To assess the visual and refractive outcome of immediate intraoperative vitrectomy and intrascleral intraocular lens implantation using a "standardized" sutureless Yamane technique during cataract luxation in the vitreous chamber as a complication of phacoemulsification.
A prospective, interventional, consecutive case series.
Twelve patients underwent vitrectomy and intrascleral intraocular lens fixation using a standardized Yamane technique as the primary procedure during complicated phacoemulsification. Patients were evaluated preoperatively and 6 months postoperatively for best-corrected distance visual acuity, correspondence to the preoperative refractive target in the spherical equivalent, endothelial cell count, and complications.
Mean preoperative best-corrected visual acuity was 1.16 ± 0.3 logarithm of the minimum angle of resolution (logMAR), the endothelial cell count was 1910.5 ± 297.64, and target refraction at baseline was -0.197 ± 0.087. Postoperatively, best-corrected visual acuity was significantly improved; the mean value was 0.05 logMAR ± 0.06. Mean baseline target refraction in the spherical equivalent was -0.20 ± -0.09 (range: -0.08 to -0.37), and mean final refraction was -0.44 ± -0.14 (range: -0.25 to -0.75) with no significant difference (=0.87). No complication was registered intra- and postoperatively.
Standardization of the Yamane technique seemed a valuable option for patients who had complicated phacoemulsification to achieve a predictable refractive outcome. . The predictable refractive outcome could be achieved with the immediate standardized Yamane technique in patients with intraoperative cataract luxation in the vitreous chamber during phacoemulsification.
评估在超声乳化白内障吸除术中晶状体脱位至玻璃体腔这一并发症发生时，采用“标准化”无缝线山根技术即刻进行术中玻璃体切除术及巩膜内人工晶状体植入术的视觉和屈光效果。
一项前瞻性、干预性、连续病例系列研究。
12例患者在复杂超声乳化白内障吸除术中，采用标准化山根技术进行玻璃体切除术及巩膜内人工晶状体固定术作为主要手术。术前及术后6个月对患者进行评估，内容包括最佳矫正远视力、等效球镜度与术前屈光目标的符合情况、内皮细胞计数及并发症。
术前平均最佳矫正视力为1.16±0.3最小分辨角对数（logMAR），内皮细胞计数为1910.5±297.64，基线目标屈光度为-0.197±0.087。术后，最佳矫正视力显著提高；平均值为0.05 logMAR±0.06。等效球镜度的平均基线目标屈光度为-0.20±-0.09（范围：-0.08至-0.37），平均最终屈光度为-0.44±-0.14（范围：-0.25至-0.75），差异无统计学意义（P=0.87）。术中和术后均未出现并发症。
对于复杂超声乳化白内障吸除术患者，山根技术的标准化似乎是实现可预测屈光效果的一个有价值的选择。在超声乳化白内障吸除术中发生术中晶状体脱位至玻璃体腔的患者中，采用即刻标准化山根技术可实现可预测的屈光效果。
