PURPOSE OF REVIEW
The femtosecond laser has potentially improved the safety and precision of creating corneal flaps in laser in situ keratomileusis (LASIK). This review focuses on recent advances in applying femtosecond laser technology to other corneal procedures.
RECENT FINDINGS
The femtosecond laser is capable of cutting tissue at various depths and patterns with minimal collateral tissue injury. The laser can now be used to perform corneal pockets for ring segments, arcuate wedge-shaped resection in correction of high astigmatism, lamellar dissections in anterior lamellar keratoplasty, donor tissue preparation in Descemet's stripping endothelial keratoplasty, and shaped full-thickness keratoplasty.
SUMMARY
Femtosecond laser-assisted corneal surgery may provide a more precise and safer approach to corneal surgery.
综述目的
飞秒激光有可能提高准分子原位角膜磨镶术（LASIK）中制作角膜瓣的安全性和精确性。本综述聚焦于飞秒激光技术在其他角膜手术应用方面的最新进展。
最新发现
飞秒激光能够以最小的周边组织损伤在不同深度和模式下切割组织。目前该激光可用于制作角膜袋以植入角膜环、进行弧形楔形切除术以矫正高度散光、在前板层角膜移植术中进行板层剥离、在Descemet膜剥脱内皮角膜移植术中制备供体组织以及进行塑形全层角膜移植术。
总结
飞秒激光辅助角膜手术可能为角膜手术提供一种更精确、更安全的方法。
