Abstract
This invention is a method for sculpturing a laser beam ( ) in a predetermined pattern using a device ( ) between the laser source ( ) and the target ( ). The method comprises a series of sequential steps in which at least two regions of the cornea ( ) are each exposed to increasingly larger portions of the laser beam ( ). In the preferred embodiment, two pairs of complementary regions of the cornea ( ) will be sequentially exposed to laser radiation. In each such region, a first part will be exposed to a substantially segmental portion of the beam ( ), and then at least another larger substantially segmental portion of the beam ( ) in which the larger segmental portion, includes the smaller segmental portion. In the preferred embodiment, the target ( ) is the human eye, and the predetermined pattern is intended to shape the eye to treat it for astigmatism, myopia, or hyperopia.
