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.

Objective: To investigate the effect of corneal bandage lens on anxiety and quality of life in patients with monocular cataract. Methods: A total of 120 patients with monocular cataract treated in our department from December 2020 to July 2021 were selected as the subjects. They were divided into an experimental group (wearing corneal bandage lens) and a control group (without corneal bandage lens) by convenient sampling method. Self-rating Anxiety Scale and Visual Function Quality of Life Scale were used to evaluate and compare the degree of anxiety and postoperative quality of life between the 2 groups. Results: There was no significant difference in anxiety score and quality of life score between the 2 groups before admission (P>0.05). On the first day after operation, the anxiety score of the experimental group was significantly lower than that of the control group, and the quality of life score was significantly higher than that of the control group (P<0.05). The anxiety score of patients in the experimental group decreased from 55.35±7.09 to 43.77±5.56, and the degree of anxiety decreased by 20% compared with that before admission. The anxiety score of patients in the control group decreased from 54.27±5.93 to 47.92±7.02, and the degree of anxiety decreased by 12% compared with that before admission. The score of quality of life in the experimental group increased from 55.32±25.57 before admission to 81.01±13.74 on the first day after operation, an increase of 46%. The quality of life score of patients in the control group decreased from 56.38±14.43 before admission to 36.15±17.97 on the first day after operation, a decrease of 35%.Conclusion: Corneal bandage lens can reduce the anxiety of patients with monocular cataract and improve the quality of life after operation.

Objective: The aim of this study is to observe the efficacy and safety of propofol-alfentanil-lidocaine mixture in adult patients for cataract ambulatory surgery. Methods: Thirty adult patients undergoing cataract ambulatory surgery sedated by propofol-alfentanil-lidocaine mixture from January 2021 to June 2021 were enrolled in this retrospective study (sedation group, n=30). Meanwhile, another thirty patients with similar diagnosis performed by the same surgeons under topical anesthesia were matched in this study (topical anesthesia group, n=30). The scores of intraoperative eye position, the number of surgical interruptions due to poor cooperation, surgical time, emergence time, time to discharge, changes in blood pressure, surgical experience, as well as any adverse events were compared between the two groups. Results: The surgeries were successfully completed in all patients in both groups. Compared to topical anesthesia group, patients under sedation showed less surgical interruptions and more stable hemodynamics during the surgery, as well as better surgical experience (all P<0.05). Conclusion: Sedation with propofol-alfentanil-lidocaine mixture can significantly improve the surgical experience of patients undergoing cataract ambulatory surgery without prolonging duration of the surgery.

囊袋阻滞综合征(capsular block syndrome，CBS)是白内障手术较为罕见的并发症，可发生在白内障术中、术后早期及晚期。本文报道1例23岁的女性患者，为发生在白内障术后早期的CBS，因左眼激素性白内障而实施左眼白内障超声乳化联合后房型人工晶状体(intraocular lens，IOL)植入术，术后患者因屈光不正、后囊膜及IOL之间较宽间隙而诊断为CBS，行Nd:YAG激光后囊膜切开治疗后，患者视力恢复至正常，后囊膜及IOL贴合紧密，随访期间未出现黄斑水肿及视网膜脱离等并发症。

Capsular block syndrome (CBS), a fairly rare complication of phacoemulsification, can develop into one of the three following possible clinical scenarios: intraoperative, early postoperative, and late postoperative, depending primarily on the timing of its occurrence following surgery. This paper reported a patient who developed early capsular block syndrome. A 23-year-old patient complained of poor distant vision after undergoing phacoemulsification combined with intraocular lens (IOL) implantation because of steroid-induced cataract. Anterior segment examination confirmed the diagnosis of capsular block syndrome. Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy resulted in complete resolution of her symptoms. No complication happened during follow-up.

Objective: To explore the causes of low vision after cataract surgery. Methods: Patients who underwent cataract surgery at Joint Shantou International Eye Center of Shantou University and the Chinese university of Hong Kong ( JSIEC) from October 2011 to March 2013, whose fundus status could not be seen before surgery, and the best corrected visual acuity <0.3 in the first week after surgery, underwent a series of detailed ocular examinations, including visual acuity, best corrected visual acuity, intraocular pressure, slit-lamp examination, fundus examination, fundus photography and optical coherence tomography. If no organic lesions of the retina were found, then visual evoked potential examination and visual field examination were performed. Two doctors analyzed the examination results of the examination, made the diagnosis of different fundus diseases, and statistically analyzed the causes of low vision after cataract surgery. Results: A total of 5 608 cataract surgeries were performed in our hospital from October 2011 to March 2013. A total of 49 patients (49 eyes) with best corrected visual acuity worse than 0.3 within postoperative 1 week 20 male and 29 female, 31 right eyes and 18 left eyes, aged (69.11±12.05) years on average. The proportion of low vision after cataract surgery was 0.87%. 12 cases (24.5%) of high myopic chorioretinopathy, 10 cases (20.4%) of ellipsoidal band defect, 8 cases (16.3%) of diabetic retinopathy, 5 cases (10.2%) of macular holes, 4 cases (8.1%) of age-related macular degeneration, 3 cases (6.1%) of macular epiretinal membrane, 1 case (2.0%) of thinning macular retinal thickness, 1 case (2.0%) of retinitis pigmentosa, 1 case of retinoschisis (2.0%), 1 case of branch retinal artery occlusion (2.0%), 1 case of Behcet’s disease (2.0%), and 1 case of ischemic optic neuropathy (2.0%), 1 case of epiretinal membrane (2.0%). Conclusion: Among patients with low vision after cataract surgery, high myopic chorioretinopathy accounts for 24.5%, followed by ellipsoidal band defect, diabetic retinopathy, macular hole, age-related macular degeneration, and macular epiretinal membrane. The use of optical coherence tomography can detect subtle microscopic retinal structural changes that affect vision after cataract surgery. For patients with visible fundus before cataract surgery, routine optical coherence tomography contributes to evaluating the prognosis of the operation, facilitating doctorpatient communication, and improving the degree of surgical satisfaction.

Objective: To explore the application of children’s binocular vision screening instrument in screening congenital cataract. Methods: This was a retrospective analysis of 336 infants aged 3 months to 2 years (672 eyes) who were admitted to the Ophthalmology Department of Xiamen Children's Hospital from July 2017 to May 2018. They were examined by two fixed doctors with the pupil red light reflex and binocular vision screening instrument, and the medical history was recorded in details. All the children received slit lamp examination, compound tropicamide mydriasis and fundus examination. If necessary, the children who could not see fundus were given with B-ultrasonic examination or MRI examination. Results: According to the clinical classification of congenital cataracts published in the 5th edition of Harley’s pediatric ophthalmology in 2009, In this group, there were 27 cases (35 eyes) of congenital cataract, including 2 cases (4 eyes) of embryonic nucleus, 23 cases (29 eyes) of lamellar layer, 2 cases (2 eyes) of nuclear cataract, 19 cases (28 eyes) of capsular cataract, 2 cases (4 eyes) of suture cataract, 3 cases (6 eyes) of polar cataract and 2 cases (3 eyes) of total cataract. The sensitivity of children’s binocular vision screening instrument screening congenital cataract was 81.58%, the specificity was 79.87%, and the diagnostic coincidence rate was 80.06%; the sensitivity of red reflection screening congenital cataract was 51.32%, the specificity was 69.97%, and the diagnostic coincidence rate was 67.86%; the results of the two groups were statistically significant. The screening rate of children's binocular vision screening instrument for cortical (nuclear) cataract was 97.14%, while that of red reflex was 37.14%. The results were statistically significant. Conclusion: In the screening of congenital cataract, the binocular vision screening instrument for children has the advantages of low missed diagnosis rate, high misdiagnosis rate and high diagnostic consistency, especially for cortical (nuclear) cataract. It is helpful to find the congenital cataract early in the auxiliary screening of children’cares eye health
