目的：比较重力液流与主控液流2种灌注方式下行白内障超声乳化手术对青光眼患者视盘血流的影响。方法：采用随机数字表法将患者分为2组，分别为重力液流灌注组和主控液流灌注组。记录术中超声乳化累积释放能量(cumulative dissipated energy，CDE)，术后1天、1周、1个月和3个月患者最佳矫正视力(best corrected visual acuity，BCVA)、眼压、视盘血流密度及视网膜神经纤维层厚度。结果：主控液流灌注组术中CDE小于重力液流灌注组(5.6±1.3 vs 6.3±1.2，P=0.034)。术后1天重力液流灌注组视盘周围血管密度(circumpapillary vascular density，cpVD)、整个图像血管密度(whole en face image vessel density，wiVD)和视盘内血管密度(inside disc vascular density，inside disc VD)均高于主控液流灌注组(P<0.05)，其余时间点差异无统计学意义(P>0.05)。术后1周和1个月重力液流灌注组视网膜神经纤维层厚度大于主控液流灌注组(P<0.05)，术后1天和3个月未见明显差异。结论：相较于传统的重力液流灌注，主控灌注能够在青光眼患者白内障超声乳化手术中减少超声能量的使用，术后早期可减轻由术中高眼压引起的视盘炎症性充血，可以减轻对视网膜神经纤维层的影响。

Objective: To compare the influence of active versus passive phacoemulsification fluidics systems on optic disc blood flow in patients with glaucoma. Methods: Patients were divided into 2 groups by a random number table method, namely the active fluidics system group and the passive fluidics system group. The intraoperative cumulative dissipated energy (CDE) was recorded, and the best corrected visual acuity (BCVA), intraocular pressure, optic disc blood flow density and retinal nerve fiber layer thickness were measured at the follow-up of 1 day, 1 week, 1 month and 3 months. Results: During phacoemulsification, CDE in the active fluidics system group was lower than that in the passive fluidics system group (5.6±1.3 vs. 6.3±1.2, P=0.034). One day after the surgery,the circumpapillary vessel density (cpVD), whole image vessel density (wiVD) and inside disc vascular density(inside disc VD) in the passive fluidics system group were higher than those in the active fluidics system group(P<0.05), and the differences were not statistically significant at the rest of the follow-ups (P>0.05).The retinal nerve fiber layer in passive fluidics system group was thicker than that in active fluidics system group at the follow-ups of 1 week and 1 month (P<0.05), and the difference was not statistically significant at the follow-up ofs 1 day and 3 months. Conclusion: Compared with the traditional passive fluidics system, the active fluidics system can reduce the CDE during phacoemulsification surgery. It can reduce the inflammatory congestion of the optic disc caused by intraoperative high intraocular pressure on the early postoperative stage. In addition, it can also protect retinal nerve fiber layer.

Objective: To explore the application effect of job demand-oriented training model in specialized training of sterile supplying for nurses in the ophthalmic operation room. Methods: A total of 44 nurses who would work in the operating room were randomly divided into the experimental group (n=23) and control group (n=21). Based on the three industrial standards of Central Sterile Supply Department (CSSD) and the technical specifications of disinfection in hospital, and targeting the job requirements of operating room nursing, the experimental group formulates specific training contents and adopts various training methods. The experimental group was transferred to the operating room after being trained in CSSD for 3 months and passing the examination. The control group was transferred directly to the operating room. The degree of satisfaction from the teachers of operating room to new nurses was used as the evaluation index. Results: All the 23 students passed the examination of theoretical knowledge and technical operation, and the small lectures were completed successfully. The degree of satisfaction from teachers in operating room to trainees was obviously higher than that of untrained nurses. Conclusion: The establishment of job demand-oriented training model in specialized training of sterile supplying for nurses in ophthalmic operation room is helpful to improve the work adaptability of the newly-hired nurses in the operation room. It also helps the nurses in the operation room to enhance the management ability on the specialized instruments.

目的：探讨以Base-out恢复点为目标手术量的急性共同性内斜视(acute acquired comitant esotropia，AACE)的治疗效果。方法：随诊以Base-out恢复点为目标手术量、且术后随访时间超过4个月的AACE患者，分析术前及末次随诊时斜视度、双眼视功能参数及术后立体视恢复的影响因素。结果：将43例患者纳入研究，其中男27例(63%)，女16例(37%)，手术年龄9~53(23.7±11.4)岁，术前斜视持续时间3个月~11年(24.8±24.5个月)，术后随访4~62(15.8±14.5)个月。术前Base-out恢复点比斜视度更大[远距差值(9.3±6.9) PD，P<0.001；近距差值(11.4±6.7) PD，P<0.001]；术前视远和视近斜视度分别为(38.4±13.2) PD和(37.6±13.7) PD，末次随诊时视远和视近斜视度分别为(0.74±2.4) PD和(0.70±2.4) PD(均P<0.001)，38例(88%)患者无眼位偏斜，5例(12%)有轻微内隐斜视。末次随诊时视远和视近立体视锐度显著改善(P<0.001)，末次立体视功能与术前近距立体视水平和术前斜视持续时间相关。结论：以Base-out恢复点为目标手术量的AACE手术能取得较好的矫正效果，未见眼位过矫者；术后立体视恢复与术前近距立体视和术前斜视持续时间相关，提示适当早期手术可能有助于术后立体视功能的恢复。

Objective: To evaluate the effect of using the amount of base-out (BO) recovery point as the surgical target for acute acquired comitant esotropia (AACE). Methods: Patients with AACE underwent surgery based on the target angle of the base-out recovery point and were followed up at least 4 months. The deviation, binocular functions before and after the surgery were analyzed and the factors related the post-operative stereopsis were evaluated. Results: Totally 43 patients were included in the study, including 27 males (63%) and 16 females (37%), aged from 9 to 53 years (23.7±11.4 years), duration of preoperative strabismus ranged from 3 months to 11 years (24.8±24.5 months), and postoperative follow-up ranged from 4 to 62 (15.8±14.5 months). Both distant and near pre-operative Base-out recovery point were larger than the angle of esotropia [(9.3±6.9) PD for distant; (11.4±6.7) PD for near, both P<0.001]. The pre-operative esotropia for distant and near viewing were (38.4±13.2) PD and (37.6±13.7) PD respectively and reduced to (0.74±2.4) PD and (0.70±2.4) PD at the last visit time (P<0.001). Thirty-eight cases were orthosia without any phoria and five cases still had some esophoria or minimal esotropia at the last visit. The stereoacuity improved significantly after the surgery. The post-operative stereopsis significantly correlated with the pre-operative stereopsis and the duration from onset of esotropia to the time of surgery. Conclusion: The acute acquired comitant esotropia can be corrected with strabismus surgery based on the target angle of base-out recovery point. The post-operative stereopsis correlated with the pre-operative stereo function and the time of esotropia lasting. It suggested the earlier esotropia was corrected the better the stereopsis recovered.

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：了解白内障手术患者的临床分布特点，为基层医院白内障防治工作提供信息参考。方法：选取2019年1月至2019年1 2月在锦州医科大学附属第三医院眼科手术医治的白内障患者892例1 008眼。查阅相关病历资料，收集姓名、性别、年龄、手术眼别、入院时间、有无糖尿病史；术前视力、角膜内皮细胞密度、眼轴、晶状体混浊类型及白内障病因；手术方式、人工晶状体(intraocular lens，IOL)、术中并发症；术后第1天眼压、视力、眼部情况，进行统计学描述及分析。结果：入 选892例1 008眼，其中男357例401眼，女535例607眼，年龄(71.17±10.28)岁，90.7%的患者病因为年龄相关性白内障。入院时间集中在3~6月和9~12月。不同年龄段白内障患者具有各自的眼部特征。白内障类型与年龄差异有统计学意义(P<0.05)，相比皮质性、后囊膜下性，核性白内障患者入院年龄偏大。白内障类型与性别、有无糖尿病史差异无统计学意义(P >0.05)。白内障患者选择最多的手术方式是超声乳化吸除术联合IOL植入术，术中并发症少，术后恢复快。结论：白内障的防治工作任重道远。手术多为年龄相关性白内障患者，入院时多年龄偏大，视力偏低，错失了手术最佳时机。不同年龄段、不同类型白内障患者具有不同的特征。超声乳化吸除术因其优势成为患者首选手术方式。

Objective: To understand the clinical distribution characteristics of cataract surgery patients and provide reference for cataract prevention and treatment in primary hospitals. Methods: From January 2019 to December 2019, 892 cataract patients (1 008 eyes) were selected from the Department of Ophthalmology, Third Affiliated Hospital of Jinzhou Medical University. Medical records were collected, including patient’s name, gender, age, surgical eye, admission time and history of diabetes, preoperative vision, corneal endothelial cell density, eye axis, phacoscotasmus type and cataract etiology, surgery method, intraocular lens, intraoperative complications, intraocular pressure, visual acuity and eye recovery on the first day after operation. These data were statistically described and analyzed. Results: A total of 892 cataract patients (1 008 eyes) were included, including 357 males (401 eyes) and 535 females (607 eyes), with the average age of (71.17±10.28) years old. The 90.7% patients cause of disease was age-related cataract. Admission time of all patients was mainly in March–June and September– December. Cataract patients of different ages had their own ocular characteristics. There was a statistically significant difference between the type of cataract and age (P<0.05). Compared with the cortical patients and posterior subcapsular patients, nuclear cataract patients were older at admission. There was no significant difference in the type of cataract between the gender and the patients with diabetes or not (P>0.05). The most frequently selected surgical method for cataract patients was phacoemulsification and intraocular lens implantation, which has the advantages of less intraoperative complications and rapid postoperative recovery. Conclusion: We still have a long way to go in the prevention and treatment of cataract. Most of the operations were performed on age-related cataract patients, and most of them were older and had low vision when they were admitted to hospital, so the optimal timing of the operation was missed. Patients of different age groups and different types of cataract have different characteristics. Phacoemulsification is the first choice because of its own advantages.

目的：评价手术视频辅助Wetlab眼睑手术教学的效果。方法：回顾性分析2021年4月至2021年9月在中山大学中山眼科中心住院医师规范化培训学员中使用全眼模型开展Wetlab外眼手术教学的情况。对照组(12人)采用传统教学方法，实验组(15人)在传统教学方法的基础上引入手术视频辅助教学，对学员第3、6、9次练习视频进行评分，分析教学效果。结果：2组学员的基线水平与学习曲线相似，练习第3次到第6次之间评分提高快(对照组P3~6=0.001，实验组P3~6<0.001)，第6次到第9次之间提高速度放缓(对照组P6~9=0.007，实验组P6~9=0.012)。对照组学员在练习第3次用时更长[(80.3±16.1) min]，随着练习次数增多，用时逐渐缩短并保持稳定(P3~6=0.040，P6~9=0.886，P3~9=0.020)，而实验组学员在练习第3次用时更短[(71.7±15.0) min]，练习过程中保持稳定(P3~6=0.568，P3~9=0.519)。结论：手术视频辅助教学有助于学员熟悉手术操作，提高练习效率。

Objective: To assess the efficacy of video-assisted Wetlab eyelid surgery teaching. Methods: From April 2021 to September 2021, the porcine orbit model was used to conduct a Wetlab teaching course on eyelid surgeries among trainees of standardized training for residents in Zhongshan Ophthalmic Center, Sun Yat-sen University. The control group (12 trainees) used conventional teaching methods. Video-assisted teaching was offered to the test group (15 trainees) based on conventional teaching methods. The videos records of the 3rd, 6th, and 9th practices were scored to analyze the teaching efficiency. Results: Trainees from the 2 groups showed a simila baseline and learning curve. Rapid improvement was found between the 3rd and 6th practice (P3–6=0.001 in control group, P3–6<0.001 in test group). The increment was slower between the 6th and 9th practice (P6–9=0.007 from control group, P6–9=0.012 from test group). Longer time was required by trainees from the control group at the 3rd practice [(80.3±16.1) min]. As they practiced more, the time required gradually decreased and remained stable (P3–6=0.040, P6–9=0.886, P3–9=0.020 from control group). Trainees from the test group spent less time at the 3rd practice [(71.7±15.0) min]. The time remained stable during all practices (P3–6=0.568, P3–9=0.519 from test group). Conclusion: Video-assisted teaching can help trainees get familiar with surgical operations and improve the efficiency of practices.
