To compare visual outcomes in normal and complicated laser in situ keratomileusis (LASIK) flaps constructed with a femtosecond laser.
Wilford Hall Ambulatory Surgical Center, San Antonio, Texas.
Retrospective chart review.
The main outcome measures were uncorrected distance visual acuity (UDVA) and best-corrected distance visual acuity (CDVA) at 1 month post-surgery, which were compared in patients with and without complications during flap creation.
This retrospective chart review identified 586 eyes of 293 consecutive patients who had bilateral simultaneous femtosecond LASIK for myopia. A normal flap was attained in 539 (91.8%) of patients. At 1 month postoperatively, the mean UDVA was 20/19.1, and the CDVA was 20/16.8. 3 (0.51%) of patients experienced an incomplete side cut or intraoperative flap tear (the mean 1-month uncorrected distance visual acuity [UDVA] was 20/17.5 and the corrected distance visual acuity [CDVA] was 20/16.9 in both groups). Microstriae were seen in 28 (4.8%) of patients (mean 1-month UDVA, 20/21.7; CDVA, 20/17.4). Diffuse lamellar keratitis appeared in 4 (0.68%) of patients (mean 1-month UDVA, 20/21.7; CDVA, 20/15.6). Epithelial ingrowth developed in 9 (1.5%) of patients (mean 1-month UDVA, 20/18.7; CDVA, 20/16.9). There was no statistically significant difference in UDVA or CDVA at 1 month postoperatively between complicated and uncomplicated flaps (P > .05), and complicated flaps did not lose a statistically significant amount of CDVA or low-contrast acuity (CDVA 5%) compared to preoperative values.
Intraoperative and postoperative complications of LASIK flaps created with the femtosecond laser were rare, and their visual outcomes were equivalent to those of normal flaps.

比较使用飞秒激光制作的正常及复杂准分子原位角膜磨镶术（LASIK）瓣的视觉效果。
得克萨斯州圣安东尼奥市威尔福德·霍尔门诊手术中心。
回顾性病历审查。
主要观察指标为术后1个月时的未矫正远视力（UDVA）和最佳矫正远视力（CDVA），对制作角膜瓣过程中有无并发症的患者进行比较。
这项回顾性病历审查纳入了293例连续接受双眼同时飞秒LASIK治疗近视的患者的586只眼。539例（91.8%）患者获得了正常角膜瓣。术后1个月时，平均UDVA为20/19.1，CDVA为20/16.8。3例（0.51%）患者出现侧切不完全或术中角膜瓣撕裂（两组患者的平均术后1个月未矫正远视力[UDVA]均为20/17.5，矫正远视力[CDVA]均为20/16.9）。28例（4.8%）患者出现微条纹（平均术后1个月UDVA为20/21.7；CDVA为20/17.4）。4例（0.68%）患者出现弥漫性板层角膜炎（平均术后1个月UDVA为20/21.7；CDVA为20/15.6）。9例（1.5%）患者发生上皮内生（平均术后1个月UDVA为20/18.7；CDVA为20/16.9）。复杂瓣与未复杂瓣术后1个月时的UDVA或CDVA无统计学显著差异（P>.05），且与术前值相比，复杂瓣的CDVA或低对比度视力（CDVA 5%）无统计学显著下降。
飞秒激光制作LASIK瓣的术中及术后并发症罕见，其视觉效果与正常瓣相当。
