T3、T4时点HR以及T2、T3时点Ramsay评分均低于S组，差异有统计学意义(P<0.05)。两组患者发生不良反应的总例数差异无统计学意义，但SD组恶心呕吐(1例)和烦躁(2例)发生率均低于S组(分别为6例和9例)，差异有统计学意义(P<0.05)。两组患者呼吸抑制和眩晕嗜睡发生率以及使用其他辅助镇痛药物例数差别无统计学意义，SD组舒芬太尼使用量低于S组(P<0.05)。结论：采用右美托咪定1.5μg/kg复合舒芬太尼1.5μg/kg行PCIA时不影响非手术眼IOP，可安全有效地应用于老年青光眼患者TDLC术后镇痛。

Objective: To evaluate the safety and efficacy of dexmedetomidine combined with sufentanil for postoperative patient-controlled intravenous analgesia (PCIA) after transscleral diode laser cyclophotocoagulation (TDLC) in elderly patients with glaucoma. Methods: Eighty elderly glaucoma patients undergoing TDLC were selected and randomly divided into a SD group (n=40) and a S group (n=40) by random number table method. In SD group (n=40), sufentanil 1.5 μg/kg, dexmedetomidine 1.5 μg/kg and tropisetron 4 mg were used for postoperative PCIA, and sufentanil 2 μg/kg and tropisetron 4 mg were used in S Group (n=40). The corresponding drugs in saline solution was added into 100 mL solution with electronic analgesia pump. PCIA was performed immediately after the operation until 24 h after the operation. The basic condition and operation situation of the two groups were observed and compared, and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), NRS pain score, Ramsay sedation score and non-operation eye intraocular pressure (IOP) at preoperative (T0), after operation (T1), postoperative 6 h (T2), 12 h after operation (T3) and 24 h after operation (T4) were compared, and postoperative adverse reactions such as nausea and vomiting, respiratory depression, restlessness and use of other auxiliary analgesic drug were also compared. Results: There was no significant difference between two groups of patients’ basic and surgical conditions. There was no significant difference between two groups at each time point DBP, non-operation eye IOP and NRS score. SBP at T3 and T4, HR at T2, T3 and T4, and Ramsay score at T2 and T3 in SD group were lower than the S group, the difference was statistically significant. There was no significant difference in the total number of adverse reactions between two groups, but the incidence of nausea and vomiting and restlessness in group SD were lower than those in group respectively, the difference was statistically significant (P<0.05). There was no significant difference between the two groups in the incidence of respiratory depression, dizziness, lethargy and the use of other auxiliary analgesics. The sufentanil usage in group SD was lower than that in group S (P<0.05). Conclusion: PCIA with dexmedetomidine 1.5 g/kg combined with sufentanil 1.5 g/kg does not affect the non-operation eye IOP. It can be safely and effectively applied to postoperative analgesia for elderly patients with glaucoma after TDLC

目的：对比两种不同部位M22优化脉冲激光治疗方法治疗睑板腺功能障碍(meibomian gland dysfunction，MGD)所致干眼的疗效。方法：回顾性分析汕头博德眼科医院干眼门诊患者105例，包括常规治疗组和改良治疗组两个组别，常规治疗组激光部位为下睑，改良治疗组激光部位为联合上下睑，所有患者行M22优化脉冲光治疗一个疗程(每月1次，共3次)，治疗前后均采用keratograph 5M干眼分析仪分析评估患者的泪河高度情况、泪膜破裂时间(break-up time，BUT)、角膜荧光染色(corneal fluorescence staining，CFS)和睑板腺排出能力等参数。采用t检验分析对比治疗前后变化情况。结果：患者治疗后泪河高度较强脉冲光治疗前明显增高，BUT时间延长，角膜荧光染色和睑板腺排出能力评分均有好转，每组治疗后与治疗前差异有统计学意义(P<0.01)，两组间治疗前后各参数差异比较均没有统计学意义。结论：两种不同部位M22优化脉冲激光治疗方法在治疗MGD导致的干眼方面有较好的效果，是较安全有效地治疗方法，两种不同方法治疗效果无明显差异。

Objective: To study the efficacy of two methods of M22 optimal pulsed technology in the treatment of dry eye caused by meibomian gland dysfunction (MGD). Methods: A total of 105 patients collected from Shantou Balder Eye Hospital were divided into two groups. The treatment position of the conventional group was lower eyelid, the other group was combined with upper and lower eyelid. All patients accepted M22 Optimal Pulsed Technology treatment for three times, once a month. Keratograph 5M dry eye analyzer was used to assess the height of tears river, break-up time (BUT), corneal fluorescence Staining(CFS)and meibomian gland expressibility. The results before and after laser treatment were compared using t-test in this study. Results: After treatment, the height of tear river, BUT, CFS and meibomian gland expressibility were improved. There was a statistically significant difference between each group after and before treatment (P<0.01). There was no significant difference before and after treatment between the two groups. Conclusion: The two methods of M22 Optimal Pulsed Technology are effective in treating dry eyes caused by MGD. There is no significant difference in the therapeutic effect between two methods.

目的：通过随机对照试验，观察氦氖激光在喀什地区弱视儿童中的治疗效果。方法：选取2016年2月至2018年11月期间就诊喀什地区第一人民医院符合纳排标准的弱视儿童，按随机数字表法，分为试验组(氦氖激光+弱视常规治疗组)与对照组(弱视常规治疗组)，比较两组的弱视治疗效果。结果：本试验成功纳入弱视儿童111例(177眼)，其中试验组61例(97眼)，对照组50例(80眼)。与对照组相比，汉族试验组弱视儿童效果明显(P=0.023)，维吾尔族试验组弱视儿童未见明显疗效(P=0.481)；试验组与对照组在喀什地区不同年龄、不同弱视程度、不同弱视类型及不同弱视眼数儿童中未见明显差异(P>0.05)。结论：氦氖激光治疗喀什地区弱视儿童作用有限，为避免过度医疗，不建议在南疆地区开展。

Objective: To observe the therapeutic effect of helium-neon laser in amblyopia children in Kashgar by a randomized controlled trial. Methods: Amblyopia children who met eligibility criteria during February 2016 to November 2018 were selected and divided into two groups according to random number table: test group(helium-neon laser + conventional treatment for amblyopia) and control group (conventional treatment for amblyopia). The effects of amblyopia treatment were compared between two groups. Results: One hundred and eleven amblyopic children (177 eyes), including 61 children (97 eyes) of the test group and 50 children (80 eyes) of the control group were included in this study. The effect of helium-neon laser was significant in Han children (P=0.023), but not in Uygur children (P=0.481) in the test group compared with the control group.Conclusion: Helium-neon laser has limited effect in treating children with amblyopia in Kashgar region. To avoid over-treatment, it is not recommended to perform it in southern Xinjiang.
