    • A laser beam ophthalmological surgery method for ablating a cornea (16) of a patient's eye includes the steps of generating a laser beam (12) and directing the generated laser beam onto a scanner (13) and scanning the laser beam (12) in a random scanning pattern with a generated random scanning pattern signal on the surface of the cornea (16) of a patient to ablate the surface of the cornea of a patient's eye. A computer (17) generates the random pattern laser beam control signal which controls the scanner (13) to scan in the random scanning pattern over the cornea (16) and includes selecting a database of non-random scanning points to scan the laser beam onto the cornea (16) of a patient's eye and then randomly selects the non-random scanning points for the random scanning of predetermined scanning points. A laser ophthalmological surgery apparatus (10) is provided which includes a laser (11) for generating a laser beam (12) along with a scanner (13) positioned for receiving the laser beam (12) and producing a predetermined scanning pattern onto the cornea (16) of an eye. A computer (17) is used to generate a random scanning pattern signal and is connected to the scanner (13) for controlling the scanner in a random overlapping scanning beam pattern over a predetermined area.
    • 一种用于消除患者眼睛角膜(16)的激光束眼科手术方法包括以下步骤:产生激光束(12)并将所产生的激光束引导到扫描器(13)上并且将激光束(12)扫描在扫描仪 随机扫描图案,其具有在患者的角膜(16)的表面上产生的随机扫描图案信号,以消除患者眼睛的角膜的表面。 计算机(17)产生随机图案激光束控制信号,其控制扫描仪(13)以随机扫描图案扫描角膜(16),并且包括选择非随机扫描点的数据库以将激光束扫描到 然后随机选择用于随机扫描预定扫描点的非随机扫描点的患者眼睛的角膜(16)。 提供了一种激光眼科手术设备(10),其包括用于产生激光束(12)的激光器(11),以及定位成用于接收激光束(12)的扫描器(13)并且产生预定的扫描图案到角膜 (16)眼睛。 计算机(17)用于产生随机扫描图案信号,并连接到扫描仪(13),用于在预定区域上以随机重叠的扫描光束图案控制扫描仪。
