    • An aperture card is provided for insertion into a laser refractive ablation system for use in laser ablating the cornea. The aperture card is designed for single surgical use for surgical precautionary considerations and to achieve the highest quality ablations, in addition to reproducibility. The aperture card is loaded into the laser refractive ablation system in a path between the laser system and the eye. The aperture card is precisely located by positioning means and ablative lasing action is inhibited if the card is not positioned within tolerance. Alternatively, the laser system can determine the position of the aperture card and adjust a computed ablation profile or otherwise adjust the optical system to adapt for any misalignment of the apertures in the aperture card. The card contains a “soft spot” aperture capable of shaping a spatial intensity distribution with a unique profile. The profile has a substantially flat top while the sides of the profile slope until an ablation intensity threshold is reached, at which point the sides become substantially vertical. The card can contain more than one soft spot aperture along with a “hard spot” aperture that creates a square-shaped profile used for testing fluence. Each soft spot aperture is formed by a central aperture and a plurality of holes of different sizes surrounding the central aperture and arranged such that the overall diffractive effect produces a soft spot spatial intensity profile compared to the hard, square-sided profile.
    • 提供孔卡用于插入到用于激光烧蚀角膜的激光折射消融系统中。 孔卡被设计用于单次外科手术用于手术预防性考虑,并且除了重现性之外还实现了最高质量的消融。 孔径卡在激光系统和眼睛之间的路径中被加载到激光折射消融系统中。 光圈卡通过定位装置精确定位,如果卡未位于公差范围内,则禁止​​消融激光作用。 或者,激光系统可以确定光圈卡的位置并调整计算的切割轮廓,或者调整光学系统以适应孔径卡中的孔的任何未对准。 该卡包含一个能够形成具有独特轮廓的空间强度分布的“软点”孔。 轮廓具有基本上平坦的顶部,而轮廓的侧面倾斜直到达到消融强度阈值,此时侧面基本上垂直。 该卡可以包含多个软点孔径以及一个“硬点”孔径,创建用于测试注量的方形轮廓。 每个软点孔由围绕中心孔的中心孔和不同尺寸的多个孔形成,并且布置成使得与硬的正方形轮廓相比,整体衍射效应产生软斑空间强度分布。

    • A method and business architecture for providing vision correction to a patient involves obtaining wavefront aberration measurement information and, optionally, patient history data, ordering data, dispensing data, billing data, and other information, from the patient; transmitting the various data to respective appropriate platforms, e.g., transmitting the wavefront aberration information to a custom lens supply platform; producing a custom lens for the patient; and delivering a custom lens to the patient in a personalized manner. The method further involves fitting and measurement processes including in-situ lens shaping and custom manufacture of contact lenses, IOLs, inlays or onlays by laser ablation, lathing, casting/molding and machining. Business architectures according to the invention include segregating vision correction method steps into contractual, revenue generating business transactions.
    • 用于向患者提供视力矫正的方法和业务架构包括从患者获得波前像差测量信息和可选地获得患者病史数据,排序数据,分配数据,记帐数据和其他信息; 将各种数据传送到相应的适当的平台,例如将波前像差信息传送到定制的镜头供应平台; 为患者生产定制镜片; 并以个性化的方式向患者提供定制镜片。 该方法还涉及包括原位透镜成形和定制制造隐形眼镜,IOL,嵌体或嵌体的激光烧蚀,车床,铸造/模制和机加工的装配和测量过程。 根据本发明的业务架构包括将视觉校正方法步骤分离成合同的创收业务交易。
