  • 文章类型: Journal Article
    白内障手术是全球范围内最常见的外科手术之一。白内障摘除成功后,通常将人工晶状体(IOL)植入物放置在囊袋中。然而,在没有足够的囊膜支撑的情况下,IOL可以放置在前房中,固定在虹膜或巩膜上。本研究的目的是报告使用巩膜瓣的经巩膜缝合人工晶状体(IOL)技术的临床结果和安全性。玻璃体切除术,和Gore-Tex缝合后房型人工晶状体。
    回顾性,使用Gore-Tex缝合并同时进行玻璃体切除术进行人工晶状体巩膜固定的介入病例系列。以最小分辨率视敏度(logMARBCVA)的对数进行眼部检查,眼压测定,并在术后1,3,6和12个月对所有患者进行裂隙灯生物显微镜检查。记录所有术后并发症。
    纳入25例患者的25只眼。平均logMARBCVA从术前的0.43±0.36(20\\40Snellen当量)提高到术后12个月的0.13±0.18(20\\25Snellen当量)(p<0.01)。适应症包括手术无晶状体眼(16)和脱位晶状体植入物(9)。没有IOL混浊的病例,脉络膜上腔出血,术后眼内炎,人工晶状体脱位,Gore-Tex暴露,或在随访期间观察到视网膜脱离。
    使用Gore-Tex缝线加巩膜瓣对人工晶状体进行外巩膜固定的耐受性良好,并且缝线剥脱率非常低。此外,我们的研究证实了手术后良好的屈光效果.
    UNASSIGNED: Cataract surgery is one of the most common surgical procedures performed worldwide. Intraocular lens (IOL) implants are placed routinely in the capsular bag after successful cataract extraction. However, in the absence of adequate capsular support, IOL may be placed in the anterior chamber, fixated to the iris or fixated to the sclera. The purpose of this study is to report the clinical outcomes and safety profile of a trans-scleral sutured intraocular lens (IOL) technique using scleral flaps, vitrectomy, and Gore-Tex suture to place posterior chamber IOL.
    UNASSIGNED: Retrospective, interventional case series of eyes undergoing scleral fixation of an IOL using Gore-Tex suture with concurrent vitrectomy. Ocular examination with the logarithm of the minimum angle of resolution visual acuity (logMAR BCVA), tonometry, and slit-lamp biomicroscopy was performed on all patients at 1, 3, 6, and 12 months after the operation. All post-operative complications were recorded.
    UNASSIGNED: Twenty-five eyes of 25 patients were included. Mean logMAR BCVA improved from 0.43 ± 0.36 (20\\40 Snellen equivalent) preoperatively to 0.13 ± 0.18 (20\\25 Snellen equivalent) postoperatively at 12 months (p<0.01). Indications included surgical aphakia (16) and dislocated lens implant (9). No cases of IOL opacification, suprachoroidal haemorrhage, post-operative endophthalmitis, IOL dislocation, Gore-Tex exposure, or retinal detachment were observed during the follow-up period.
    UNASSIGNED: Ab externo scleral fixation of IOLs with Gore-Tex suture plus scleral flap is well tolerated and associated with a very low rate of suture exposition. Moreover, our study confirms excellent refractive outcomes after surgery.

    背景:我们的研究目的是比较四点巩膜固定(AkreosAO60)和Yamane技术(AcrySofMA60AC)两种巩膜固定人工晶状体(IOL)方法的安全性和有效性。
    方法:这种前瞻性,2021年至2023年在华沙的军事医学研究所-国家研究所进行了随机研究.我们比较了两组无晶状体眼的病因,眼部病史,屈光状态,和并发症。
    结果:我们的研究包括47名患者的50只眼。25只眼进行四点固定(第1组),25只眼采用Yamane技术(第2组)。手术时间1组为24.1min±8.9,2组为25.1min±9.9(p>0.05)。第1组和第2组术后1年最佳矫正视力(BCVA)分别为0.10±0.15和0.09±0.17logMAR,分别为(p>0.05)。术后总屈光不正(RE)为-0.06±0.71屈光度(D),而Yamane技术为0.83±0.70D(p<0.05)。第1组和第2组的内皮细胞密度(ECD)损失分别为0.9%和3.5%(p>0.05)。在使用Yamane技术进行手术的患者组中,前房和玻璃体出血更为频繁(10例,20%,p=0.01)。在第2组中,1例(2%)发现IOL移位。
    结论:两种分析技术均具有良好的耐受性,并确保良好的屈光效果(在四点巩膜固定术中非常可预测),并且具有相似的安全性。人工晶状体的四点巩膜固定似乎是安全的,对年轻人有效和有益,活跃的患者,尤其是在外伤或复发性半脱位后。

    BACKGROUND: The purpose of our study was to compare the safety and efficacy of two scleral fixation intraocular lens (IOL) methods of four-point scleral fixation (Akreos AO60) and the Yamane technique (AcrySof MA60AC).
    METHODS: This prospective, randomized study was conducted at the Military Institute of Medicine-National Research Institute in Warsaw between 2021 and 2023. We compared both groups for cause of aphakia, ocular history, refractive status, and complication.
    RESULTS: Our study included 50 eyes from 47 patients. Four-point fixation was performed in 25 eyes (group 1), and the Yamane technique was used in 25 eyes (group 2). Surgical time was 24.1 min ± 8.9 in group 1 and 25.1 min ± 9.9 in group 2 (p > 0.05). The postoperative BCVA (best-corrected visual acuity) for group 1 and group 2 at 1 year\'s observation was 0.10 ± 0.15 and 0.09 ± 0.17 logMAR, respectively (p > 0.05). Postoperative total refractive error (RE) was - 0.06 ± 0.71 diopters (D) for four-point scleral fixation and 0.83 ± 0.70 D for Yamane technique (p < 0.05). Endothelial cell density (ECD) loss was 0.9% in group 1 and 3.5% in group 2 (p > 0.05). Bleeding into the anterior chamber and vitreous body was more frequent in the group of patients operated on with the use of the Yamane technique (10 cases, 20%, p = 0.01). IOL displacement was found in one case (2%) in group 2.
    CONCLUSIONS: Both analyzed techniques are well tolerated and ensure good refractive results (extremely predictable in four-point scleral fixation) and have a similar safety profile. Four-point scleral fixation of IOL would appear to be safe, effective and beneficial for young, active patients, especially after trauma or recurrent subluxation.
    BACKGROUND: ClinicalTrials.gov identifier NCT06389643.

    OBJECTIVE: To compare visual, anatomical and economical outcomes of patients with secondary anterior chamber intraocular lens (AC-IOL) implantation and secondary scleral fixated intraocular lens (SF-IOL) implantation.
    METHODS: In this retrospective observational study, 38 aphakic patients after complicated phacoemulsification divided in two groups, AC-IOL group (17 patients receiving AC-IOL implantation) and SF-IOL group (21 patients receiving SF-IOL implantation). Corrected distance visual acuity (CDVA), patient reported visual outcome (VF-14) and endothelial cell density (ECD) were measured at baseline and two-year follow-up. Complication rate was registered. The global cost of each procedure and the incremental cost-effectiveness ratio (ICER) were calculated.
    RESULTS: No statistically significant difference was found in CDVA (logMAR 0.24 ± 0.17 vs. 0.32 ± 0.26, p = 0.27), VF-14 (68 ± 18 vs. 61 ± 20, p = 0.24), ECD (1456.48 ± 525.15 vs. 1341.71 ± 374.33, p = 0.48) and overall complication rate (p = 0.79) postoperatively between the SF-IOL group and the AC-IOL group. The ECD loss rate was significantly higher in the AC-IOL group (15.5% vs. 3.5%, p = 0.004). The average global cost of the two procedures was higher in the SF-IOL group (p < 0.005) and ICER showed an additional payment of 693 € for each patient in SF-IOL group against a saving of 186 endothelial cells 2 years postoperatively.
    CONCLUSIONS: AC IOL and SF-IOL implantation showed similar outcomes in terms of visual function and safety profile. Higher ECD loss was found in AC-IOL group. The global cost of implantation was significantly lower for AC-IOL, but the ICER seems to justify the SF-IOL implantation in patients with low ECD.
