摘要
A system and method for correcting a vision defect (i.e. presbyopia) of a patient requires two laser units. A first laser unit is used to photoablate (i.e. remove) tissue from the cornea for the creation of a multi-focal cornea that simultaneously provides for both near and distance vision capabilities. A second laser unit can also be used to refine the shape of the cornea by weakening selected portions with LIOB. Together, the removal and weakening of corneal tissue are regulated to optimize the resultant near vision and distant vision capabilities of the patient.
