AIM:To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses(IOLs).METHODS:This study retrospectively enrolled a consecutive series of patients who underwent a surgery of sutured existing subluxated or dislocated IOLs from October 2018 to June 2020.All patients underwent comprehensive preoperative and postoperative ophthalmologic examination,and data were collected including age,sex,surgical indications,best-corrected visual acuity,refractive error,intraocular pressure.Presence of intraoperative and postoperative surgical complications was documented.RESULTS:A total of 20 consecutive cases were enrolled for analysis with mean final follow-up period 9.8±5.3mo.Visual acuity improved from a mean of 0.35(0.46±0.32 logMAR)preoperatively to 0.61(0.21±0.18 logMAR)at the 3-month follow-up(P=0.002).The mean amount of preoperative keratometric astigmatism and total postoperative refractive astigmatism was-1.24±0.80 diopters(D)and-1.42±0.97 D,respectively.There was no statistically significant difference between preoperative and postoperative astigmatism(P=0.156).The mean IOL-induced astigmatism was-0.23±0.53 D.The mean spherical equivalent at the 3-month follow-up was-0.1±0.94 D.No major complications were noted during the follow-up period.CONCLUSION:Surgical techniques using sutured scleral fixation of existing subluxated or dislocated acrylic one-piece IOLs result in favorable visual and refractive outcomes without major complications.

Efficacy of Removing Dislocated Lens using Intravitreal Phacoemulsification

Purpose:To evaluate the efficacy of intravitreal phacoemulsification in the removal of dislocated crystalline lenses.Methods:Twenty-two cases (22 eyes) with posterior dislocated lens induced by ocular trauma or capsule rupture during phacoemulsification between January 2008 and December 2010 were retrospectively analyzed in this study.Total vitrectomy was first performed through standard closed three-port incisions at the pars plana,and dislocated lenses were removed using the phacoemulsification tip without the silicone sleeve.Extraction of intraocular foreign body,endolaser retinal photocoagulation and intraocular lens implantation were performed simultaneously.Visual acuity,intraocular pressure (IOP) and postoperative complications were assessed over 1 to 3 months of follow up.Results:All dislocated lenses were extracted without severe complication.The final corrected visual acuity was ≥ 6 /15 in 7 cases,6 /100-6 /18 in 5 cases and ≤ 6 /120 in 10 cases,a significant improvement over preoperative values (P <0.05).The IOP in 10 cases (10 eyes) with secondary glaucoma was < 21 mmHg post-operatively.Intraocular foreign bodies in 3 eyes were removed.Nine patients (9 eyes) underwent intraocular lens implantation.No instances of retinal detachment,retinal hemorrhage or scleral wound burn were observed after surgery.Conclusion:Intravitreal phacoemulsification combined with vitrectomy yielded good efficacy and safety in the treatment of posteriorly dislocated lens.It may be an alternative to phacofragmentation in the treatment of posteriorly dislocated lenses.

Posterior segment nucleotomy for dislocated sclerotic cataractous lens using chandelier endoilluminator and sharp tipped chopper

· AIM: To describe a new surgical technique for managing dislocated sclerotic cataractous lens.· METHODS: Six patients with advanced posteriorly dislocated cataracts were operated at a tertiary care centre and analyzed retrospectively. After standard 3 port23 G pars plana vitrectomy and perfluorocarbon liquid(PFCL) injection, the dislocated white cataract was held with occlusion using phaco fragmatome and then chopped into smaller pieces with a sharp tipped chopper using 25 G chandelier endoilluminator. Each piece was emulsified individually. Following aspiration of PFCL,Fluid Air Exchange was done in all the cases and surgery completed uneventfully.·RESULTS: Best corrected visual acuity(BCVA) in all the patients was better than 6/12 after one month of follow up. No serious complications were noted till minimum 6mo of follow up.·CONCLUSION: Four port posterior segment nucleotomy with a chandelier endoilluminator, fragmatome and a chopper appears to be a safe, easy and effective procedure for managing dislocated sclerotic cataractous nuclei. Ultrasonic energy used and adverse thermal effects of the fragmatome on the sclera may be lesser.

23-Gauge Pars Plana Vitrectomy Alone by a Bimanual Technique for the Removal of Dense Posteriorly Dislocated Crystalline Lens

Background: We sought to verify the efficacy and safety of transconjunctival 23-gauge pars plana vitrectomy (PPV) alone by our bimanual technique for the removal of dense posteriorly dislocated crystalline lens. Methods: A retrospective, noncomparative, interventional study of 31 consecutive cases of patients who underwent 23-gauge PPV alone for the removal of dense posteriorly dislocated crystalline lens following complicated cataract surgeries using our bimanual technique was conducted. The main outcomes measured included best-corrected visual acuity (BCVA), preoperative intraocular pressure (IOP), postoperative IOP and postoperative complications. Results: In all 31 cases included in this study, those dense posteriorly dislocated crystalline lenses were successfully removed. The enrolled patients consisted of 17 males and 14 females with a mean age of (75.84 ± 6.17) years (range 59 - 90). The mean follow-up length was (7.61 ± 1.87) months with a range of 6 months to 1 year. The mean preoperative BCVA was 0.22 ± 0.11 logMAR system, and the postoperative BCVA was 0.33 ± 0.07 logMAR system after 6 months of follow-up. The mean operative time was 46.32 ± 4.80 minutes with a range of 38.00 to 57.00 minutes. All of the conjunctival incisions self-closed within the first week with no wound leakage or hemorrhage. The postoperative complications were relatively rare. Conclusions: The removal of dense posteriorly dislocated crystalline lens might be a challenge for micro-incision vitrectomy. Our bimanual technique was proved to be an effective and safe method for those particular dense lenses using 23-gauge alone.

Summary of Home Nursing for Lens Dislocation Among Patients with Marfan Syndrome

Marfan syndrome is a rare genetic disease,and the condition of most patients deteriorates with age.The lesions are mainly cardiovascular,skeletal,and ocular lesions.Its clinical manifestations are characterized by congenital heart disease,ectopic lens,slender body,slender limbs,spider fingers(toes),and general muscle dysplasia.In the early stage of this disease,when the symptoms are not yet clearly manifested,some patients came to the hospital for treatment due to decreased vision.According to the particularity of crystal dislocation patients with Marfan syndrome,this article provides home nursing education in terms of physiological and psychological aspects,and builds an effective home nursing model to promote the physical and mental recovery of patients.

Concurrent removal of intravitreal lens fragments after phacoemulsification with pars plana vitrectomy prevents development of retinal detachment

AIM: To evaluate the outcomes of "concurrent vitrectomy" to retrieve dislocated lens fragment during phacoemulsification.METHODS: In a retrospective, observational case series, data of patients who underwent "concurrent" pars plana vitrectomy(PPV) for dislocated lens fragments between the period 2000 and 2008 were reviewed. Data collected included patient demographics, pre-operative visual acuity, intra-operative occurrence of retinal breaks, duration of follow up, post-operative intraocular pressure, final best-corrected visual acuity(BCVA),presence of cystoid macular edema(CME) and occurrence of rhegmatogenous retinal detachment(RRD).· RESULTS: A total of 58 eyes of 58 patients were included in the study. At 12 mo the mean postoperative BCVA was log MAR 0.17(20/30) with a range of log MAR0 to 0.69(20/20 to 20/100), with 96.6%(56/58) of patients showing post- operative improvement in visual acuity(P =0.005). None of the patients developed postoperative retinal detachment, endophthalmitis or non-resolving uveitis at 12 mo.CONCLUSION: Our study results suggest concurrent PPV for retained lens fragments after cataract surgery is beneficial and may decrease the risk of glaucoma and prevent development of RRD.

人工晶状体前脱位的手术策略

后房型人工晶状体(IOL)前脱位是白内障手术后的并发症之一,主要由于IOL固定不良或囊袋支持力不足等原因引起。虽然这一并发症的发生率并不高,但脱位的IOL可能导致角膜内皮损伤、瞳孔变形、视觉障碍等严重问题,因此依然值得临床医师重点关注。在遇到相关情况时,应及时进行全面评估和及时处理。本述评通过回顾既往研究,分析了IOL前脱位的发生率、风险因素及临床表现,详细阐述了术前评估要点、手术时机选择及具体手术处理策略,提出了针对不同脱位情况的手术方案,包括无缝线或使用缝线的IOL复位、IOL-囊袋复合物复位,以及必要情况下的IOL置换等,并对瞳孔、玻璃体、视网膜等其他眼内组织的术中处理给出了建议。

先天性晶状体脱位患者术后人工晶状体脱位的原因及其危险因素分析

目的探究先天性晶状体脱位(CEL)患者经巩膜人工晶状体(IOL)缝襻固定术后发生IOL脱位的原因及其危险因素分析。方法对123例(220眼)接受经巩膜IOL缝襻固定术的CEL患者进行回顾性分析,所有患者均接受全面的眼科检查,包括视力(VA)、眼压(IOP)及IOL位置等。采用广义估计方程分析评估CEL患者术后IOL脱位的危险因素。结果在随访期间(随访时间:36~94个月;中位随访时间:48个月),共有16例(17眼)术后发生IOL脱位,发生时间为术后2~78个月,平均为术后(38.2±23.3)个月。缝线断裂、缝线松脱、IOL襻断裂和术后眼外伤是导致IOL脱位的主要原因。广义估计方程分析显示,男性(OR:7.897,95%CI:1.025~60.859,P=0.047)、三片式IOL(AR40e,OR:3.344,95%CI:1.092~10.237,P=0.034)、眼外伤(OR:18.874,95%CI:2.271~156.849,P=0.007)及术后眼轴增长(OR:2.215,95%CI:1.022~4.800,P=0.044)是CEL患者术后IOL脱位的危险因素。结论IOL脱位是CEL患者经巩膜IOL缝襻固定术后的一种相对罕见但重要的远期并发症,其中缝线断裂和松脱为主要原因。因此,在缝线的选择和手术固定技术方面仍需要进一步研究和优化,以降低术后IOL脱位的风险。同时术后应加强随访,特别是对于男性患者,以便及时发现和处理可能出现的并发症。

Misdiagnosis induced intraocular lens dislocation in anterior megalophthalmos

Anterior megalophthalmos （AM） is an uncommon developmental anomaly of the anterior segment of the eye with a constellation of findings that includes enlarged cornea, deep anterior chamber, posterior positioning of the iris and lens, iris stroma atrophy, hypoplasia of iris dilator, pupil displacement, large capsular bag, lens subluxation, prematurely diagnose. We present 3 AM cases that were misdiagnosed as congenital cataract with weak zonule and megalocornea. Intraocular lenses （IOLs） dislocated after standard cataract surgeries and subsequent surgery （replacing the dislocated IOLs with iris-claw intraocular lenses） achieved satisfactory outcome. Although rare, AM should be included in the differential diagnosis of enlarged cornea and we recommend implanting Artisan lens in AM patients.

改良囊袋张力环联合囊袋内人工晶状体植入治疗马方综合征晶状体不全脱位术后人工晶状体脱位的临床特征及手术治疗

目的观察接受改良囊袋张力环(MCTR)联合囊袋内人工晶状体(IOL)植入治疗的马方综合征(MFS)晶状体不全脱位患者术后IOL脱位的发生率,并总结接受IOL复位或取出术MFS患者的临床特征。方法通过随访观察2015年1月—2020年6月于我院同一手术医师行MCTR植入术且术后随访3年以上的MFS患者术后IOL脱位情况,计算其IOL脱位发生率。通过回顾分析我院同期就诊的MFS合并IOL脱位患者的临床资料,分析其临床特征和手术选择。结果本研究共纳入同一手术医师行MCTR植入术患者115例(192眼),大部分患者为儿童(80.21%,154/192),中位随访时间4年(四分位范围:3.50,4.67)。随访期间共出现MCTR-IOL复合体脱位3例(3眼),脱位发生率为1.56%(3/192),其中2例为不全脱位、1例为全脱位。3例患者均为成人,IOL脱位发生时间为术后2~3年,均无明显诱因,直接原因均为缝线断裂。同期在我院接受IOL复位或取出术的MFS患者共16例。IOL脱位最常见的直接原因是缝线断裂(62.50%,10/16)、其次是缝线或可植入式囊袋拉钩在巩膜层间出现滑动松脱(18.75%,3/16)。对于出现不全脱位的CTR或MCTR患者,通过缝线再次固定张力环或植入囊袋拉钩可实现IOL复位;MCTR脱位进入玻璃体腔的患者接受了MCTR取出和经巩膜后房型IOL缝线固定术;对于其他手术方式的IOL脱位患者,多数患者实现了脱位IOL复位术(54.55%,7/13),少数患者进行了IOL置换术(30.77%,4/13),2例IOL取出后未植入IOL。结论MCTR植入术是治疗MFS合并晶状体不全脱位的一种安全、有效的手术方式,IOL脱位是其罕见并发症。MFS患者术后定期随访十分必要,甚至需要终生随访,早期干预IOL脱位可以取得较好的疗效。
