To report a novel technique for refixation of dislocated CZ70BD intraocular lens (IOL).
Vitrectomy trocars are placed along the horizontal meridian 5 mm apart. A CV-8 Gore-Tex suture is introduced through a bare sclerotomy into the midvitreous cavity. Under chandelier illumination, a 27 G broad platform forceps is threaded through the eyelet of the dislocated CZ70BD IOL. Using another pair of intraocular forceps, the free intraocular end of the Gore-Tex suture is fed to the broad platform forceps and externalized, thus repositioning the IOL. Particular attention is drawn to pass the suture in an over and under configuration to avoid IOL tilt. An identical procedure is repeated for the other eyelet if the IOL is completely dislocated. The 23 gauge or 25 gauge instruments should not be used for this technique because they do not fit loosely through the eyelets of the IOL.
Three eyes were successfully operated on using this technique with at least 6 months of follow-up. There was significant improvement in best-corrected visual acuity after the operation. Postoperative IOL centration and alignment were satisfactory.
The described surgical technique is effective for transscleral Gore-Tex-assisted refixation of dislocated CZ70BD IOL.
报告一种新型技术，用于修复脱位的 CZ70BD 人工晶状体（IOL）。
沿着水平子午线放置 5 毫米间隔的玻璃体切割套管。将 CV-8 Gore-Tex 缝线通过无套索的巩膜切开术引入玻璃体内腔。在吊灯照明下，将 27G 宽平台镊子穿过脱位的 CZ70BD IOL 的眼环。使用另一对眼内镊子，将 Gore-Tex 缝线的游离眼内端送入宽平台镊子并引出，从而重新定位 IOL。特别注意缝线采用上下交错的方式穿过，以避免 IOL 倾斜。如果 IOL 完全脱位，则对另一个眼环重复相同的步骤。由于 23 号或 25 号器械不能宽松地穿过 IOL 的眼环，因此不适合使用该技术。
使用该技术对 3 只眼睛进行了成功的手术，随访时间至少为 6 个月。术后最佳矫正视力有显著改善。术后 IOL 中心定位和对齐情况满意。
所描述的手术技术对于经巩膜 Gore-Tex 辅助修复脱位的 CZ70BD IOL 是有效的。
