Abstract

This paper introduces a new field in laser vision surgery: therapeutic wavefront surgery. Therapeutic wavefront surgery, rather than correcting a specific prescription, is used to correct visual quality problems – and particularly night vision and contrast problems — induced by older generation LASIK and PRK. This paper examines how night vision problems after LASIK are typically caused by the induction of spherical aberration close to the optical axis. Wavefront technology can be harnessed to map – and ultimately treat – these aberrations induced by older generation lasers. In this way, visual quality problems such as night vision complaints can be directly treated, even in patients who otherwise no longer have nearsightedness, farsightedness, or astigmatism after their previous surgery.
