Two microkeratome heads (90 and 130) were used to created a flap with thickness of 120μm and 150μm,respectively. Thin flap group(120μm) included 75 eyes while thick flap group included 75 eyes. Follow-up period was 12 mo. Efficacy,l safety, and stability were evaluated and compared between the two groups.RESULTS: In 150 eyes,the mean preoperative spherical equivalent refraction was -8.65±2.6D,mean sphere was -4.4±3.5D, and mean cylinder was -1.0±1.3D. THe amount of ablation was significantly larger in the thin flap (88.5±32.21μm) group than in the thick flap group (64±28.13μm).Percentage of safety was higher in the thin flap group(94.8%) than in the thick flap group(91.7%). There were no intraoperative complications, especially flap-related problems. Subjective symptoms of dry eye occurred in 20.7% and 33.3% of eyes in the thin and thick flap groups, respectively. CONCLUSION: Thin-flap LASIK is effective and safe in correcting myopic defects. It achivevs better visual results, rapid visual recovery, and stable postoperative refraction than LASIK with thick flaps.展开更多

Case 1: A 53-year-old man with a skin ulcer over the anterior surface of the left tibia secondary to plate fixation for an open fracture. The perforator marked with preoperative Doppler was located 8 cm proximal to the superior border of the patella. Without thinning, the flap was 10 × 4 cm in size and 5 mm thick. Case 2: A 46-year-old man with necrosis of the right index finger after replantation. The flap was 5 × 3 cm in size and 3 mm in thickness. This “distal” anterolateral thigh flap can be raised as a quite thin flap with a long pedicle and, therefore, is considered useful in the reconstruction of various soft tissue defects.展开更多
