Abstract
The present invention relates to the field of devices for correcting or mitigating refractive errors in the eye, more particularly, to a solution in which desired improvements in eyesight are achieved as far as possible without limiting everyday activities and where performing the treatment itself involves minimum risk by use of a device for creating an aperture in an eye, the device having a control unit for a laser unit, and the control unit is designed to control the laser unit to create the aperture in a lens of the eye, wherein the aperture is used to increase the depth of field of the eye and is formed by laser-induced lesions which reduce light transmission through a lens aperture region surrounding an aperture opening.
