Lenticule fragments retained postoperatively are a unique complication of small incision lenticule extraction. Large or central remnants with pursuant complications, including irregular astigmatism, induced corneal aberrations, and reduction in visual acuity, warrant surgical removal. Currently described modalities to delineate lenticule remnants include the use of anterior segment optical coherence tomography or CIRCLE software. However, the incurred cost and restricted availability of the described techniques limit their widespread use. The intraoperative administration of diluted triamcinolone acetonide into the intrastromal pocket to delineate lenticule edges, aiding subsequent removal is shown here.
术后遗留的透镜碎片是小切口微透镜提取的一种独特并发症。大的或中央的残留物伴有随之而来的并发症，包括不规则散光、诱导的角膜像差和视力下降，需要手术切除。目前用于描绘透镜残留物的方法包括使用眼前节光学相干断层扫描或 CIRCLE 软件。然而，所描述技术的高昂成本和有限的可用性限制了它们的广泛应用。这里显示了在基质袋内局部注射稀释的曲安奈德以描绘透镜边缘，有助于随后的切除。
