Embodiment
[0025] Embodiment: a kind of scanning method of ablation corneal tissue comprises the following steps:
[0026] The first stage: the computer calculates the total number of points to be ablated to be ablated through the scanner, obtains the coordinates of each point to be ablated, and then divides the coordinate points into scanning areas, and the number of scanning points in each scanning area is the same.
[0027] The division of the scanning area: firstly, the computer divides all the calculated points a into n parts according to the spot parameters, and marks them as Ⅰ, Ⅱ, Ⅲ, Ⅳ...the remaining parts are assigned to the first few scans in order area, so that the number of scan points for each scan area is obtained. According to the abscissa x of the scanning points (perpendicular to the wind direction), they are arranged in ascending order, and the corresponding number of scanning points are counted in order as the first area, and the abscissa of the boundary line of the sc...
