This document discusses the development of new ablation profiles for treating very high myopia using LASIK. It describes how early profiles induced spherical aberration and night vision disturbances. The author developed profiles that use larger optical zones and incorporate asphericity to reduce aberrations. Challenges included controlling spherical aberration induction and limiting flap thickness. New hybrid aspheric profiles and femtosecond lasers allow treating higher levels of myopia with good accuracy and low rates of side effects like night vision disturbances.
