operating the ophthalmic surgical laser system to form a bottom lenticule surface incision in the cornea,
wherein the top and bottom lenticule surface incisions intersect each other to form an isolated volume of corneal tissue between them, the isolated volume of corneal tissue being isolated from remaining portions of the cornea, and
wherein the isolated volume of corneal tissue includes a lenticular portion having a circular or oval shape in a top view, and a side tab portion connected to the lenticular portion and protrudes from a peripheral location of the lenticular portion, wherein the side tab portion has a defined thickness profile in a side cross-sectional view; and extracting the isolated volume of corneal tissue from the patient's eye, whereby the vision of the patient's eye is corrected.
