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.

目的：通过对改良“Z”形无线结经巩膜缝线固定人工晶状体手术和传统有线结巩膜缝线固定人工晶状体手术治疗先天性晶状体脱位的比较来评价改良术式的临床疗效。方法：回顾性病例研究。纳入2018年1月—2021年3月期间于中山大学中山眼科中心行手术治疗的先天性晶状体脱位患者73例73眼，按手术方式不同将患者分为无线结组36例36眼和有线结组37例37眼。比较两组患者术前和术后1年的球镜度(DS)、柱镜度(DC)、等效球镜(SE)、最佳矫正视力(BCVA)、眼压(IOP)、眼轴长度(AL)、角膜内皮细胞计数和术后并发症的发生率。结果：两组患者术前各项观察指标组间比较差异无统计学意义(均P>0.05)。两组患者术后1年 BCVA 均较术前提高(均P<0.05)，SE均较术前降低(均P<0.05)。两组患者术后1年 BCVA 、DS、DC、SE、IOP、AL、角膜内皮细胞丢失率组间比较差异均无统计学意义(均P>0.05)。术后1年，有线结组有5例(13.5%)出现缝线暴露，无线结组未出现缝线暴露，组间比较差异有统计学意义(P<0.05)。结论：改良无线结 IOL 巩膜缝线固定手术可改善CEL患者的最佳矫正视力和屈光不正，有效减少缝线暴露及相关并发症。

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.

目的：探索斜视患者手术治疗后的眼表恢复状况。方法：选取2015年1月至2018年6月于如皋市广慈医院接受门诊手术治疗的92例水平性斜视患者为研究对象，共126眼，按照手术切口将患者分为3组，行角膜缘切口的42例52眼患者为A组，行跨肌止端切口的17例19眼患者为B组，行近穹窿切口的33例55眼患者为C组。再根据手术累及肌肉条数将患眼分为3组，行单条眼外肌的29眼手术者为单肌组，行2条眼外肌的42眼手术者为双肌组，行3条眼外肌的21眼手术者为三肌组。比较不同切口类型和肌肉累及数患者的眼表健康恢复时间。结果：A，B，C3组间首次泪膜破裂恢复时间、泪河高度时间差异有统计学意义(P<0.05)；A组首次泪膜破裂恢复时间(14.33±3.26) d和泪河高度时间(14.54±1.58) d显著低于B组和C组，差异具有统计学意义(F=4.876，P=0.032；F=4.612，P=0.036)。单肌组，双肌组及三肌组3组间首次泪膜破裂恢复时间、泪河高度时间差异有统计学意义(P<0.05)；单肌组的首次泪膜破裂恢复时间(13.42±3.57) d和泪河高度时间(8.65±1.62) d显著低于双肌组和三肌组，差异有统计学意义(F=4.975，P=0.028；F=5.024，P=0.025)。结论：手术累及的肌肉数和手术切口类型对术后眼表健康状况具有重要影响，近穹窿切口的手术方式和累及较少肌肉数量有助于患者术后眼部健康状况的恢复。

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：评价上睑下垂矫正术后并发上睑内翻倒睫的手术治疗效果，并分析其发生原因。方法：回顾性分析2015年1月1日至2020年6月30日因上睑下垂矫正术后并发上睑内翻倒睫在中山大学中山眼科中心接受手术治疗，随访时间6个月以上的患者资料。患者的内翻倒睫矫正手术方案根据有无合并上睑下垂过矫或者欠矫，以及原上睑下垂矫正的矫正方式进行设计。评价术前、术后患者的睑裂高度、眼睑闭合不全程度、上睑睑缘弧度、内翻倒睫矫正状态和角膜荧光素染色评分。结果：本研究共收录上睑下垂术后并发上睑内翻倒睫患者19例(20眼)，其中额肌肌瓣悬吊术后17例(18眼：上睑过矫8眼，欠矫6眼，睑裂高度正常4眼)，提上睑肌缩短术后2例(2眼：上睑过矫1例，欠矫1例)。所有患者的上睑内翻倒睫经手术治疗均完全矫正，角膜上皮荧光素染色评分显著降低(P<0.05)。上睑下垂过矫或欠矫术后均矫正满意，术前睑裂高度正常的患者矫正内翻倒睫没有改变睑裂高度。总结术中探查所见，上睑下垂矫正术后发生上睑内翻倒睫可能与多个因素相关：上睑皮肤切口位置过低；睑缘眼轮匝肌去除过多；额肌肌瓣分离不佳；额肌肌瓣在睑板上的固定位置过高；术中对睑裂高度评估不准确引起上睑下垂过矫等。结论：上睑下垂矫正术后并发上睑内翻倒睫再次手术可以达到满意的治疗效果，但手术操作较为棘手。为降低此类并发症的发生和患者多次手术的风险，应规范上睑下垂矫正手术操作，总结教训。

Objective: To evaluate the surgical treatment outcome of upper eyelid entropion after ptosis correction and analyze the complicated causes. Methods: A retrospective analysis was performed on patients who underwent surgical treatment for complicated upper eyelid entropion after ptosis correction and were followed up for more than 6 months at Zhongshan Ophthalmic Center from January 1, 2015 to June 30, 2020. Pre- and postoperative lid height, lagophthalmos, upper lid margin curvature, eyelid entropion and corneal fluorescein staining scores

were evaluated. Results: A total of 18 cases (19 eyes) were included, among which 17 cases (18 eyes: 8 eyes of ptosis overcorrection, 6 eyes of ptosis undercorrection, and 4 eyes with normal eyelid height) were post-frontalis flap suspension, and 2 cases (2 eyes: 1 eye of ptosis undercorrection, 1 eye of ptosis overcorrection) post-levator resection. All patients had a complete correction of upper eyelid entropion and a significant reduction in corneal epithelial fluorescein staining score (P<0.05). Both the complicated ptosis undercorrection and overcorrection were treated with satisfactory outcome. Correction of entropion did not change the eyelid height in patients with preoperative normal height. The intraoperative findings showed that several factors related to original ptosis surgery may be involved in complicated upper eyelid entropion, including: the skin incision too close to the upper lid margin, excessive resection of the orbicularis oculi muscle along the eyelid margin, poor separation of the frontalis muscle flap, inappropriate eyelid plate fixation site of the frontalis muscle flap, and ptosis overcorrection caused by inaccurate evaluation of the intraoperative eyelid height, etc. Conclusion: Surgical treatment of the upper eyelid entropion secondary to ptosis correction is safe and effective, but is complicated and difficult. Skillful ptosis surgery and appropriate surgical techniques are crucial to reduce its occurrence.
