To report results of a modified Yamane technique for scleral fixation of the intraocular lens (IOL).
Data from all patients treated with scleral fixation using the Avansee AN6A at our hospital by a single surgeon were obtained and retrospectively analyzed from our database. In our technique, the trailing haptic was externally inserted into the lumen of the 30G needle. The preoperative measurements included three variables: best-corrected visual acuity (BCVA,Snellen), intraocular pressure (mmHg), and corneal endothelial cell count (cells/mm2). Postoperative measurements included: refractive error (D), aqueous depth (mm), tilt (°), decentration (mm), and the three preoperative variables.
This study included 20 eyes (mean age, 65.3±13.5 years). Preoperative conditions included lens subluxation (4 eyes), IOL dislocation (13 eyes), and aphakia (3 eyes). The BCVA improved from 20/32 preoperatively to20/20 postoperatively. The mean preoperative corneal endothelial cell density was 2,282 cells/mm2 and changed to 2,091 cells/mm2 at the last visit. Postoperative refractive error was slightly myopic (-0.13±1.4 D). Regarding the position of fixated IOLs, postoperative tilt was 5.57 ± 3.35°. and postoperative decentration was 0.50 ± 0.26 mm.
The simplified Yamane technique showed good overall clinical outcomes and stability of refractive predictability when performed by a single surgeon, making it easier to master. Further studies are required to expand on this simplified procedure.
报告改良矢根技术用于人工晶状体（IOL）巩膜固定的结果。
获取我院由单一外科医生使用Avansee AN6A进行巩膜固定治疗的所有患者的数据，并从我们的数据库中进行回顾性分析。在我们的技术中，将后袢从外部插入30G针的管腔。术前测量包括三个变量：最佳矫正视力（BCVA，斯内伦视力表）、眼压（mmHg）和角膜内皮细胞计数（细胞/mm²）。术后测量包括：屈光不正（D）、前房深度（mm）、倾斜度（°）、偏心（mm）以及三个术前变量。
本研究包括20只眼（平均年龄，65.3±13.5岁）。术前情况包括晶状体半脱位（4只眼）、IOL脱位（13只眼）和无晶状体眼（3只眼）。BCVA从术前的20/32提高到术后的20/20。术前角膜内皮细胞平均密度为2282个细胞/mm²，最后一次随访时变为2091个细胞/mm²。术后屈光不正为轻度近视（-0.13±1.4 D）。关于固定IOL的位置，术后倾斜度为5.57±3.35°，术后偏心度为0.50±0.26 mm。
简化的矢根技术在由单一外科医生操作时显示出良好的总体临床结果和屈光预测稳定性，使其更易于掌握。需要进一步研究以扩展这一简化程序。
