While laser in situ keratomileusis (LASIK) offers advantages over photorefractive keratectomy (PRK), creation of the corneal flap has been associated with postoperative flap striae. These result from misalignment of the corneal flap after flap replacement, movement of the corneal flap during the first postoperative day, or the "tenting effect" of the corneal flap over the ablated stromal bed. Flap striae become more difficult to remove as the postoperative course progresses; therefore, identifying the striae on the first postoperative day is imperative. We describe techniques of flap hydration, refloating, stretching, and smoothing that we use to remove visually significant flap striae.
虽然准分子激光原位角膜磨镶术（LASIK）比准分子激光角膜切削术（PRK）具有优势，但角膜瓣的制作与术后瓣下条纹有关。这些条纹是由于角膜瓣复位后角膜瓣未对齐、术后第一天角膜瓣移动或角膜瓣在消融的基质床上的“帐篷效应”所致。随着术后病程的进展，瓣下条纹越来越难以消除；因此，在术后第一天识别出这些条纹至关重要。我们描述了用于消除具有明显视觉影响的瓣下条纹的瓣水化、重新漂浮、拉伸和平滑技术。
