目的：评价准分子激光角膜磨镶术3009眼的安全性和并发症发生率。方法：用飞秒激光制作角膜瓣，用博士伦H.Eye.Tech准分子激光系统进行准分子激光切割。对SBK术后并发症进行回顾性分析。结果：3009例SBK手术中，并发症发生率为0.63%。术中、术后皮瓣相关并发症发生率分别为0.33%和0.30%。仅1只眼(0.033%)因弥漫性板层角膜炎(DLK)失去一行最佳矫正视力。术中并发症包括皮瓣撕裂、游离帽、气泡脱出和瓣折叠。术后并发症包括DLK和上皮内生。其他与皮瓣有关的并发症，如凹凸不平的床面、纽扣孔、短皮瓣、皮瓣条纹或皱纹在本组中均未发生。所有术中并发症均在同一天内处理。结论：SBK术并发症发生率低。视力丧失也很少见。
PURPOSE: To assess the safety and complication rate of sub-Bowman's keratomileusis (SBK) in 3009 eyes.METHODS: The flaps were created using the IntraLase femtosecond laser, and excimer ablation was performed with the Bausch & Lomb H.Eye.Tech laser system. The complications of SBK were evaluated retrospectively. The types of complications were grouped into intra- and postoperative flap related.RESULTS: In 3009 SBK procedures, the total complication rate was 0.63%. Intra- and postoperative flap-related complication rates were 0.33% and 0.30%, respectively. Only 1 (0.033%) eye lost one line of best spectacle-corrected visual acuity from diffuse lamellar keratitis (DLK). Intraoperative complications included flap tear, free cap, bubble escape, and flap folds. Postoperative complications included DLK and epithelia[ ingrowth. Other flap-related complications such as uneven bed, buttonhole, short flap, flap striae, or wrinkles did not occur in this series. All intraoperative complications were managed within the same day.CONCLUSIONS: The complication rate of SBK is low. Vision loss is also rare.
