1. A treatment apparatus for surgical correction of hyperopia in an eye having an axis of vision, the treatment apparatus comprising:
a laser device including a laser and scanners, the scanners each comprising mirrors, optics or a combination of mirrors and optics, the laser device being controlled by a controller and the laser device separating corneal tissue by applying laser radiation;
the controller being programmed with an algorithm that controls the laser device including the laser and the scanners to emit the laser radiation into the cornea at a focus positioned by operation of the laser and the scanners wherein a lenticular volume is isolated in the cornea, the lenticular volume being structured such that removal of the lenticular volume effects a desired correction of hyperopia;
the controller further being programmed with an algorithm that controls the laser and the scanners to define the lenticular volume to have a posterior face and an anterior face and an edge face connecting the posterior face with the anterior face; and
the edge face when viewed in cross section having first and second linear portions, wherein the second linear portion is located more posterior than the first linear portion and is inclined more inwardly to the axis of vision than the first linear portion when viewed from anterior to posterior.
