We developed a new method to retrieve a dropped nucleus of the lens via a small incision using bipolar pencils, the kebab technique, to solve the lack of small-gauge fragmatomes, and the expense and toxicity of perfluorocarbon liquids (PFCL). A total of 8 eyes in 6 patients underwent this technique and were reviewed. After vitrectomy, the dropped nucleus of the lens was lifted from the retina by adhesion with a bipolar pencil, and phacoemulsification was performed while rotating the lens. The outcome measures were best-corrected visual acuity (BCVA), intraocular pressure (IOP), and corneal endothelial cell density before and after surgery. Surgical indications included zonular weakness, trauma, acute angle closure attack, and phacolytic glaucoma. At 1 month, BCVA improved from a mean (standard deviation, SD) 1.67 logMAR (0.90) to 1.14 logMAR (1.01). The mean preoperative IOP was 24.5 (16.8) mmHg and postoperative IOP was 11.0 (2.8) mmHg. The mean preoperative corneal endothelial cell count was 2600 (322) cells/mm (one eye was unmeasurable) and postoperative corneal endothelial cell count was 2387 (431) cells/mm. There were no postoperative complications. The retrieval of a dropped nucleus of the lens using a bipolar pencil enables small incisions without using PFCL.
我们开发了一种新方法，即使用双极电凝笔通过小切口取出晶状体脱位核，也就是烤串技术，以解决小口径碎核刀的短缺问题以及全氟碳液体（PFCL）的费用和毒性问题。6例患者共8只眼接受了该技术并进行了回顾性研究。玻璃体切除术后，用双极电凝笔通过粘连将脱位的晶状体核从视网膜上提起，同时旋转晶状体进行超声乳化。观察指标为手术前后的最佳矫正视力（BCVA）、眼压（IOP）和角膜内皮细胞密度。手术适应证包括晶状体悬韧带薄弱、外伤、急性闭角型青光眼发作和晶状体溶解性青光眼。术后1个月，BCVA从平均（标准差，SD）1.67 logMAR（0.90）提高到1.14 logMAR（1.01）。术前平均眼压为24.5（16.8）mmHg，术后眼压为11.0（2.8）mmHg。术前平均角膜内皮细胞计数为2600（322）个/mm²（一只眼无法测量），术后角膜内皮细胞计数为2387（431）个/mm²。术后无并发症。使用双极电凝笔取出脱位的晶状体核可实现小切口且无需使用PFCL。
