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.

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.

Age-related cataract is the leading blinding eye disease in the world, and surgery is the only effective treatment. The good recovery of vision after cataract surgery depends not only on the patients’ ocular conditions but also on the surgical technique and quality management level of medical institutions. Standard surgical procedures, the accurate measurement and calculation of intraocular lens (IOL) power, and professional perioperative management are the keys to restoring the sight of patients. In addition, the National Health Commission proposed in the "Work Plan for Strengthening the Cataract Surgery Capacity Building of County-level Hospitals (2025-2027)" that the ability of county-level hospitals to perform cataract surgery should be further improved by strengthening the construction of equipment and facilities, assisting county-level hospitals in carrying out personnel training, and establishing standardized surgical system. Therefore, in order to standardize cataract surgery procedures, ensure the safety of the surgery and reduce surgical complications, under the leadership of the Guangdong Medical Association, the Zhongshan Ophthalmic Center of Sun Yat-sen University, in conjunction with 21 other medical institutions in Guangdong Province and 35 authoritative experts, jointly drafted this group standard. On the basis of referring to the domestic and international standards for cataract surgery and combining with the current situation of cataract surgery in Guangdong Province, they jointly determined this group standard. This group standard systematically describes the basic requirements for the software and hardware conditions of age-related cataract surgery, the indications and contraindications of the surgery, formulates the standard surgical procedures and quality control standards for cataract surgery, and introduces the prevention and treatment of complications or adverse reactions, providing guidance for all qualified medical institutions at different levels to carry out cataract surgery and quality assessment.

Objective:To investigate the effect of the press-and-chop technique in cataract phacoemulsification training. Methods:From January 2019 to December 2023, 30 trainees who studied cataract phacoemulsification surgery in the ophthalmology department of Guangdong Hospital of Traditional Chinese Medicine,Zhuhai were selected as the research subjects. The training period for all subjects was 3 months, and they were divided into two groups: phaco-chop teaching group and press-and-chop teaching group. The quantity of porcine eye surgeries performed by each trainee before completing the first nuclear chopping, the quantity of porcine eye surgeries performed before completing all surgical steps for the first time, and the number of times of complete nuclear chopping in one attempt were recorded. At the end of the training, the trainees were assessed on their ability to perform porcine eye surgeries and their scores were recorded. A questionnaire survey was conducted to valuate the two teaching methods. Results:The average number of porcine eye surgeries performed by the press-and-chop teaching group before completing the first nuclear chopping was 36.69 (19,50), which was lower than the phaco chop teaching group's 49.86 (29,66);The average number of porcine eye surgeries performed by the press-and-chop teaching group before before the first completion of all surgical steps was 58.13 (31, 79), which was lower than the phaco chop teaching group's 73.14 (50, 90).The average number of complete nuclear chopping in one attempt in the press-and-chop teaching group was 14.75 (9,22), which was higher than the phaco chop teaching group's 6.79 (3,14);The average score of the chopping step of porcine eye surgery for the press-and-chop teaching group was 4.50 (3,5), which was higher than the phaco chop teaching group's 3.71 (2,5);The average score for the press-and-chop teaching group of the complete surgery examination was 29.00 (23, 33), which was higher than the phaco chop teaching group's 23.07 (19, 28).At the end of the training, the average score of the survey questionnaire on the evaluation of teaching effectiveness by the press-and-chop teaching group was 18.31 (15, 20), which was higher than that of the phaco chop, which was 15.07 (12, 18). Conclusions:The press-and-chop technique helps trainees to master the chopping technique faster, shorten the learning curve of cataract phacoemulsification surgery, enhance confidence in learning cataract surgery, and improve the teaching effectiveness and satisfaction of cataract phacoemulsification surgery．

目的：探讨非超声乳化白内障手术两种不同的娩核方式对角膜内皮细胞数量和形态的影响，以及对术后视力恢复情况的影响。

方法：选择在本院手术治疗的40例白内障患者娩核方式分为直接娩出组和半娩出组，并根据 Emery－ little晶状体核硬度分级标准分为软核和硬核，手术方式为白内障非超声乳化手术，术后第3天用角膜内皮镜检查并记录角膜内皮细胞数量和形态。术后随访3个月，比较并观察4组患者术前和术后角膜内皮细胞丢失率、形态变化和视力恢复情况。

结果：术前和术后3个月角膜内皮细胞丢失率比较，硬核直接娩出组与另外三组比较差异有统计学意义(P＜0.01)，而软核直接娩出组、硬核半娩出组与软核半娩出组比较差异无统计学意义(P＞0.05)。术前和术后第二天视力比较硬核半娩出组和软核直接娩出组之间无统计学意义(P＝0.49)，软核半娩出组与这两组比较有统计学意义(P＝0.030)，硬核直接娩出组与这两组之间比较也有统计学意义(P＝0.14)，术后三个月视力比较4组之间均无统计学意义(P＝0.067)。术后 3 个月角膜内皮细胞形态变化不明显。

结论：白内障非超声乳化手术时，硬核直接娩核法对角膜内皮细胞损伤最大，软核半娩核法对角膜内皮损伤最小。若内皮细胞损伤较轻，对手术3个月后视力和角膜内皮细胞形态无明显影响。 

Purpose: To investigate the effect of non-phacoemulsification cataract operation in two different patterns of nucleus delivery on the quantity and morphology of corneal endothelial cells and postoperative visual acuity．

Methods: Forty patients diagnosed with cataract underwent cataract surgery and were assigned into the direct nuclear delivery and semi-nuclear delivery groups. Lens density was measured and divided into the hard and soft lenses according to Emery-little lens nucleus grading system. Non-phacoemulsification cataract operation was performed. At 3 d after surgery, the quantity and morphology of corneal endothelium were counted and observed under corneal endothelial microscope. During 3-month postoperative follow-up, the endothelial cell loss rate, morphological changes and visual acuity were compared among four groups．

Results: Corneal endothelial cell loss rate in the direct delivery of hard nucleus group significantly differed from those in the other three groups before and 3 months after operation (P＜0.01),  whereas no statistical significance was found among the direct delivery of soft nucleus,  semi-delivery of hard nucleus and semi-delivery soft nucleus groups (all P＞0.05).  Preoperative and postoperative 2-d visual acuity did not differ between the semi-delivery of hard nucleus and direct delivery of soft nucleus groups (P＝0.49)，significantly differed from those in the semi-delivery of soft nucleus (P＝0.03) and direct delivery of hard nucleus groups (P＝0.14). Visual acuity at postoperative four months did not differ among four groups (P＝0.067). 
Conclusion: During non-phacoemulsification cataract surgery, direct delivery of hard nucleus caused severe injury to corneal endothelium and semi-delivery of soft nucleus yielded mild corneal endothelial injury. Slight corneal endothelial injury exerted no apparent effect upon visual acuity and corneal endothelial morphology at three months after surgery．

目的：了解表面切削手术前后角膜透明性变化，初步建立角膜光密度与角膜上皮下雾状混浊(Haze)对应的数据库。方法：收集我院行表面切削手术的病人74人146眼。患者手术前、术后3个月行裂隙灯角膜透明性检查和眼前节分析仪(Pentacam，0表示角膜完全透光，100表示角膜混浊不透光)测量角膜光密度。使用SPSS13.0软件对数据进行统计，术前、术后3个月角膜光密度进行Wilcoxon秩和检验；根据裂隙灯下角膜透明性将术后数据分成透明角膜组和Haze组与术前分别对比。术后角膜光密度与裂隙灯下Haze分级进行等级资料Spearman相关分析；按照裂隙灯分级将不同程度Haze与角膜光密度对应，初步建立术后Haze的角膜光密度数据库。结果：术后3个月时，透明角膜(0级Haze)80眼、I级Haze49眼、II级Haze 13眼、III级Haze2 眼、IV级Haze2眼。术前最大 角膜光密度平均值为19.7±2.47，术后3个月时最大角膜光密度平均值为30.3±7.2，术后角膜光密度比术前升高(Z=?7.404，P<0.001)；另外术后Haze组和术后透明角膜组光密度分别为38.2±15.2和21.2±3.51，与术前比两者差异也有统计学意义(Z=?4.783，P<0.001；Z=?5.195，P<0.001)。术后角膜光密度与Haze呈正相关(r=0.819，P<0.001)。各级Haze组对应角膜光密度参考值为I级Haze：29.4±2.58；II级Haze 43.2±5.68；III级Haze：59.5±0.92；IV级Haze: 89.5±14.9。结论：Haze的出现使光密度增加，影响角膜的透明性。手术后裂隙灯观察下的透明角膜光密度较术前高，可能与术后角膜的炎症反应或胶原纤维排列变化有关，需要进一步研究明确。表面切削手术前后角膜的透明性除了传统的裂隙灯检查外，也可以用角膜光密度来评价。用角膜光密度来评价角膜的透明性比单纯的裂隙灯检查更容易发现细微的异常。

Objective: To measure corneal transparency before and after the surface ablation and establish a preliminary database of corneal density and haze. Methods: Seventy-four patients (146 eyes) who underwent surface ablation were measured with the slit lamp and the densitometry program of the Pentacam Scheimpflug imaging system (0=no clouding, 100=tissue completely opaque). The corneal density before and after operation were analyzed with the Wilcoxon’s Matched Pairs Test of the SPSS 13.0. Eyes of 3 months after operation were categorized as postoperative clear corneas and postoperative with haze. According to the slit lamp, different degrees of haze were correlated with corneal density to establish a preliminary corneal density database.Results: At 3 months after operation, there were 80 eyes with clear cornea (grade 0 haze) and 66 eyes with haze which contained 49 eyes with grade I haze, 13 eyes with grade II haze, 2 eyes with grade III haze and 2 eyes with grade IV haze. Maximum density of preoperative corneas was 19.7±2.47, and it was increased to 30.3±7.2 postoperation (Z=?7.404, P<0.001). Maximum density of postoperative clear corneal (21.2±3.51) and postoperative with haze (38.2±15.2) were both higher than preoperation (Z=?5.195, P=0.004 and Z=?4.783, P<0.001). And the haze correlated corneal density was grade I haze 29.4±2.58; grade II Haze 43.2±5.68; grade III haze 59.5±0.92; grade IV haze 89.5±14.9. Conclusion: Corneal density will increase with haze. Maximum density of postoperative clear corneal was higher than preoperation which may be influenced by the postoperative corneal inflammation or the rearrange of collagen ,and it need the further research. Besides the slit lamp, we can use the corneal density to measure the corneal transparency after surface ablation. The densitometry program of the Pentacam can provide a useful objective measure of postoperative and other mild corneal haze.
