To describe a novel suture approach for transscleral fixation of C-loop intraocular lenses (IOL) and to compare the surgical outcomes with the four-haptics posterior chamber (PC)-IOL technique.
We retrospectively analyzed 16 eyes of 16 patients who underwent transscleral fixation of C-loop PC-IOLs using a flapless one-knot suture technique, which were followed up for longer than 17mo. In this technique, the capsulorless IOL was suspended using a single suture for transscleral fixation of four feet. Then we compared its surgical outcomes and complications with the four-haptics PC-IOLs using the Student's test and Chi-square test.
Sixteen patients of 16 eyes with a mean age of 58.3±10.1y (42-76y) who received transscleral C-loop IOL implantation due to trauma, vitrectomy, or cataract surgery with inadequate capsule support showed improved visual acuity. The difference was not significant between two IOLs except the surgery time (>0.05). The mean operation times of C-loop IOL surgery was 24.1±1.83min and 31.3±4.47min of the four-haptics PC-IOL method (<0.0001). In the C-loop IOLs group, there was statistical difference between the preoperative and the postoperative UCVA (logMAR, 1.20±0.50 0.57±0.32, =0.0003). There was no statistical difference between the preoperative and the postoperative BCVA (logMAR, 0.66±0.46 0.40±0.23, =0.056). However, there was no statistically significant difference in postoperative UCVA and BCVA between the two IOLs (>0.05). We did not detect any optic capture, IOL decentration or dislocation, suture exposed, or cystoid macular edema in patients underwent C-loop IOLs surgery.
The novel flapless one-knot suture technique for transscleral fixation of C-loop IOL is a simple, reliable, and stable technique.
描述一种用于C襻人工晶状体（IOL）经巩膜固定的新型缝合方法，并将手术结果与四襻后房型（PC）IOL技术进行比较。
我们回顾性分析了16例患者的16只眼，这些患者采用无瓣单结缝合技术进行了C襻PC-IOL的经巩膜固定，随访时间超过17个月。在该技术中，无囊IOL使用单根缝线悬吊，用于四襻的经巩膜固定。然后我们使用Student检验和卡方检验比较其手术结果和并发症与四襻PC-IOLs的情况。
16例患者的16只眼，平均年龄58.3±10.1岁（42-76岁），因外伤、玻璃体切除术或囊膜支持不足的白内障手术而接受经巩膜C襻IOL植入，视力均有改善。除手术时间外，两种IOL之间差异无统计学意义（>0.05）。C襻IOL手术的平均手术时间为24.1±1.83分钟，四襻PC-IOL方法为31.3±4.47分钟（<0.0001）。在C襻IOLs组中，术前与术后最佳矫正视力（UCVA，logMAR）有统计学差异（1.20±0.50对0.57±0.32，P=0.0003）。术前与术后最佳矫正视力（BCVA，logMAR）无统计学差异（0.66±0.46对0.40±0.23，P=0.056）。然而，两种IOL术后UCVA和BCVA无统计学显著差异（>0.05）。接受C襻IOLs手术的患者未发现任何光学捕获、IOL偏心或脱位、缝线外露或黄斑囊样水肿。
用于C襻IOL经巩膜固定的新型无瓣单结缝合技术是一种简单、可靠且稳定的技术。
