摘要：This invention is a method for sculpturing a laser beam (13) in a predeterminedpattern using a device (17) between the laser source (11) and the target (23). The methodcomprises a series of sequential steps in which at least two regions of the cornea (177)are each exposed to increasingly larger portions of the laser beam (13). In the preferredembodiment, two pairs of complimentary regions of the cornea (177) will be sequentiallyexposed to laser radiation. In each such region, a first part will be exposed to asubstantially segmental portion of the beam (13), and then at least another largersubstantially segmental portion of the beam (13) in which the larger segmental portion,includes the smaller segmental portion. In the preferred embodiment, the target (23) isthe human eye, and the predetermined pattern is intended to shape the eye to treat itfor astigmatism, myopia, or hyperopia.
