To assess the efficacy and safety of a simple, noninvasive, "flap-sliding" technique for managing flap striae following laser in situ keratomileusis (LASIK).
This prospective, interventional study included eyes with post-LASIK flap striae. All eyes underwent flap sliding 1-2 days after surgery. Following flap edge epithelialisation, a cellulose sponge was used to gently slide the flap perpendicular to the striae direction. This technique allows for flap striae treatment without flap lifting, avoiding any associated lifting complications. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and refractive error were monitored one day after the flap-sliding procedure.
Fifteen eyes (15 patients) with post-LASIK flap striae were managed using the flap-sliding technique. The procedure did not successfully relocate the flap striae in 1 eye, and flap elevation and floating (using a balanced salt solution) were required. Therefore, 14 eyes were included in post-flap-sliding analyses. The UDVA improved in all patients the first day after the flap-sliding procedure was performed, with 11 of 14 eyes (78.57%) reaching an UDVA of 20/25 or better. Complications following flap sliding occurred in 2 eyes (14.29%). One eye had intraoperative epithelial abrasion, and 1 eye had residual postoperative striae outside of the optical zone.
The flap-sliding technique is a simple, noninvasive, efficient, and safe technique for managing post-LASIK flap striae that develop after epithelial healing in the early post-LASIK period. This trial is registered with NCT04055337.
评估一种简单、无创的“瓣滑动”技术用于处理准分子原位角膜磨镶术（LASIK）后瓣裂的有效性和安全性。
这项前瞻性干预性研究纳入了LASIK术后出现瓣裂的眼睛。所有眼睛在术后1 - 2天进行瓣滑动。在瓣边缘上皮化后，使用纤维素海绵垂直于瓣裂方向轻轻滑动瓣。该技术允许在不掀起瓣的情况下治疗瓣裂，避免任何相关的掀起并发症。在瓣滑动术后一天监测未矫正远视力（UDVA）、矫正远视力（CDVA）和屈光不正。
15只眼睛（15例患者）的LASIK术后瓣裂采用瓣滑动技术处理。该操作在1只眼中未成功重新定位瓣裂，需要掀起瓣并用平衡盐溶液漂浮。因此，14只眼睛纳入瓣滑动术后分析。在进行瓣滑动术后第一天，所有患者的UDVA均有改善，14只眼中有11只（78.57%）达到UDVA 20/25或更好。瓣滑动术后并发症发生在2只眼中（14.29%）。1只眼术中出现上皮擦伤，1只眼在光学区外有术后残留瓣裂。
瓣滑动技术是一种简单、无创、有效且安全的技术，用于处理LASIK术后早期上皮愈合后出现的瓣裂。本试验已在ClinicalTrials.gov注册，注册号为NCT04055337。
