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.

A 42 year-old female patient who underwent bilateral LASIK surgery in other hospital 20 years ago. She visited our hospital due to blurred vision in her right eye for one year. The preoperative IOL Master examination results showed an axial length of 29.66 mm, anterior chamber depth of 3.18 mm, lens thickness of 4.75 mm, white to white distance of 11.6 mm, and anterior surface and total corneal astigmatism of 1.01 D @ 67 ° and 0.91 D @ 56 °, respectively in right eye. The corneal astigmatism measured by Pentacam using 15°range simulated keratometry is 1.2 D@ 58.1 °, which is a regular bow tie shape.No obvious abnormalities was found in the patient's fundus examination. Due to her strong desire to get rid of the glassesa toric bifocal IOL (AT LISA Toric 909M, Zeiss, Germany) was implanted.Based onthe IOL power calculation results of Barrett True-K Toric formula with measured posterior corneal astigmatism, an IOL with Sph 17.0 D/Cyl1.5 D/A 55°was chosen. One month after surgery, the patient's uncorrected distance visual acuity was 20/25, 35 cm uncorrected near visual acuity was 20/20, and the best corrected distance visual acuity was 20/20 with a prescription of –0.25 DS/–0.5 DC × 120 °. The patient was satisfied with the outcome. After detailed preoperative evaluation and design, and sufficient communication with patients, toric multifocal IOL implantation can achieve good results in some apropriated for the patients after LASIK surgery.
目的：探讨超声乳化晶状体吸除联合囊袋上经巩膜缝线固定人工晶状体(intraocular lens,IOL)植入术治疗球形晶状体(microspherophakia,MSP)的有效性和安全性。方法：采用回顾性分析，选取2019年1月至 2020年6月期间在复旦大学附属眼耳鼻喉科医院进行治疗的MSP患者37例(37眼)，随机分为两组，纳入行超声乳化晶状体吸除联合囊袋上巩膜缝线固定IOL植入术(supra-capsular and scleral-fixated intraocular lens implantation,SCSF-IOL)的MSP患者20例(20眼)和行超声乳化晶状体吸除联合改良型囊袋张力环植入术(transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation,MCTR-IOL)的MSP患者17例(17眼)，观察两组术后最佳矫正视力及并发症等情况。结果：两组术后最佳矫正视力比术前均有改善(P<0.001)，而组间比较差异无统计学意义(P=0.326)。两组的IOL倾斜度相当(P=0.216)。预防性Nd:YAG激光后囊膜切开术在SCSFIOL术后1周至1个月进行。在SCSF-IOL组，2眼(10.00%)需要重复激光治疗，1眼(5.00%)出现囊口偏心。后囊膜混浊是MCTR组最常见并发症(6眼,35.29%)。随访期间两组均未出现IOL脱位、继发性青光眼和视网膜脱离。结论：SCSF-IOL是治疗球形晶状体的简单易行的手术方式，疗效与MCTR-IOL相当。Nd:YAG激光后囊膜切开术是预防SCSF-IOL术后囊袋并发症的必要手段。
Objective: To investigate the efficacy and safety of phacoemulsification combined with supra-capsular and scleral-fixated intraocular lens (IOL) implantation in the treatment of microspherophakia (MSP). Methods: by retrospective analysis, 37 MSP patients (37 eyes) who were treated in our hospital from January 2019 to June 2020 were randomly divided into two groups, including 20 MSP patients (20 eyes) who treated by SCSF-IOL and 17 MSP patients (17 eyes) who treated by transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation (MCTR-IOL). The best corrected vision and complications were observed. Results: the best corrected vision was significantly improved in both groups (P < 0.001), but there was no remarkable difference between the two groups (P = 0.326). The IOL tilt was also comparable (P = 0.216). Prophylactic Nd: YAG laser posterior capsulotomy was performed from 1 week to 1 month after the SCSF-IOL procedure. In the SCSF-IOL group, two eyes (10.00%) needed repeated laser treatment, and one eye (5.00%) had a decentered capsule opening. Posterior capsular opacification was the most common complication (6, 35.29%) in the MCTR group. No IOL dislocation, secondary glaucoma, or retinal detachment was observed during follow-up. Conclusions: SCSF-IOL is a simple and viable surgical option for managing MSP and is comparable with the MCTR-IOL. Nd: YAG laser posterior capsulotomy is a necessary mean to prevent residual capsule complications after the SCSF-IOL procedure.

Aims: To establish and evaluate predictive models for glaucoma-related adverse events (GRAEs) following secondary intraocular lens (IOL) implantation in paediatric eyes. Methods: 205 children (356 aphakic eyes) receiving secondary IOL implantation at Zhongshan Ophthalmic Center with a 3-year follow-up were enrolled. Cox proportional hazard model was used to identify predictors of GRAEs and developed nomograms. Model performance was evaluated with time-dependent receiver operating characteristic (ROC) curves, decision curve analysis, Kaplan-Meier curves and validated internally through C-statistics and calibration plot of the bootstrap samples. Results: Older age at secondary IOL implantation (HR=1.5, 95% CI: 1.03 to 2.19), transient intraocular hypertension (HR=9.06, 95% CI: 2.97 to 27.67) and ciliary sulcus implantation (HR=14.55, 95% CI: 2.11 to 100.57) were identified as risk factors for GRAEs (all p<0.05). Two nomograms were established. At postoperatively 1, 2 and 3 years, model 1 achieved area under the ROC curves (AUCs) of 0.747 (95% CI: 0.776 to 0.935), 0.765 (95% CI: 0.804 to 0.936) and 0.748 (95% CI: 0.736 to 0.918), and the AUCs of model 2 were 0.881 (95% CI: 0.836 to 0.926), 0.895 (95% CI: 0.852 to 0.938) and 0.848 (95% CI: 0.752 to 0.945). Both models demonstrated fine clinical net benefit and performance in the interval validation. The Kaplan-Meier curves showing two distinct risk groups were well discriminated and robust in both models. An online risk calculator was constructed. Conclusions: Two nomograms could sensitively and accurately identify children at high risk of GRAEs after secondary IOL implantation to help early identification and timely intervention.

Objective: To assess the efficacy and safety of phakic refractive lens (PRL) implantation for the correction of ultra-high myopia. Methods: This self-controlled case series study included 39 eyes of 24 patients with ultra-high myopia who underwent PRL implantation at Shenzhen Eye Hospital between January 2018 and September 2020. The study comprised 13 eyes in 8 males and 26 eyes in 16 females, with a mean age of (31.15 ± 6.33) years. Postoperative parameters, including refraction, visual acuity (UCVA, BCVA), intraocular pressure, corneal endothelial cell count,vault, and surgical complication were observed. Results: The median follow-up time was 5.5 (3, 11) months. The refraction significantly decreased from preoperative (-22.29±4.96) D to postoperative (-0.28±1.01) D (t=24.421, P<0.001). Postoperatively, 82.4% of eyes achieved a spherical degree within ±0.5 D, and 91.2% within ±1.0 D. LogMAR UCVA significantly improved from 1.40 (1.30, 1.70) preoperatively to (0.28±0.20) postoperatively. LogMAR BCVA significantly improved from 0.40 (0.22, 0.70) preoperatively to 0.15 (0.00, 0.30) postoperatively (P<0.001 for all). Postoperative BCVA improved by 3.00 (1.00, 5.00) lines compared with preoperative BCVA, with no instances of BCVA loss in any patient. Intraocular pressure values showed significant differences among preoperative, 1 day postoperative and last follow up (F=8.779, P=0.012). Intraocular pressure increased significantly 1 day after surgery compared to before surgery (Z=-3.401, P=0.001), but decreased significantly at the last follow-up compared to 1 day postoperatively(Z=-2.685, P=0.007), with no significant difference in intraocular pressure between preoperative and last follow-up (Z=-0.894, P=0.371). Corneal endothelial cell count decreased significantly from preoperative (2 782.20±296.30)/mm2 to postoperative (2 472.54±394.32)/mm2 (t=?5.437, P<0.001), with a mean loss of 11.2%. The average vault at the last follow-up was (379.00±283.27) μm, of which 0~250 μm in 12 eyes (36.4%), 250~750 μm in 19 eyes (57.6%), and > 750 μm in 2 eyes (6%). In 21 eyes, the vault at 3 months postoperative (269.81±194.67) μm was significantly lower than that at 1 month postoperative (373.62±195.75) μm (t=?2.917, P=0.009). Postoperative complications included steroid-induced glaucoma (2 eyes in 1 case), PRL optical surface crack (1 eye), macular hemorrhage (1 eye), and PRL decentration (3 eyes in 2 cases). Conclusions: PRL implantation is a safe and effective intraocular refractive surgery for ultra-high myopic patients. Nonetheless, it should be neccessary to observe for long-term efficacy and saff lens; high myopia

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.
