To report complications of femtosecond laser-assisted re-treatment by the creation of side cuts within the old flaps for residual refractive error after primary LASIK in two patients.
Case report.
Three eyes of two patients had complications with a circumferential sliver of stromal tissue displaced during surgery due to overlap of old and new side cuts. The displaced tissue was repositioned and corneal anatomy was restored. Two of three eyes demonstrated improvement in the uncorrected visual acuity, whereas one eye lost two lines of corrected visual acuity due to loss of tissue at side cut resulting from flap manipulation, which was done at 1 week.
These cases demonstrate a complication of femtosecond laser-enabled side-cut for LASIK enhancement and factors that may lead to this complication and precautions to avoid it.
报告 2 例患者在 LASIK 术后，通过在旧瓣内创建侧切口来矫正残余屈光不正，从而导致飞秒激光辅助重治疗的并发症。
病例报告。
两名患者的 3 只眼在手术过程中由于新旧侧切口重叠，导致环形的一小片基质组织移位。移位的组织被重新定位，角膜解剖结构得到恢复。3 只眼中有 2 只眼的未矫正视力得到改善，而有 1 只眼由于瓣操作导致侧切口处组织丢失，在 1 周时损失了两行矫正视力。
这些病例表明了飞秒激光辅助 LASIK 增强的侧切口所导致的一种并发症，以及可能导致这种并发症的因素和避免这种并发症的注意事项。
