人工智能(artificial intelligence，AI)在白内障手术中的应用越来越广泛，二者结合对于白内障手术的术前诊断和分级管理、术中人工晶状体选择、位置预测及术后管理(视力预测、并发症预测及随访)、手术培训和教学方面均起到巨大的促进作用。诚然，AI在与白内障手术相关的管理、分析和研究中还面临着许多问题，但其广泛的应用前景不可忽视。现对AI在白内障手术治疗和教学中的应用做以总结，并对其未来的发展做出展望。
Artificial intelligence (AI) has been widely used in cataract surgery. The combination of the two can play a great role in improving preoperative diagnosis, grading management of cataract surgery, intraoperative intraocular lens selection and location prediction, postoperative management (vision prediction, complication prediction and follow-up), surgical training and teaching. It is true that AI still faces many problems in the management, analysis and research related to cataract surgery, but its broad application prospects cannot be ignored. This review summarizes the application of AI in cataract surgery and teaching, and the future prospects of AI.
传统的眼底手术要求眼科医生具备精细的操作技术，但即便拥有再精湛的操作技术，眼底手术还是存在很大的风险性。因此，为了减少手术风险，提高手术质量，对传统眼底手术进行改进是十分必要的。近年来，在我国对于人工智能产业的大力支持之下，应用于各类行业的机器人随之诞生。机器人辅助系统(robot auxiliary system，RAS)在医学领域，特别是眼科学中应用广泛。对近几年RAS应用于眼底手术的案例进行整理总结，并将RAS参与的眼底手术以及传统的眼底手术进行对比，可以发现RAS在眼底手术中的应用可以显著提高手术效率，并降低手术风险。未来RAS的发展趋势可能着重聚焦于与深度学习算法的紧密结合。通过算法对手术中的视野图像进行预测、优化，从而让高精度的眼底手术更加高效、安全。
Traditional fundus surgery requires ophthalmologists to be equipped with sophisticated operating techniques, but even with the most sophisticated operating techniques, fundus surgery still has great risks. Therefore, in order to reduce the risk of surgery and improve the quality of surgery, it is very necessary to improve the traditional fundus surgery. In recent years, with China’s strong support for the artificial intelligence industry, robots used in various industries have been born. Robot auxiliary system (RAS) is widely used in the medical field, especially in ophthalmology. By summarizing the cases of fundus surgery with RAS in recent years and comparing the fundus surgery involving RAS with traditional fundus surgery, it can be found that the application of RAS in fundus surgery can significantly improve the efficiency of surgery and reduce the risk of surgery. The future development trend of RAS may focus on the close integration with deep learning algorithms, which can predict and optimize the field of view images during surgery so that high-precision fundus surgery can be more efficient and safer.
先天性晶状体不全脱位是一种较为罕见的晶状体悬韧带异常的疾病，其手术治疗极具挑战性。以人工晶状体悬吊为代表的传统手术方式易出现囊袋破裂、玻璃体疝、人工晶状体脱位和继发性青光眼等严重并发症。近年来，以重建囊袋悬韧带隔为目标，新型囊袋辅助装置的应用极大程度提高了先天性晶状体不全脱位的手术成功率。然而，以改良式张力环为代表的囊袋辅助装置在我国仍难以得到普及且操作繁琐。因此，如何最大程度利用普通张力环等最常见的装备，设计出一种安全可靠手治疗先天性晶状体不全脱位的手术方式是眼科界亟待解决的问题。本文将介绍一种二期张力环缝合固定治疗先天性晶状体不全脱位手术技术。该技术仅需使用普通张力环，具有操作简单安全、术后效果稳定和易于技术推广的优点。
Congenital ectopia lentis is a relatively rare zonular disorder of the lens, and its surgical treatment is extremely challenging. The traditional surgical procedures represented by intraocular lens suspension are prone to result in serious complications such as capsular bag rupture, vitreous hernia, intraocular lens dislocation and secondary glaucoma. In recent years, with the goal of reconstructing the capsular bag–zonules diaphragm, the application of new capsular bag-assisted devices has greatly improved the surgical success rate of congenital ectopia lentis. However, the capsular-assisted devices, such as modified capsular tension ring, are still difficult to be popularized in China and the surgical procedures are complicated. Therefore, how to maximize the use of common equipment such as normal capsular tension rings and design a safe and reliable surgical method for the treatment of congenital ectopia lentis is an urgent issue for ophthalmologists. This article aims to introduce a two-stage capsular tension ring fixation for the treatment of congenital ectopia lentis, which has many advantages such as simple and safe operation, stable postoperative effect and less requirements for special equipment, and is worth promoting in clinical practice.
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.
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增大疾病，表现为大角膜(直径≥ 12.5 mm)、前房极深、角膜厚度正常或轻中度变薄和睫状环扩大等。并发性白内障以及晶状体脱位是导致AM视力下降的主要原因。然而，解剖结构的异常使AM白内障手术具有很大的挑战性。文章报道了一例AM合并白内障的48岁男性患者，成功为其行手法小切口白内障摘除联合人工晶状体(intraocular lens, IOL)一期植入术，患者术后视力恢复良好，IOL位置居中，未出现较大的屈光误差。对该典型AM病例的临床特点以及手术难点的回顾总结，有助于加深广大眼科临床工作者对该疾病的认识。
Anterior megalophthalmos is a rare congenital enlargement of the anterior segment, characterized by bilateral nonprogressive megalocornea (diameter ≥12.5 mm), extremely deep anterior chamber, normal or moderate thinning of the cornea, and elongation of the ciliary ring. Cataract and lens dislocation are the main causes of decreased vision in patients with AM. However, cataract surgery on patients with AM are challenging due to the anatomical abnormalities. This case reports a 48-year-old male patient diagnosed with AM and cataract, who successfully underwent a manual small incision cataract extraction combined with intraocular lens implantation. Finally, our patient showed a good visual outcome with a well centered IOL and without obvious refractive error. In this typical AM case, we reviewed and summarized the clinical characteristics and the challenges of surgical treatment so that other ophthalmologists can learn about this disease.

Objective: To analyze the application and testing of non-surgical routine blood test items in clinical diagnosis and treatment in a top-tier ophthalmic hospital over the past five years, providing ophthalmologists with insights into the overview of laboratory-assisted diagnosis, laboratory project management in specialized hospitals, and the basis for launching new projects. Methods: Relevant test records of 22,453 samples (totaling 94,081 test items) from 12,866 outpatient patients who applied for blood tests at the Zhongshan Ophthalmic Center of Sun Yat-sen University from January 1, 2018, to December 31, 2022, were retrieved from the medical laboratory information management system. The departments applying for tests and specialist physicians were divided into 10 subspecialties according to the recommendations of the Ophthalmology Branch of the Chinese Medical Association. Statistical analysis was performed on disease diagnosis and test items, and the results were described in the form of text, bar graphs, and line graphs. Results: Among the 12,866 outpatient patients who applied for blood tests over the five-year period, 6,356 (49.4%) were male and 6,510 (50.6%) were female. Based on the classification of first-visit ophthalmic diseases, the top three were ophthalmic plastic surgery/ocular tumor diseases (5,214 cases, 40.5%), fundus diseases (3,487 cases, 27.1%), and corneal diseases (1,711 cases, 13.3%). The number of samples applied for testing increased from 3,163 in 2018 to 5,903 in 2022, showing an overall upward trend. From the perspective of specialist physicians applying for tests, ophthalmic plastic surgery/orbital disease specialists had the highest number of applications, with 6,751 (30.1%), among which autoimmune disease testing accounted for the highest proportion, at 49.1%, and thyroid disease-related testing accounted for 41.9%. The number of applications from ophthalmic immunology specialists was 4,214 (18.8%), with autoimmune disease testing accounting for 55.7% and infectious disease testing accounting for 32.5%. The number of applications from fundus disease specialists was 3,629 (16.2%), with autoimmune disease testing and infectious disease testing accounting for 47.8% and 39.6%, respectively. The number of applications from corneal disease specialists was 1,436 (6.4%), with allergic disease testing accounting for 41.2%. Since multiple tests could be performed on a single application, the ophthalmic plastic surgery/orbital disease subspecialty had the highest total number of tests applied for, with 33,513 tests, of which thyroid disease testing accounted for 65.0%. The corneal disease subspecialty applied for 16,482 tests, with allergic disease testing accounting for 83.4%. The fundus disease subspecialty and ophthalmic immunology subspecialty respectively applied for 8,794 and 8,047 tests, both primarily focused on autoimmune disease testing, accounting for 42.5% and 40.4%, respectively. Conclusions: The number of applications for non-surgical routine test items in ophthalmic specialized hospitals is significantly unevenly distributed among various subspecialties, and the composition of the items is influenced by the characteristics of diseases in each subspecialty. Ophthalmic laboratories should strengthen the promotion and management of non-surgical routine test items in a targeted manner.

Objective: To evaluate the clinical efficacy of modified “Z”-shaped knotless transscleral suture fixation intraocular lens (IOL) and traditional knotted transscleral suture fixation IOL in congenital ectopia lentis. Methods: A retrospective case study. A total of 73 eyes of 73 patients with congenital ectopia lentis who underwent surgical treatment in our hospital from January 2018 to March 2021 were included. According to different surgical methods, the patients were divided into the knotless group (36 eyes) and knotted group (37 eyes). Preoperative and postoperative of 1-year diopter sphere (DS), diopter cylinder (DC), spherical equivalent (SE), best corrected visual acuity (BCVA), intraocular pressure (IOP), and axial length (AL), corneal endothelial cell counts and the occurrence of postoperative complications rate were analyzed among two groups. Results: There was no significant difference in preoperative outcome measures between the two groups (P>0.05). BCVA at 1-year postoperative was significantly better (P<0.05), and SE at 1-year postoperative was significantly lower (P<0.05). There was no significant difference in BCVA, DS, DC, SE, IOP, AL, and corneal endothelial cell loss rate between the two groups at 1-year after operation (P>0.05). One year after the operation, there were 5 cases of suture exposure (13.5%) in the knotted group and no suture exposure in the knotless group, and the difference was statistically significant (P<0.05). Conclusions: The modified knotless IOL transscleral suture fixation can improve the best corrected visual acuity and alleviate ametropia of CEL patients, and reduce suture exposure and related complications effectively.

Objective: To compare the accuracy of 10 intraocular lens (IOL) power calculation formulas in patients undergoing combined silicone oil removal and cataract surgery, biometry is performed using the swept-source optical coherence tomography biometer OA-2000. Methods: A retrospective analysis. A total of 62 patients (62 eyes) who underwent combined silicone oil removal and cataract surgery in Zhongshan Ophthalmic Center, Sun Yat-sen University from March to July in 2021 were enrolled. Preoperative biometry was performed by OA-2000 in all patients. New-generation formulas (Barrett Universal II [BUII], Emmetropia Verifying Optical [EVO] 2.0, Hill-Radial Basis Function [Hill-RBF] 3.0, Hoffer QST, Kane and Pearl-DGS) and traditional formulas (Haigis, Hoffer Q, Holladay 1 and SRK/T) were evaluated. The median absolute prediction error (MedAE) and mean absolute prediction error (MAE) were the main parameters used to assess accuracy. Subgroup analyses were performed based on the axial length of 23 mm and 26 mm. Results: Six new-generation formulas, Haigis, and SRK/T showed myopic shift (-0.47 ~ -0.27 D, P<0.05), while no systematic bias was found in Hoffer Q and Holladay 1 displayed (P>0.05). The smallest MedAE (0.55 D) and MAE (0.81 D) were found in Kane formula, but there was no statistically significant difference compared with other formulas (P>0.05). The myopic shift (-1.46 ~ -1.25 D, P<0.05) in eyes shorter than 23 mm were found in all formulas, while there was no significant systematic bias (-0.32 ~ 0.41 D, P>0.05) in other subgroups. In axial length shorter than 23 mm, the Pearl-DGS formula stated the smallest MedAE (0.97 D) and MAE (1.26 D), and was significantly more accurate than Hill-RBF 3.0 (P=0.01) and SRK/T (P=0.02). In eyes with an axial length between 23 mm and 26 mm, the Kane formula had the lowest MedAE (0.44 D) and MAE (0.66 D). No significant difference was found in eyes longer than 26 mm. Conclusion: The Kane formula showed the highest accuracy in patients undergoing combined silicone oil removal and cataract surgery measured by OA-2000, whereas the Pearl-DGS formula could be more accurate in eyes with an axial length shorter than 23 mm.
