Objective: To investigate the rationality of perioperative application of non-steroidal anti-inflammatory drugs (NSAIDs) eye drops in patients undergoing cataract surgery, thereby providing evidence for optimizing clinical medication protocols. Methods: A retrospective study method was used to analyse the clinical data of 100 patients (100 eyes) who underwent cataract ultrasonoemulsification with IOL implantation in 2024 at the Second People's Hospital of Zhengzhou City, and the evaluation criteria were developed based on the instructions of the medication, the Chinese expert consensus on prevention and management of non-infectious inflammatory responses in the perioperative period of cataract surgery (2015), the Chinese guideline for cataract surgery in adults (2023), and the Chinese expert consensus on the perioperative medication in laser corneal refractive surgery(2024)" and other guidelines/consensus to develop evaluation criteria to evaluate the standardisation of NSAIDs eye drops in terms of frequency of dosing, duration of treatment, and preoperative prophylactic anti-inflammatory treatment. Results: Irrational medication use was identified in 35% of cases, with a total of 88 issues categorized as follows: incorrect dosage frequency (7.96%), prolonged treatment duration (22.72%), and inappropriate preoperative medication (69.32%). Notably, 65% of diabetic patients failed to initiate NSAIDs pretreatment preoperatively as recommended by guidelines, while 41% of non-diabetic patients received NSAIDs one day before surgery. Prolonged use of bromfenac eye drops (>10 days) was observed in 20.45% of cases, potentially increasing the risk of liver injury. Conclusions: Medical institutions should take active and effective measures, such as formulating individualised medication plans, strengthening training on rational use of medication, and carrying out special prescription reviews, etc., to effectively promote the rational use of NSAIDs eye drops in the perioperative period of patients undergoing cataract surgery, to safeguard the safety of patients' use of medication and therapeutic efficacy, and to improve the quality of healthcare services and patients' satisfaction.

Objective: General anesthesia using laryngeal mask airway (LMA) ventilation can facilitate ambulatory ophthalmic surgery, however, there remains debates about the use of LMA for obese patients. This study retrospectively analyzed the application of LMA in obese patients for ambulatory ophthalmic surgery. Methods: In this retrospective study, we analyzed all patients with a BMI≥25 kg/m2 who underwent ambulatory ophthalmic surgery under general anesthesia at the Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2021 to March 2024.  The patients were divided into two groups: overweight group (BMI 25~<30 kg/m2) and obese group (BMI ≥30 kg/m2) . We compared the changes in hemodynamics and oxygen saturation at the several time points, baseline after entering operating room (T₁), anesthesia induction (T₂), LMA insertion (T₃), start of surgery (T₄), 10 minutes after surgery (T₅), surgery completion (T₆), transfer to PACU (T₇), and LMA removal (T₈);and analyzed the changes in respiratory parameters of the patient at T₃, T₄, T₅, T₆, and T₈ time points between both groups. We also observed the differences in success rate of LMA insertion and ventilation and PACU stay time as well as time to discharge home between two groups. Results: 118 cases were found suitable for the final analysis and divided into overweight group (n=57) and obese group (n=61). All patients in the two groups uneventfully completed the ophthalmic ambulatory surgery and discharged home under the laryngeal mask airway ventilation, none of patients in both group displayed LMA ventilation failure. The hemodynamics and oxygen saturation in both groups were stable during perioperative period(P > 0.05). The peak airway pressures in obese group were dramatically increased than in overweight group at T₃, T₄, T₅, T₆ and T8 time points (P < 0.05), and the incidences of adverse respiratory events in obese group were significant higher than in overweight group （P < 0.05）. The PACU stay time was comparable in both groups (P > 0.05). Conclusion: LMA can be safely used for obese patients undergoing ophthalmic surgery, high BMI is related to high peak airway pressures.

Objective: To investigate the predictive accuracy and effect of capsular tension ring (CTR) implantation with five new generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ), Emmetropia Verifying Optical(EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospective case-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. The patients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group (group B). With the ocular parameters measured by the IOLMaster700, the IOL power was calculated with the BUⅡformula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulas were analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18)mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (P>0.05). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥ 27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.

目的：探讨青光眼日间手术患者的自我管理行为现状及影响因素分析。方法：采用便利抽样法选取2021年9月—2022年5月于广州市某三级甲等眼科专科医院就诊的223例青光眼日间手术患者。采用一般资料调查表、青光眼自我管理行为量表、慢性疾病自我效能量表和青光眼知识学习问卷进行问卷调查。结果：青光眼日间手术患者的自我管理行为得分为(54.03±6.95)分，其中生活调整维度得分最低。慢性病自我效能与自我管理行为呈正相关(r=0.368, P<0.001)。疾病知识与自我管理行为无显著相关性(r=0.077, P=0.252)。多因素线性回归分析结果显示，患者的文化程度(P<0.001)和自我效能(P=0.028)是自我管理行为的影响因素，可解释自我管理行为总变异的12.4%。结论：青光眼日间手术患者具有良好的自我管理行为，较低的自我效能和文化程度是自我管理行为的危险因素，因此应优先提高患者的自我效能，并提供个性化教育。

Objective: To determine self-management and its association with self-efficacy and knowledge among glaucoma patients undergoing day surgery. Methods: A total of 223 glaucoma patients were recruited from September 2021 to May 2022and they were investigated with the Glaucoma Self Management Questionnaire (GSMQ), The Self- Efficacy in Chronic Disease Scale (SECD-6), and the glaucoma knowledge questionnaire. Results: Of the 223 study participants, the study population had a total GSMQ score of 54.03±6.95 with the lowest score found in the life adjustment dimension. The total SECD-6 score was showing a significantly positive correlation with the total GSMQ score(r =0.368, P <0.001). The total score of disease knowledge was without significant correlation with the total GSMQ score (r =0.077, P =0.252). Multivariate linear regression analysis showed that self-efficacy (P <0.001) and education level was independently associated with self-management(P =0.028). Conclusions: Glaucoma patients undergoing daytime surgery demonstrated good overall self-management, yet further improvement was required in terms of life adjustment. Low self-efficacy and educational level were identified as risk factors for self-management. Therefore, self-management programs should prioritize enhancing patients' self-efficacy and delivering individualized education.

慢性肝病（chronic liver disease, CLD）是一种或多种损伤因素长期作用于肝脏导致的疾病总称，其影响范围广、患者人群基数大。病毒性肝炎、非酒精性脂肪性肝病和终末期肝病等慢性肝病会累及眼底，造成视网膜渗出、出血等病变；同时眼底结构改变，如脉络膜和视网膜不同层次厚度，也与慢性肝病严重程度相关。对慢性肝病患者进行眼底检查不仅用于防治相关的眼底并发症，也对肝病临床评估及监测具有潜在应用价值。文章综述不同病因、严重程度和药物治疗下的慢性肝病患者可能出现的眼底病变，以及眼底结构功能检查在慢性肝病患者中的临床应用进展，以比较不同眼底检查方法在慢性肝病患者临床实施过程中的特点及适用场景，并提示未来在慢性肝病患者中应用眼底检查的潜在新方向。

Chronic Liver Disease (CLD) is a collective term for diseases resulting from the long-term effects of one or more damaging factors on the liver. It has a broad impact and affects a large patient population. Viral hepatitis, non-alcoholic fatty liver disease, and end-stage liver disease can involve the ocular fundus, leading to retinal exudates and hemorrhages. Additionally, structural changes in the fundus, such as the thickness of the choroid and different retinal layers, are associated with the severity of chronic liver disease. Through fundus examinations in patients with chronic liver disease, not only can ocular complications related to liver disease be prevented and treated, but these examinations may also offer potential value in the clinical assessment and monitoring of liver disease. This article reviews the potential ocular fundus abnormalities in patients with chronic liver disease under different etiologies, severities, and drug treatments. It discusses the progress in the clinical application of fundus structure and function examinations in patients with chronic liver disease. It compares the characteristics and appropriate clinical scenarios of various fundus examination methods in these patients and suggests potential new directions for the future use of fundus examinations in chronic liver disease management.

目的：探讨白内障人群角膜屈光力(corneal refractive power,CRP)的分布特点及与眼生物学参数的相关因素分析。方法：回顾性横断面研究福州眼科医院2019年3月至2022年7月就诊的40岁以上白内障人群共23035眼，使用OA-2000测量其眼轴(axial length,AL)、CRP、前房深度(anterior chamber depth,ACD)、晶状体厚度(lens thickness,LT)、角膜水平直径即白到白(white-to-white,WTW)、中央角膜厚度(central corneal thickness,CCT)。绘制各眼生物学参数及年龄Spearman相关性热力图，绘制CRP与AL、CRP与WTW散点拟合图。将CRP与上述参数及年龄进行Spearman相关性分析，分段数据的线性关系使用Pearson分析及线性回归分析。结果：白内障人群CRP为(44.36±1.52)D，在总体数据中CRP与AL为非线性相关；但在分段数据中存在线性相关：当AL≤25.06 mm，CRP与AL负线性相关(R² =0.397，P<0.001)；当AL>25.06 mm，CRP与AL正线性相关(R² =0.045，P<0.001)；无论AL长短，CRP与WTW、CCT均呈负相关。在总体数据中，CRP与WTW也存在非线性关系；但在分段数据中存在线性相关：当10.52 mm≤WTW≤12.46 mm，CRP与WTW负线性相关(R² =0.149，P<0.001)，并与AL、ACD、CCT呈负相关。结论：CRP与AL、WTW呈非线性相关，使用CRP优化计算人工晶状体(intraocular lens,IOL)屈光力时需适当考虑AL、WTW与CRP的相关性。

Objective: To investigate the distribution characteristics of corneal refractive power (CRP), and analyze the correlation between corneal refractive power and ocular biometric parameters in cataract patients. Methods: A retrospective cross-sectional study was conducted on 2,3035 eyes of cataract patients over 40 years old, who visited Fuzhou Eye Hospital during the period between March 2019 and July 2022. The subjects' examination results of axial length (AL), corneal refractive power (CRP), anterior chamber depth (ACD), lens thickness (LT), horizontal corneal diameter (WTW), central corneal thickness (CCT) were measured by OA-2000. Spearman correlation thermograms of bilological parameters and age for each eyes were worked out. The plot scatter fitting plots of CRP and AL, CRP and WTW were made. Spearman correlation analysis was made among CRP, above-mentioned parameters and age. Linear relationships of the segmented data were analyzed with Pearson and linear regression analysis. Results: In the cataract patients, CRP was (44.36 ± 1.52) D. There was a non-linear correlation between CRP and AL in the total data. However, there was a linear relationship in the segmented data. When AL ≤ 25.06 mm, CRP was negatively linearly correlated with AL (R² =0.397, P<0.001). When AL>25.06 mm, CRP was weakly positively correlated with AL (R² =0.045, P<0.001). Regardless of the length of AL, CRP was negatively correlated with WTW and CCT. There was also a nonlinear relationship between CRP and WTW in the total data. But there was a linear correlation in the segmented data.When 10.52 mm ≤ WTW ≤ 12.46 mm, the negative linear correlation was found between CRP and WTW (R² =0.149, P<0.001), while there was negative correlation among CRP, AL, ACD, and CCT. Conclusion: There is a non-linear correlation among CRP, AL and WTW. To optimize the calculation of intraocular lens (IOL) refractive power with CRP, it is necessary to consider the correlation between AL, WTW, and CRP.

目的：了解湿性老年性黄斑变性(age-related macular degeneration,AMD)患者自我感受负担(self-perceived burden,SPB)现状及其影响因素。方法：采用方便抽样法选取2021年1月至11月在中山大学中山眼科中心就诊的204例湿性AMD患者为研究对象，采用一般资料调查表、SPB量表、家庭支持自评量表、医学应对问卷对其进行测评。结果：患者SPB得分是(21.98±6.68)分，总体属于轻度SPB。湿性AMD患者的SPB水平与家庭支出(r=?0.326, P<0.001)和面对应对(r=?0.365, P<0.001)呈负相关，与回避(r=0.456, P<0.001)及屈服(r=0.310, P<0.001)应对方式呈正相关性。多重线性回归显示，独居、高龄、自费、双眼患病及采用回避应对的患者的SPB更高，而高文化水平、高家庭支持的患者SPB较轻。结论：湿性AMD患者有轻度SPB，但仍存在改善空间，医护工作者在工作中应重点关注高龄、文化程度低、家庭收入低、自费、独居、双眼患病及低视力的患者，及时进行心理疏导，减轻患者的SPB水平。

Objective: To understand the current status and influencing factors of self-preceived burden (SPB) in patients with wet age-related macular degeneration (AMD). Methods: 204 patiens with wet AMD who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from January to November 2021 were enrolled as the study subjects with convenience sampling method. A general information questionnaire, SPB scale, family support self-assessment scale, and medical coping questionnaire were collected from the subjects for assessment. Results: The patient’s SPB score was 21.98±6.68, which is generally mild SPB. The SPB level of patients with wet AMD was negatively correlated with family support (r=-0.326, P<0.001) and coping (r=?0.365, P<0.001), and were positively correlated with avoidance (r= 0.456,P<0.001), and surrender (r=0.310, P<0.001) coping style. Multiple linear regression showed that the patients who lived alone, were elder and self-funded, had binoclur diseases and used avoidance coping, had higher SPB. While the patients with high education and family support had lower SPB. Conclusions: It is still needed to pay attention to the patients with AMD having mild SPB. Medical workers should focus on patients with elder age, low education level, low family income, self-funded, living alone, binocular disease and low vision in their work, and provide timely psychological counseling to reduce the SPB level of patients.

随着微创玻璃体切除术(pars plana vitrectomy，PPV)的广泛开展和手术技术的提高，患者对手术后视觉质量的要求越来越高。白内障是PPV术后最常见并发症，而具有玻璃体切除史的白内障患者屈光变异大，预测难度高。本文综述了生物测量误差、人工晶状体屈光力计算公式选择以及有效晶状体位置预测等影响有玻璃体切除手术史的白内障患者术后屈光误差的主要因素，旨在为降低这一类特殊人群白内障术后屈光误差提供参考。

With the widespread application of minimally invasive vitrectomy and the improvement of surgical techniques, the demands of patients for better postoperative visual quality are increasing. Cataract is the most common complication after vitrectomy, whereas the refractive outcomes of cataract patients with prior vitrectomy are viable and difficult to predict. In this paper, the main factors affecting postoperative refractive error of cataract patients with a history of vitrectomy, such as biometric error, selection of intraocular lens calculation formulas and prediction of effective lens position, were reviewed in order to provide reference for reducing postoperative refractive error of this special group of cataract patients.
