Laser in situ keratomileusis (LASIK) surgery combines high-ablation precision and minimized collateral tissue effects to nonthermally dissociate dense corneal tissue. The procedure has benefited millions of patients and sparked increased interest in the principles and research behind it. This Spotlight discusses femtosecond-laser-assisted LASIK surgery and its three primary components: wavefront detection, femtosecond-laser flap creation, and excimer-laser cornea correction.
Over the last decade, the field of femtosecond eye surgery has expanded rapidly, supporting the advantages of combined high-ablation precision and minimized collateral tissue effects. One of the most promising applications for femtosecond laser eye surgery has been corneal surgery, namely laser in situ keratomileusis (LASIK) surgery, where the high-pressure laser plasma nonthermally dissociates the dense corneal tissue thereby enabling lamellar cornea procedures with minimized side effects and the subsequent excimer laser shapes the corneal surface. Millions of people worldwide have been patients for LASIK surgery and have benefited from such new technology. Recently, people have shown increasing interest in this surgery itself and the research behind it. LASIK surgery includes three parts: wavefront detection, femtosecond-laser flap creation, and excimerlaser cornea correction. This Spotlight focuses on femtosecond-laser-assisted LASIK surgery, including basic research for femtosecond-laser eye surgery and tissue imaging.
