Abstract

BACKGROUND

To evaluate the clinical efficacy of a novel surgical technique using a 25-gauge active aspiration of flute needle for treating the dislocation of posterior intraocular lens (IOL).

METHODS

This retrospective study included 12 eyes in 12 patients with posterior dislocated IOL. All patients underwent comprehensive ophthalmic evaluations before surgery. Surgery was performed with three-port pars plana vitrectomy, the dislocated IOL was aspirated to the anterior vitreous by a 25-gauge flute needle, and then managed by different surgical corrections. Comprehensive ophthalmologic assessment was performed preoperatively and postoperatively, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy and fundus examination. Postoperative assessments were conducted at 1 week, 1 month, and 3 months.

RESULTS

Twelve eyes were treated. All surgeries were successfully completed using a 25-gauge silicone tip with active aspiration. IOL repositioning without sutures in 1 case (8.3%), IOL repositioning with scleral sutures in 4 cases (33.3%), IOL exchanged with Yamane technique in 4 cases (33.3%) and IOL exchange with scleral sutures in 3 cases (25.0%). The mean follow-up time was 13.08 ± 5.49months (range 5–20 months). The mean BCVA preoperatively was log MAR 0.48 ± 0.33 (range 0.0-1.3), recovered to log MAR 0.34 ± 0.22 (range 0.0-0.7) at three-month postoperatively. The BCVA was improved at the three-month follow-up compared with preoperatively (t = 2.40, = 0.035 < 0.05). IOP remained stable except for one patient who developed transient high IOP, but well controlled by medications.

CONCLUSIONS

An active aspiration of flute needle with silicon tip provides a simplified, efficient and safe method for IOL dislocation, minimizing the needs of perfluorocarbon liquids as well as intraocular-forceps.

摘要

背景

评估一种使用25G带主动抽吸功能的笛形针治疗后房型人工晶状体（IOL）脱位的新型手术技术的临床疗效。

方法

这项回顾性研究纳入了12例后房型人工晶状体脱位患者的12只眼。所有患者在手术前均接受了全面的眼科评估。采用三通道玻璃体切割术进行手术，用25G笛形针将脱位的人工晶状体抽吸至玻璃体前部，然后采用不同的手术矫正方法进行处理。术前和术后进行全面的眼科评估，包括最佳矫正视力（BCVA）、眼压（IOP）、裂隙灯显微镜检查和眼底检查。术后在1周、1个月和3个月进行评估。

结果

共治疗12只眼。所有手术均使用带主动抽吸功能的25G硅胶头成功完成。1例（8.3%）人工晶状体无缝线复位，4例（33.3%）人工晶状体经巩膜缝线复位，4例（33.3%）采用山根技术更换人工晶状体，3例（25.0%）经巩膜缝线更换人工晶状体。平均随访时间为13.08±5.49个月（范围5 - 20个月）。术前平均BCVA为log MAR 0.48±0.33（范围0.0 - 1.3），术后3个月恢复至log MAR 0.34±0.22（范围0.0 - 0.7）。与术前相比，3个月随访时BCVA有所改善（t = 2.40，P = 0.035 < 0.05）。除1例患者出现短暂性高眼压但经药物良好控制外，眼压保持稳定。
