该文报道了一例40岁女性患者，因“双眼渐进性视物模糊3个月”就诊。患者既往于2005年因高度近视行双眼准分子激光原位角膜磨镶术 (LASIK)。最佳矫正视力OD：0.2 (–11.00 DS/ –1.25 DC×170 °)，OS：0.7 (–4.00 DS/ –0.75 DC×25 °)。双眼角膜透明，前房中深，晶状体混浊，豹纹状眼底伴后巩膜葡萄肿。诊断为双眼并发性白内障，并行右眼白内障超声乳化联合人工晶状体 (IOL) 植入术，术中植入+14.0 D IOL一枚，目标屈光度为–0.5 D。术后1周裸眼视力0.3，验光结果示右眼屈光度+2.75 DS，最佳矫正视力0.7。术后2周行右眼IOL置换术，由+14.0 D置换为+17.0 D。右眼术后1周裸眼视力0.8，验光结果示右眼屈光度–0.75 DC×15 °。
It is reported in this article that a 40-year-old female patient presented with "progressive blurred vision of both eyes for 3 months". The patient underwent bilateral laser in situ keratomileusis (LASIK) because of high myopia in 2005. It was recorded that her best corrected visual acuity was 0.2 (–11.00 DS/ –1.25 DC×170 °) in the right eye and 0.7 (–4.00 DS/ –0.75 DC×25 °) in the left, and clear cornea, normal anterior chamber, cloudy lens, tessellated fundus with posterior staphyloma in both eyes. The patient was diagnosed with bilateral complicated cataract. Phacoemulsification combined with intraocular lens (IOL, +14.0 diopter (D)) implantation was performed on the right eye, with the target –0.5D refractive diopter . One week after surgery, it was recorded that the uncorrected visual acuity of the right eye was 0.3, and the best corrected visual acuity was 0.7 (+2.75 DS). IOL replacement of the right eye was performed two weeks after surgery, the +14.0 D IOL was replaced by +17.0 D IOL. One week after surgery, the uncorrected visual acuity of the right eye was 0.8 (–0.75 DC×15 °).
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.
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.
目的：比较四种不同原理的仪器在暗室中对年龄相关性白内障患者Kappa角测量的一致性。方法：对年龄相关性白内障术前60例(60只眼)，暗室中适应10 min后，分别应用iTrace视觉分析仪、Pentacam HR、Lenstar900、IOLMaster700测量瞳孔直径和Kappa角。四种仪器间所测量的数据比较采用单因素方差分析检验和Kruskal-Wallis非参数检验，一致性比较采用Bland-Altman分析。结果：iTrace、Pentacam HR、Lenstar900、IOLMaster700测量瞳孔直径分别为(4.64±0.71) mm，(2.96±0.47) mm，(4.86±0.76) mm，(4.66±0.92) mm；Kappa角大小分别为(0.227±0.121) mm，(0.161±0.09) mm，(0.2±0.124) mm，(0.203±0.104) mm；大于0.5 mm的Kappa角比例分比为3.33%、3.33%、1.67%、1.67%；Pentacam和iTrace的Kappa角测量结果有统计学意义(P=0.001)，Pentacam和Lenstar900、IOLMaster700的Kappa角测量结果差异无统计学意义(P=0.044，0.036)，其他三种仪器之间Kappa角测量结果差异均无统计学意义(P=0.181，0.245，0.860)； 60例被检测者对iTrace、PentacamHR、Lenstar900、IOLMaster700四种仪器测量过程中光强度主观评分结果显示60例(100%)被检测者认为Pentacam HR在测量过程中有明显的不适感，40例(66.67%)被检测者认为IOLMaster700检测过程中舒适感最好，结果差异有统计学意义(χ2=191.236，P<0.001)。结论：Pentacam HR与iTrace、Lenstar900和IOLMaster700三种仪器在暗室中Kappa角的测量结果一致性稍差，临床上需谨慎替换使用。
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.

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.
