目的：探讨超声乳化晶状体吸除联合囊袋上经巩膜缝线固定人工晶状体(intraocular lens,IOL)植入术治疗球形晶状体(microspherophakia,MSP)的有效性和安全性。方法：采用回顾性分析，选取2019年1月至 2020年6月期间在复旦大学附属眼耳鼻喉科医院进行治疗的MSP患者37例(37眼)，随机分为两组，纳入行超声乳化晶状体吸除联合囊袋上巩膜缝线固定IOL植入术(supra-capsular and scleral-fixated intraocular lens implantation,SCSF-IOL)的MSP患者20例(20眼)和行超声乳化晶状体吸除联合改良型囊袋张力环植入术(transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation,MCTR-IOL)的MSP患者17例(17眼)，观察两组术后最佳矫正视力及并发症等情况。结果：两组术后最佳矫正视力比术前均有改善(P<0.001)，而组间比较差异无统计学意义(P=0.326)。两组的IOL倾斜度相当(P=0.216)。预防性Nd:YAG激光后囊膜切开术在SCSFIOL术后1周至1个月进行。在SCSF-IOL组，2眼(10.00%)需要重复激光治疗，1眼(5.00%)出现囊口偏心。后囊膜混浊是MCTR组最常见并发症(6眼,35.29%)。随访期间两组均未出现IOL脱位、继发性青光眼和视网膜脱离。结论：SCSF-IOL是治疗球形晶状体的简单易行的手术方式，疗效与MCTR-IOL相当。Nd:YAG激光后囊膜切开术是预防SCSF-IOL术后囊袋并发症的必要手段。

Objective: To investigate the efficacy and safety of phacoemulsification combined with supra-capsular and scleral-fixated intraocular lens (IOL) implantation in the treatment of microspherophakia (MSP). Methods: by retrospective analysis, 37 MSP patients (37 eyes) who were treated in our hospital from January 2019 to June 2020 were randomly divided into two groups, including 20 MSP patients (20 eyes) who treated by SCSF-IOL and 17 MSP patients (17 eyes) who treated by transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation (MCTR-IOL). The best corrected vision and complications were observed. Results: the best corrected vision was significantly improved in both groups (P < 0.001), but there was no remarkable difference between the two groups (P = 0.326). The IOL tilt was also comparable (P = 0.216). Prophylactic Nd: YAG laser posterior capsulotomy was performed from 1 week to 1 month after the SCSF-IOL procedure. In the SCSF-IOL group, two eyes (10.00%) needed repeated laser treatment, and one eye (5.00%) had a decentered capsule opening. Posterior capsular opacification was the most common complication (6, 35.29%) in the MCTR group. No IOL dislocation, secondary glaucoma, or retinal detachment was observed during follow-up. Conclusions: SCSF-IOL is a simple and viable surgical option for managing MSP and is comparable with the MCTR-IOL. Nd: YAG laser posterior capsulotomy is a necessary mean to prevent residual capsule complications after the SCSF-IOL procedure.

目的: 分析高度近视眼行白内障摘除及后房型人工晶状体植入术后并发裂孔源性视网膜脱离的发生率、相关危险因素及临床特点。

方法 : 回顾性分析高度近视眼行白内障摘除及后房型人工晶状体植入术患者 146 例(232 只眼) 。裂孔源性视网膜脱离在术后随访的3年时间发生。所有眼均进行了详细的眼科检查, 包括: 最佳矫正视力、眼底检查、A 超眼轴长度测量。

结果: 15 只眼发生裂孔源性视网膜脱离(6.4%) , 均需行玻璃体视网膜手术进行视网膜复位。从白内障手术到发生视网膜脱离的平均时间为10 ± 9 个月(0.5～32 个月) 。视网膜脱离经手术治疗后视力为手动 /10 cm～0.06, 12 只眼(80%) 最终视力低于白内障术前。术中后囊膜破裂与术后视网膜脱离的发生显著相关 (P < 0.01) , 60%(9/15) 的视网膜脱离患者术中发生了后囊膜破裂。

结论: 高度近视眼白内障术后并发裂孔源性视网膜脱离的发生率为 6.4%, 其预后差。术中发生后囊膜破裂患者术后发生视网膜脱离的危险性更高, 对术中后囊膜破裂患者需密切随访。

Aim: To analyze the clinical characteristics, incidence and risk of retinal detachment (RD) after cataract surgery and posterior chamber intraocular lens implantation in high myopic patients.

Methods:The medical records of 146 high myopic patients (232 eyes) who underwent cataract surgery and posterior chamber intraocular lens implantation were studied retrospectively. The development of RD was followed up over a 3-year period, and its characteristics were determined. All of the eyes received a comprehensive ophthal-mological examination, including best-corrected visual acuity measurements, a dilated fundus examination and axial length measured by A-scan ultrasonography.

Results: RD developed in 15 eyes of 15 patients. All the 15 eyes needed vitreo-retinal surgery. The mean interval between cataract surgery and the development of RD was 10 ± 9 months (range 0.5～32 months) . The visual results of the eyes after anatomical successful vitreo-retinal surgery ranged from finger count /10 cm to 0.06. 80% (12/15) of the eyes had a worse vision after the surgery than that before cataract surgery. Posterior capsular tear were associated significantly with RD (P < 0.01). Approximately 60%( 9/15) of retinal detachment was attributable to posterior capsule tear during cataract surgery.

Conclusion: Incidence of RD in high myopic patients after cataract surgery was 6.4%. RD was the potentially serious complication and tended to develop more frequently in eyes with posterior capsular rupture during cataract surgery. It is crucial to examine retinal status after cataract surgery and to have a close follow-up to prevent retinal complications, especially for patients with posterior capsular disruption. 

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段扩大疾病，表现为大角膜、角膜厚度正常或轻中度变薄、前房明显加深、睫状环扩大和悬韧带松弛。早期症状可仅表现为角膜散光和屈光不正等，并发性白内障和晶状体脱位是AM患者视力下降的主要原因。眼前段解剖结构的异常使AM患者的白内障手术具有很大的挑战性。首先，极端前房深度引起的有效晶状体位置(ELP)预测误差及公式选择不当是导致其术后较大屈光误差的主要原因；其次，悬韧带松弛易导致晶状体脱位、后囊膜破裂和玻璃体脱出等术中并发症的发生；由于超大囊袋及悬韧带松弛，人工晶状体(IOL)偏心甚至脱位也是术后常见的并发症。因此，需根据患者悬韧带情况、晶状体混浊程度采取合适的手术方式及谨慎选择IOL的类型。采用手法小切口晶状体囊外摘除术，可避免超声乳化的高灌注压对悬韧带的进一步损伤，增加手术的安全性；植入光学面及襻宽大的IOL术后具有较好的稳定性；新公式如Barrett Universal Ⅱ、Kane和EVO等公式具有较好的屈光预测准确性。然而，目前关于AM患者的白内障手术治疗报道仍属于个案报道，未来还需要更大样本量的临床研究进一步证实。

Objective: To analyze the reasons for not performing laser refractive keratomileusis surgery among refractive surgery candidates under regular preoperative examination. Methods: The patients with myopia examined in the Center of Ophthalmology in the First Affiliated Hospital of Anhui Medical University Laser between January 2015 and June 2017 were selected, the reasons for not performing laser refractive keraomileusis after regular preoperative examination were analyzed. Results: A total of 2 875 patients requested refractive surgery and 2 054 (71.4%) of them received refractive surgery. Among 821 (28.6%) patients who did not get laser refractive keratomileusis, 462 (56.3%) were male and 359 (43.7%) were female, aged 18–51 years (range, 23.69±5.85 years). The most common reason for not offering refractive surgery were social psychological factors (59.0%), low central corneal thickness (22.2%), high myopia (12.2%), high intraocular pressure (2.3%), poor corrected visual acuity (1.6%), corneal topography anomaly (1.3%), retinal disease (0.9%), corneal (0.4%) and other diseases (0.2%). Conclusion: Reasons for not performing refractive surgery are quite diverse. Social psychological factors and inadequate corneal thickness were the most common reasons in the present study. Careful preoperative examination, strictly mastering indications and contraindications and full doctor-patient communication should be done for the safety of surgery.

先天性白内障是严重影响婴幼儿视功能的疾病。随着白内障手术和人工晶状体植入手术技术的发展，先天性白内障患者术后多可获得高质量的视觉康复。然而，如何更好防治手术相关的不良事件和并发症、先天性白内障伴随的其他眼部发育不良疾病的治疗以及形觉剥夺性弱视的治疗，仍然是先天性白内障手术后需要重视的临床问题。

      封面展示的是双眼先天性白内障术后继发青光眼(左眼)与正常眼(右眼)的对比示意图。该并发症起病隐匿、难以预测，是先天性白内障术后二次致盲的首要原因。针对这一术后并发症，美国婴儿无晶状体眼治疗研究组 (infant aphakia treatment study, IATS)将儿童白内障术后青光眼相关不良事件(glaucoma-related adverse events,GRAEs，包括了青光眼和可疑青光眼)定义为：1)青光眼：眼压>21 mmHg(1 mmHg=0.133 kPa)，且有以下一种或以上的解剖学改变：(a)角膜直径增加；(b)双眼不对称进行性近视漂移伴角膜直径和(或)眼轴的增加；(c)视杯直径进行性增大，杯盘比增加≥0.2；(d)必须进行手术才能控制眼压。2)可疑青光眼：停用局部糖皮质激素(激素)后连续2次眼压>21 mmHg，或可通过抗青光眼药物控制眼压，但无上述任何青光眼的解剖改变。所以，如何更精准地预防该术后并发症，防止对患儿视功能造成进一步的损害，是目前关键的临床问题。

       因此，文章对先天性白内障摘除及人工晶状体植入术后继发性青光眼和可疑青光眼的发生、相关危险因素、治疗和预防的手段进行总结，以期进一步提高对先天性白内障术后高眼压和青光眼防治的认识，减少术后并发症对患儿视功能造成的进一步损害。

This article provides a comprehensive overview of the occurrence, risk factors, treatment and prevention of high intraocular pressure and secondary glaucoma after congenital cataract and intraocular lens implantation. Its aim is to enhance the comprehension of preventive and therapeutic measures for high intraocular pressure and glaucoma after congenital cataract surgery, thereby minimizing potential postoperative complications and preserving visual function.

目的：比较单一EYESi虚拟手术模拟器(Dry-lab)、Wet-lab以及两种方式联合教学在超声乳化白内障吸除显微手术培训中的效果及差异，以期探索更科学高效的教学方式。方法：选取中山大学中山眼科中心接受住院医师规范化培训的1年级住院医师18名，随机分为Dry-lab组、Wet-lab组和联合组，每组各6人，分别接受8次有效Dry-lab训练、8次Wet-lab训练、4次有效Dry-lab训练联合4次Wet-lab训练。培训前后问卷调查评估三种教学方式的模拟效果与学员满意度，并在猪眼模型上考核超声乳化白内障吸除手术的三个主要步骤，以评估学员的培训效果。结果：Dry-lab与Wet-lab训练均能有效帮助学员学习使用显微器械，操作手感较好。但在立体感(P=0.007)、与人眼操作相比近似度(P<0.001)以及对掌握技术的帮助度(P=0.003)上，Wet-lab优于Dry-lab训练；而在缩短培训用时(P<0.001)上，Dry-lab培训更具优势。联合培训模式培训效果优于单一Wet-lab训练(P=0.014)和模拟器培训(P=0.012)，整体满意度高于Wet-lab训练(P=0.042)和Dry-lab培训(P=0.042)。结论：Dry-lab与Wet-lab训练在超声乳化白内障吸除显微手术培训中各有优势，而两者相结合的教学模式更为高效，培训效果更佳，整体满意度高。

Objective: To compare the effects and distinctions among three methods of phacoemulsification training: EYESi simulator (Dry-lab), Wet-lab, and a combined approach, in order to find out more scientific and efficient teaching method. Methods: 18 first-year residents undergoing residency training at Zhongshan Ophthalmic Center, Sun Yatsen University were randomly assigned to three groups: Dry-lab, Wet-lab, and Combined. Each group, consisting of 6 individuals, underwent a specific training regimen—8 sessions of effective simulator training for the Dry-lab group, 8 Wet-lab sessions for the Wet-lab group, and a combination of 4 effective simulator sessions with 4 Wet-lab sessions for the Combined group. The questionnaires were administered to assess simulation effects and student satisfaction before and after each training sessions. Additionally, the training effects were recorded in the three main steps of phacoemulsification cataract extraction surgery on a pig eye model. Results: Both the EYESi simulator and Wet-lab were proved to be effective in facilitating the learning of microscopic instrument use with commendable operating experience. However, Wet-lab is superior to the virtual simulator in terms of stereoscopic sensation (P=0.007), similarity to the human eye (P<0.001), and assistance in mastering techniques(P=0.003). Simulator training is found to be more advantageous in shortening the overall training time (P<0.001). The training effect of the joint training mode is better than that of single Wet-lab training (P=0.014) and simulator training (P=0.012), and the overall satisfaction is higher than that of Wet-lab training (P=0.042) and simulator training (P=0.042). Conclusion: The EYESi virtual surgery simulator and Wet-lab training have their advantages respectively in training for phacoemulsification cataract extraction microsurgery, and the combined teaching mode is more efficient, with better training effects and overall satisfaction.

Objective: To investigate the practical effect of the integrated group cooperation model in managing patients with fundus diseases in day surgery. Methods: 582 patients with fundus disease who underwent day surgery from January to June in 2022 were included as the control group, and 633 patients with fundus disease who underwent day surgery from January to June in 2023 were selected as the study group. The control group implemented the overall responsibility nursing system, while the study group carried out the collaborative management model, integrating medical and nursing for the entire process of patient management. Chi-square test and T-test were used to compare the differences of perioperative nursing knowledge, health education awareness, satisfaction, emergency ophthalmological consultation rate within 24 hours of discharge, follow-up rate within 24 hours of discharge, and nurses' sense of professional benefit between the two groups. Results: The awareness of health education in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–18.47, P<0.05). The satisfaction of patients in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–4.005, P ＜ 0.05). The follow-up rate within 24 hours after discharge was 100% in the study group and 98.1% in the control group, and the difference was statistically significant (χ2=12.073, P<0.05). The incidence of ophthalmic emergencies within 24 hours of discharge in the study group was 0.94%, while in the control group it was 1.89%. There was no statistically significant difference between the two groups (χ2= 1.951, P=0.222). The perceived benefit score of nurses after implementation was higher than that before implementation, and there was statistically significant between two groups (t=–6.637, P<0.05). Conclusions: The medical and nursing integrated group cooperation management model is used to manage the entire perioperative process of patients undergoing day surgery in fundus surgery. This model can improve patients' medical experience, enhance their compliance with ophthalmic surgery, ensure their safety. At the same time, it can enhance the senses of professional benefits for nurses.

Objective: To explore the ocular surface recovery after surgical treatment of strabismus patients. Methods: A total of 92 patients (126 eyes) with strabismus who underwent surgery in our hospital from January 2015 to June 2018 were enrolled. The patients were divided into three groups according to the surgical incision, 42 patients (52 eyes)underwent limbal incision were in group A, 17 patients (19 eyes) underwent trans-muscle end-point incision in group B, and 33 patients (55 eyes) underwent proximal hernia incision in group C. According to the number of muscles involved in the operation, the sick eyes of patients were divided into three groups. The 29 eyes with a single extraocular muscle were a single muscle group, the 42 eyes with 2 extraocular muscles were a double muscle group, and the 21-eye treated with 3 extraocular muscles were a three-muscle group. The ocular surface health recovery time of patients with different incision types and muscle involvement were compared. Results: The first tear film rupture recovery time and tear river height time between group A, B, and C were significantly different,and the data were statistically significant (P<0.05); the first tear film rupture recovery time (14.33±3.26) d and tear river height time (14.54±1.58) d in group A were significantly lower than those in group B and C. The data were statistically significant (F=4.876, P=0.032; F=4.612, P=0.036). The first tear film rupture recovery time and tear river height time between the single, double and three muscle groups were significantly different, and the data were statistically significant (P<0.05); the first tear film rupture recovery time (13.42±3.57) d and tear river height time (8.65±1.62) d were significantly lower in the single muscle group than in the double muscle group and the third muscle group. The data were statistically significant (F=4.975, P=0.028; F=5.024, P=0.025). Conclusion:The number of muscles involved in the operation and the type of surgical incision have an important impact on the health of the ocular surface after surgery. The proximal ankle incision and less number of muscles involved would improve the postoperative recovery of eye health.

目的：探讨高度近视合并白内障患者白内障术后有效晶状体位置的变化。方法：收集白内障超声乳化摘除联合人工晶状体植入术的高度近视合并白内障患者21例共27眼，记录术后1 d、1周、1个月视力、屈光度、有效晶状体位置。结果：高度近视合并白内障患者术后1 d，1周，1个月有效晶状体位置分别为(4.17±0.39)，(4.09±0.38)，(4.31±0.44) mm，且组间比较差异有统计学意义(P<0.05)。有效晶状体位置的实际轴向运动为(0.19±0.13) mm，与晶状体厚度呈正相关(r=0.648，P<0.001)，与术前眼轴无相关关系(r=0.227，P=0.255)。结论：高度近视合并白内障患者术后1 d至1周人工晶状体轻度前移而造成近视偏移，而术后1个月时则呈远视偏移，且术后有效晶状体位置位移与术前晶状体厚度相关。

Objective: To investigate the change and influencing factors of the effective lens position after cataract surgery in high myopia eyes. Methods: We collected 27 eyes of 21 patients with high myopia who underwent phacoemulsification and intraocular lens implantation. The visual acuity, diopter and effective lens position were recorded 1 day, 1 week, and 1 month after operation. Results: The effective lens position of high myopia combined with cataract patients at 1 day, 1 week, and 1 month was (4.17±0.39), (4.09±0.38), and (4.31±0.44)mm, respectively. The effective lens positions significantly differed between the groups after surgery (P<0.05). The ELPRMS was (0.19±0.13) mm. The ELPRMS was positively correlated with the lens thickness (r=0.648,P<0.001), whereas was not correlated with the preoperative axial length (r=0.227, P=0.255). Conclusion: High myopic patients with cataract have a slight forward movement of the effective lens position from 1 day to 1 week after surgery, and a hyperopic shift from 1 week to 1 month. The displacement of effective lens position after surgery is correlated with the preoperative lens thickness.
