Book Description

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.

4 Imaging Method for LASIK Surgery



Over the last decade, the field of femtosecond eye surgery has expanded rapidly, combining high ablation precision and minimimal collateral tissue effects. One of the most promising applications for femtosecond laser eye surgery has been corneal surgery, namely LASIK surgery, where high-pressure laser plasma nonthermally dissociates the dense corneal tissue, thereby enabling lamellar cornea procedures with minimimal side effects and subsequently shaping the cornea surface with an excimer laser. Millions of patients worldwide have benefited from this new technology, and people have shown increasing interest in it and the research behind it.

LASIK surgery includes three parts: wavefront detection, femtosecond-laser flap creation, and excimer-laser cornea correction. This Spotlight focuses on femtosecond-laser-assisted LASIK surgery, including basic research for femtosecond-laser eye surgery and eye tissue imaging.
