Claim 0:
1. A method for creating lenticular incisions in a corneal stroma of a patient to correct low hyperopia and/or myopia, the method comprising:
placing a patient interface device in contact with a cornea of the patient's eye to applanate the cornea;
calculating an initial top lenticular shape and an initial bottom lenticular shape in the applanated cornea, wherein the initial top lenticular shape and the initial bottom lenticular shape define an initial space between them, and calculating a shape of an added space in the applanated cornea, wherein the initial top lenticular shape and the initial bottom lenticular shape are calculated based on a predetermined correction power, wherein the shape of the added space is calculated based on the predetermined correction power, and wherein the shape of the added space introduces zero correction power in the cornea in an unapplanated state;
calculating a top lenticular incision shape in the applanated cornea based on the initial top lenticular shape and the shape of the added space, and a bottom lenticular incision shape in the applanated cornea based on the initial bottom lenticular shape and the shape of the added space;
using a pulsed femtosecond pulsed laser beam for incising, in the stroma of the applanated cornea,
a top lenticular incision having the calculated top lenticular incision shape;
a bottom lenticular incision having the calculated bottom lenticular incision shape;
and
a transition ring incision intersecting both the top lenticular incision and the bottom lenticular incision; and

removing the patient interface device from the cornea to return the cornea to the unapplanated state.
