Objective: To investigate the predictive accuracy and effect of capsular tension ring (CTR) implantation with five new generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ), Emmetropia Verifying Optical(EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospective case-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. The patients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group (group B). With the ocular parameters measured by the IOLMaster700, the IOL power was calculated with the BUⅡformula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulas were analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18)mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (P>0.05). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥ 27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.
目的：探讨白内障人群角膜屈光力(corneal refractive power,CRP)的分布特点及与眼生物学参数的相关因素分析。方法：回顾性横断面研究福州眼科医院2019年3月至2022年7月就诊的40岁以上白内障人群共23035眼，使用OA-2000测量其眼轴(axial length,AL)、CRP、前房深度(anterior chamber depth,ACD)、晶状体厚度(lens thickness,LT)、角膜水平直径即白到白(white-to-white,W T W)、中央角膜厚度(central corneal thickness,CCT)。绘制各眼生物学参数及年龄Spearman相关性热力图，绘制CRP与AL、CRP与WTW散点拟合图。将CRP与上述参数及年龄进行Spearman相关性分析，分段数据的线性关系使用Pearson分析及线性回归分析。结果：白内障人群CRP为(44.36±1.52)D，在总体数据中CRP与AL为非线性相关；但在分段数据中存在线性相关：当AL≤25.06 mm，CRP与AL负线性相关(R2 =0.397，P<0.001)；当AL>25.06 mm，CRP与AL正线性相关(R2 =0.045，P<0.001)；无论AL长短，CRP与WTW、CCT均呈负相关。在总体数据中，CRP与WTW也存在非线性关系；但在分段数据中存在线性相关：当10.52 mm≤WTW≤12.46 mm，CRP与WTW负线性相关(R2 =0.149，P<0.001)，并与AL、ACD、CCT呈负相关。结论：CRP与AL、WTW呈非线性相关，使用CRP优化计算人工晶状体(intraocular lens,IOL)屈光力时需适当考虑AL、WTW与CRP的相关性。
Objective: To investigate the distribution characteristics of corneal refractive power (CRP), and analyze the correlation between corneal refractive power and ocular biometric parameters in cataract patients. Methods: A retrospective cross-sectional study was conducted on 2,3035 eyes of cataract patients over 40 years old, who visited Fuzhou Eye Hospital during the period between March 2019 and July 2022. The subjects' examination results of axial length (AL), corneal refractive power (CRP), anterior chamber depth (ACD), lens thickness (LT), horizontal corneal diameter (WTW), central corneal thickness (CCT) were measured by OA-2000. Spearman correlation thermograms of bilological parameters and age for each eyes were worked out. The plot scatter fitting plots of CRP and AL, CRP and WTW were made. Spearman correlation analysis was made among CRP, above-mentioned parameters and age. Linear relationships of the segmented data were analyzed with Pearson and linear regression analysis. Results: In the cataract patients, CRP was (44.36 ± 1.52) D. There was a non-linear correlation between CRP and AL in the total data. However, there was a linear relationship in the segmented data. When AL ≤ 25.06 mm, CRP was negatively linearly correlated with AL (R2 =0.397, P<0.001). When AL>25.06 mm, CRP was weakly positively correlated with AL (R2 =0.045, P<0.001). Regardless of the length of AL, CRP was negatively correlated with WTW and CCT. There was also a nonlinear relationship between CRP and WTW in the total data. But there was a linear correlation in the segmented data.When 10.52 mm ≤ WTW ≤ 12.46 mm, the negative linear correlation was found between CRP and WTW (R2 =0.149, P<0.001), while there was negative correlation among CRP, AL, ACD, and CCT. Conclusion: There is a non-linear correlation among CRP, AL and WTW. To optimize the calculation of intraocular lens (IOL) refractive power with CRP, it is necessary to consider the correlation between AL, WTW, and CRP.
目的：了解湿性老年性黄斑变性(age-related macular degeneration,AMD)患者自我感受负担(self-perceived burden,SPB)现状及其影响因素。方法：采用方便抽样法选取2021年1月至11月在中山大学中山眼科中心就诊的204例湿性AMD患者为研究对象，采用一般资料调查表、SPB量表、家庭支持自评量表、医学应对问卷对其进行测评。结果：患者SPB得分是(21.98±6.68)分，总体属于轻度SPB。湿性AMD患者的SPB水平与家庭支出(r=?0.326, P<0.001)和面对应对(r=?0.365, P<0.001)呈负相关，与回避(r=0.456, P<0.001)及屈服(r=0.310, P<0.001)应对方式呈正相关性。多重线性回归显示，独居、高龄、自费、双眼患病及采用回避应对的患者的SPB更高，而高文化水平、高家庭支持的患者SPB较轻。结论：湿性AMD患者有轻度SPB，但仍存在改善空间，医护工作者在工作中应重点关注高龄、文化程度低、家庭收入低、自费、独居、双眼患病及低视力的患者，及时进行心理疏导，减轻患者的SPB水平。
Objective: To understand the current status and influencing factors of self-preceived burden (SPB) in patients with wet age-related macular degeneration (AMD). Methods: 204 patiens with wet AMD who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from January to November 2021 were enrolled as the study subjects with convenience sampling method. A general information questionnaire, SPB scale, family support self-assessment scale, and medical coping questionnaire were collected from the subjects for assessment. Results: The patient’s SPB score was 21.98±6.68, which is generally mild SPB. The SPB level of patients with wet AMD was negatively correlated with family support (r=-0.326, P<0.001) and coping (r=?0.365, P<0.001), and were positively correlated with avoidance (r= 0.456,P<0.001), and surrender (r=0.310, P<0.001) coping style. Multiple linear regression showed that the patients who lived alone, were elder and self-funded, had binoclur diseases and used avoidance coping, had higher SPB. While the patients with high education and family support had lower SPB. Conclusions: It is still needed to pay attention to the patients with AMD having mild SPB. Medical workers should focus on patients with elder age, low education level, low family income, self-funded, living alone, binocular disease and low vision in their work, and provide timely psychological counseling to reduce the SPB level of patients.
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.

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.
