Abstract: The increase of the depth of focus (DOF) for the treatment of presbyopia or cataracts is a topic of great interest for anterior segment surgeons that have seen how new surgical possibilities to achieve DOF enlargement have emerged. Nowadays, several technologies to extend the DOF are available, from corneal laser refractive surgery (LRS) procedures in presbyopia to intraocular lens (IOL) implantation in cataract or refractive lens exchange. Some of these procedures are based on aspherical profiles, either in the cornea or in the IOL, which modulate the spherical aberration (SA) and therefore extend the light energy on different focal planes.
