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.
人工晶状体混浊是白内障术后较为少见的并发症，患者多于手术后数月或数年因不明原因视力下降或视朦就诊。本文报道一例73岁女性患者，在同一时期双眼先后植入同一型号亲水性丙烯酸酯人工晶状体，术后6年右眼人工晶状体完全混浊，而左眼人工晶状体仍为完全透明状态。两眼的临床眼部体征、眼前节光学相干断层成像(optic coherence tomography,OCT)、超声生物显微镜检查(ultrasound biomicroscopy,UBM)等检查结果均有明显差异，人工晶状体混浊眼通过手术治疗后视力恢复满意。文章详细记录了该例患者术前的相关资料、手术治疗以及手术取出人工晶状体的检查结果，并进行了分析讨论，供专家同行参阅，为该类患者的诊疗提供参考。

Objective: To evaluate the clinical safety and curative effect of phacoemulsification (Phaco) combined with multifocal intraocular lens (MIOLs) implantation in the treatment of senile cataract with 2.2 mm microincision cataract. Methods: The cataract patients who underwent phacoemulsification and intraocular lens implantation in our hospital were selected from January 1, 2018 to June 31, 2018. They were divided into two groups: group A with 31 patients (35 eyes) undergoing 2.2 mm micro-incision Phaco combined with MIOLs, while group B with 31 patients (38 eyes) undergoing 3.0 mm standard incision Phaco combined with single focus IOLs.The preoperative and postoperative uncorrected visual acuity, corneal curvature, intraocular pressure, corneal endothelium number, and defocus curve were recorded in both groups. The parameters during the operation were also recorded and compared. Results: There was no statistically significant difference in the parameters including total phacoemulsification time, total phacoemulsification energy, phacoemulsification cumulative energy compound parameters, effective phacoemulsification time, average phacoemulsification energy, total surgery time between group A and group B during the operation (all P>0.05). Compared with preoperative, the number of corneal endothelial cells decreased both in the two groups after surgery. The difference was statistically significant (P<0.05). There was no significant difference between the two groups at any time (all P>0.05). There were no complications such as posterior capsule rupture during operation in both groups. The corneal astigmatism was increased after operation both in the 2.2 mm incision and 3.0 mm incision, and the difference was statistically significant compared with pre-operation (both P<0.01). There was no significant difference between the two groups (all P>0.05). At 3 months postoperatively, there was no significant difference in uncorrected distance visual acuity (UCDVA) between the two groups (t=?1.794, P=0.07), and the difference was statistically significant in the uncorrected near visual acuity (UCNVA) (t=?25.147, P<0.01). Defocus curve: The defocus curve of group A had two peaks, which are located near 0 D and ?3.5 D, forming a flat platform with a descent between the two peaks.The defocus curve of group B had only one peak, located at 0–0.5 D, and the downward trend at both ends of the peak was obvious. The rate of off-glasses and satisfaction: the rate of off-glasses in group A was 77.42% (24/31),and the rate of dislocation in group B was 12.90% (4/31). The difference was statistically significant (χ2 =26.050,P<0.01). There was no significant difference in overall satisfaction between the two groups (χ2 =1.615, P=0.204).Conclusion: The 2.2 mm coaxial microincision cataract surgery yields high clinical safety, and the combined implantation of multi-focal intraocular lens has good curative effect and can be widely promoted in clinical practice.
白内障是世界范围内失明的主要原因。正常晶状体是富有弹性的形似双凸透镜的透明体，是机体内蛋白质含量最高的组织，由晶状体囊膜、晶状体上皮细胞、晶状体纤维和悬韧带构成。白内障为晶状体透明度下降，表现为晶状体混浊。近年来随着分子生物学、表观遗传学、免疫学、有机化学等学科快速发展，国内外学者对白内障也进行了大量分子水平的研究，探讨了白内障发生发展相关分子机制，为未来基因治疗和靶向药物等治疗白内障提供了理论基础。对白内障分子病理改变的了解，是白内障精准诊治的基础。
Cataract is the main cause of blindness worldwide. The normal crystalline lens is a transparent biconvex disc,with highest protein content in all human tissues. The lens is composed of capsule, lens epithelial cells, lens fiber and zonular ligment. Cataract is a decrease in the transparency of the lens, which is characterized by opacity. In recent years, with the rapid development of molecular biology, epigenetics, immunology and organic chemistry,researchers have conducted a large number of studies on the molecular basis of genetic or targeted therapy of cataract. It is important to know the molecular pathology of cataract, which is the basis of precise diagnosis and treatment of cataract.

Objective: To compare the consistency of Kappa Angle measurements in patients with age-related cataracts using four instruments of different principles in a dark room. Methods: Sixty cases (60 eyes) of age-related cataract were adapted in the darkroom for 10 minutes. The pupil size and angle Kappa were measured by iTrace, Pentacam HR, Lenstar900 and IOLMaster700. One-way ANOVA test and Kruskal-Wallis nonparametric test were used to compare the measured data among the four instruments, and Bland-Altman analysis was used for consistency comparison. Results: The measured pupil diameters of iTrace, Pentacam HR, Lenstar900 and IOLmaster700 were 4.64±0.71 mm, 2.96±0.47 mm, 4.86±0.76 mm and 4.66±0.92 mm. The Angle Kappa sizes were 0.227±0.121 mm, 0.161± 0.09 mm, 0.2±0.124 mm, 0.203±0.104 mm. The proportion of angle Kappa larger than 0.5 mm was 3.33%, 3.33%, 1.67% and 1.67%. The measurement results of angle Kappa between Pentacam and iTrace were statistically significant (P=0.001). There was no significant difference in the measurement results of angle Kappa between Pentacam and Lenstar900, Pentacam HR and IOL-Master700 (P=0.044, 0.036). There was no significant difference in the results of angle Kappa measurement among the other three instruments. The subjective score of light intensity in the process of measurement of iTrace, Pentacam HR, Lenstar900 and IOLMaster700 showed that during the process of measurement, 60 cases (100%) experienced obvious discomfort caused by the light intensity in Pentacam HR, while 40 cases (66.67%) felt comfort in IOLMaster700. The differences among the subjective score of light intensity of four instruments were statistically significant (P<0.001). Conclusion: The consistency of the measurement results of Kappa angle between Pentacam HR and iTrace, Lenstar900, IOLMaster700 in the darkroom is relatively poor, so it is necessary to be careful to replace them in clinic.

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.
