Implantation of intraocular lens in the capsular bag has become the standard of care in aphakic state. However, in the absence of capsular support, several techniques and intraocular lenses are available. Our study aims to report the safety, efficacy, and clinical outcomes of transconjunctival intrascleral intraocular lens fixation with Yamane's double-needle technique and flanged haptics.
Prospective, observational study with some retrospective data collection. The study enrolled 13 patients (16 eyes) who underwent transconjunctival intrascleral fixation of an intraocular lens with Yamane's technique between June 2017 and April 2019 at Dhahran Eye Specialist Hospital and King Fahd University Hospital. All patients underwent preoperative and postoperative comprehensive evaluation, including uncorrected and best-corrected vision, intraocular pressure, slit-lamp examination, dilated fundus examination, and ultrasound biomicroscopy. We excluded patients with visually significant coexistent pathology such as retinal diseases, glaucoma, follow-up less than three months, and combined surgery such as keratoplasty.
The mean preoperative uncorrected visual acuity was 1.50 logMAR, and it improved to 0.60 logMAR. The mean preoperative best-corrected visual acuity was 0.70 logMAR, and it improved to 0.40 logMAR. The median safety index was 2.0, and the median efficacy index was 1.58. The postoperative complications included iris capture by the intraocular lens in one eye (7.7%), haptic extrusion in one eye (7.7%), and transient cornea edema in one eye (7.7%). There were no detected reports during the follow-up period of postoperative retinal detachment, choroidal detachment, elevation of the intraocular pressure (> 25 mmHg), hypotony, hyphema, vitreous hemorrhage, or endophthalmitis.
The transconjunctival intrascleral fixation of an intraocular lens is safe and effective with a short learning curve and was not associated with significant intraoperative or postoperative complications.
在无晶状体眼状态下，将人工晶状体植入囊袋内已成为标准的治疗方法。然而，在缺乏囊袋支持的情况下，有几种技术和人工晶状体可供选择。我们的研究旨在报告使用 Yamane 双针技术和翼型襻的经结膜巩膜内眼内晶状体固定的安全性、有效性和临床结果。
这是一项前瞻性、观察性研究，部分数据为回顾性收集。该研究纳入了 2017 年 6 月至 2019 年 4 月在达兰眼科专科医院和法赫德国王大学医院接受 Yamane 技术经结膜巩膜内眼内晶状体固定的 13 名患者（16 只眼）。所有患者均接受了术前和术后的全面评估，包括未矫正视力和最佳矫正视力、眼压、裂隙灯检查、散瞳眼底检查和超声生物显微镜检查。我们排除了存在视网膜疾病、青光眼等明显并存病变、随访时间少于 3 个月以及合并角膜移植等联合手术的患者。
平均术前未矫正视力为 1.50 logMAR，术后提高至 0.60 logMAR。平均术前最佳矫正视力为 0.70 logMAR，术后提高至 0.40 logMAR。中位数安全指数为 2.0，中位数有效指数为 1.58。术后并发症包括 1 只眼（7.7%）的人工晶状体虹膜捕获、1 只眼（7.7%）的襻突出和 1 只眼（7.7%）的短暂性角膜水肿。在术后视网膜脱离、脉络膜脱离、眼压升高（>25mmHg）、低眼压、前房积血、玻璃体积血或眼内炎等的随访期间，均未发现相关报道。
经结膜巩膜内眼内晶状体固定是一种安全有效的方法，学习曲线短，且与明显的术中或术后并发症无关。
