It is reported a case of cataract phacoemulsification combined with toric multifocal intraocular lens (IOL) implantation after LASIK surgery in this article. 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.

目的：分析高度近视有晶状体眼后房型人工晶状体植入术后孔源性视网膜脱离的临床特征及预后。方法：回顾分析2012年4月至2021年6月中山眼科中心收治的9例(9只眼)行后房型人工晶状体植入术后孔源性视网膜脱离患者的临床特征、手术方式及疗效，随访(4.96±4.78)个月。结果：患者年龄(30.44±20.11)岁，屈光手术至发病时间(32.10±17.80)个月。4例(44.4%)马蹄形裂孔，1例(11.1%)萎缩性裂孔，4例(44.4%)巨大裂孔；9眼裂孔均位于赤道部前，除2眼(22.2%)为单个巨大裂孔，1眼(11.1%)单个马蹄孔，余6眼(66.7%)均有视网膜周边变性区存在；视网膜脱离范围(3.0±1.12)个象限，8例累及黄斑；增殖性玻璃体视网膜病变C级以上4眼。视网膜初始复位率为77.8%，最终视网膜复位率100%。末次随访最佳矫正视力优于术前(P<0.05)。随访期间，2例硅油填充眼发生并发性白内障，4眼发生术后早期高眼压。结论：有晶状体眼后房型人工晶状体植入术前存在的视网膜变性或术后玻璃体牵引的存在可能是孔源性视网膜脱离发生的危险因素。
Objective: To analyze the clinical presentation, surgical management, and outcomes of rhegmatogenous retinal detachment (RRD) in patients with high-myopia corrected by posterior chamber phakic (PCP) intraocular lens (IOL) implantation. Methods: Nine eyes of 9 patients in whom RRD developed after PCPIOL implantation from April 2012 to June 2021 in Zhongshan Ophthalmic Center were retrospectively studied. Mean follow-up after retinal detachment surgery was (4.96±4.78)months. Results: Mean patient age was (30.44±20.11) years old. RRD occurred (32.10±17.80) months after PCPIOL implantation. Four (44.4%) breaks were horseshoe tear, 1 (11.1%) was atrophic hole and 4 participants (44.4%) had a giant retinal tear. Nine cases had causative breaks located anterior to the equator while peripheral retina lattice degeneration was found in 6 eyes. RRD extended from 1 to 4 quadrants (3.0±1.12 quadrants) and 8 cases were macula-off retinal detachments. Four eyes’ proliferative vitreoretinopathy were more severe than level C. Initial reattachment rate was 77.80%. Final retinal reattachment was 100%. Final follow-up BCVA was significantly better than baseline (P<0.05). Furthermore, concurrent cataract occurred in 2 eyes in which silicone oil was used as tamponade. Ocular hypertension was detected in 4 eyes after surgery. Conclusion: The existed lattice degeneration and postoperative vitreous traction may be risk factors for RRD after PCPIOL implantation.
目的：评估屈光不正患者有晶体眼后房型人工晶体(implantable collamer lens，ICL)植入术后视疲劳症状及调节集合功能、眼表、像差的变化，并探讨其对视疲劳症状的影响。方法：前瞻性病例观察分析。连续收集在沧州市中心医院行ICL手术并完成3个月随访的患者，测定术前、术后1周、1个月、3个月时的视疲劳评分、调节幅度(amplitude of accommodation，AA)、正相对调节和负相对调节(positive/negative relative accommodation，PRA/NRA)、调节灵敏度(accommodative facility，AF)、调节性集合(accommodative convergence，AC)与调节(accommodation，A)比率(AC/A)，Schirmer实验、非侵入性泪膜破裂时间(noninvasive breakup time，NBUT)及高阶像差(higher order aberration，HOA)，进行统计学分析。结果：ICL术后第1周视疲劳症状较术前明显加重，随时间推移逐渐减轻，术后1个月仍高于术前，术后3个月时恢复。AA术后1周时较术前降低，术后1个月、3个月时明显高于术前；AF术后1周时较术前下降，术后1个月比术前水平稍好，3个月时明显高于术前；PRA、NRA无明显变化；AC/A术后1周时较术前下降，术后1个月回复到术前水平，术后3个月较术前提高。术后1周、1个月及3个月的NBUT值均较术前明显下降，术后1周时最低；Schiermer值术后1周时轻度下降，术后1个月、3个月时基本恢复。术后的总HOA均较术前有所增加，但各个时间点之间无明显变化。相关性分析显示ICL术后AF越差、NBUT越低，视疲劳症状越重。结论：ICL术后视疲劳症状一过性加重，AF和NBUT是影响视疲劳变化的重要因素。
Objective: To evaluate the changes of visual fatigue symptoms, accommodative functions, ocular surface conditions, and high-order aberrations (HOA) after implantation of implantable collamer lens (ICL), and to explore their effects on asthenopia. Methods: It was a prospective observational case series. Patients with ametropia who underwent ICL surgeries and completed 3-month follow-up in our hospital were enrolled.Asthenopia scores, amplitude of accommodation (AA), positive/negative relative accommodation (PRA/NRA),accommodative facility (AF), the ratio of accommodative convergence and accommodation (AC/A), Schirmer test, non-invasive breakup time (NBUT), and HOA were examined before surgeries and at 1 week, 1 month and 3 months after surgeries, then statistically analyzed. Results: Symptoms of asthenopia were significantly worse at 1 week after ICL surgeries than those before surgeries, but increased gradually as time went by, eventually recovered at 3 months postoperatively. Among regulatory indicators, AA decreased 1 week postoperatively, but was significantly higher at 1 and 3 months after surgeries; AF was lower 1 week after surgery than baseline, slightly better at 1 month postoperatively, and significantly higher at 3 months postoperatively; PRA and NRA had no significant change; AC/A decreased 1 week after surgeries, returned to the baseline at 1 month postoperatively, and increased 3 months postoperatively. Tears and meibomian gland function index: NBUT values at 1 week, 1 month and 3 months after surgeries were significantly decreased compared with those before surgeries, and NBUT at 1 week postoperatively was the lowest; Schiermer values had a slight decrease at 1 week after surgeries, and basically recovered at 1 and 3 months after surgeries. HOA after surgeries were increased compared with those before surgeries, but there was no significant change between each time point. Correlation analysis showed that the lower AF and NBUT after ICL surgeries, the more severe the asthenopia symptoms. Conclusion: The symptoms of asthenopia aggravated transiently after ICL implantation surgeries, but improved gradually with time. AF and NBUT were important factors affecting the changes of asthenopia.
