    • In an ophthalmic laser system preferably intended for photoablative refractive surgery, a component apparatus that is preferably an optical coherence tomography device for measuring corneal pachymetry makes its measurement when the First and Second Purkinje reflections of the OCT probe beam are detected, otherwise, the reflection signal is not strong enough to enable the OCT measurement. The beam axis of the therapeutic laser of the system is co-aligned with the OCT- prbbe beam. When the First and Second Purkinje reflections of the OCT probe beam are detected, a signal is generated by the OCT device and sent to the eye tracker component of the system to engage the eye tracker operation. This allows for objective, automatic engagement of the eye tracker and alignment of the patient's optical axis to the treatment axis or a diagnostic beam axis.
    • 在优选用于光烧伤性屈光手术的眼科激光系统中,优选地,用于测量角膜厚度测量的光学相干断层摄影装置的分量装置在检测到OCT探针光束的第一和第二浦肯野反射时进行测量,否则,反射信号 不够强大,不能进行OCT测量。 系统的治疗激光束的光束轴与OCT-prbbe光束共同对准。 当检测到OCT探测光束的第一次和第二次浦肯野反射时,由OCT装置产生信号并将其发送到系统的眼睛跟踪器部件以进行眼动仪操作。 这允许眼睛跟踪器的客观的自动接合和患者的光轴对准治疗轴或诊断光束轴。

    • This invention is directed to a method for providing a LASIK or a LASEK myopia vision correction, and to a medium that has stored therein an instruction for directing a laser vision correcting laser platform to deliver a controlled biodynamic ablation according to the invention. A known biodynamic response of the eye is induced by performing a controlled laser ablation in a cornea of the eye outside of an optical zone for the nominal ablation in a laser vision correction surgery. An ablation ring, or portion thereof, outside of the optical zone produces a biodynamic flattening of the central region of the cornea which in turn provides for a decreased depth of volumetric ablation to correct a myopic refractive defect of the eye. Such controlled biodynamic flattening may provide the opportunity for laser vision correction in patients whose corneas would otherwise be too thin post-operatively to warrant laser vision correction.
    • 本发明涉及一种用于提供LASIK或LASEK近视视力矫正的方法,以及存储有根据本发明的用于引导激光视力矫正激光平台传送受控生物动力学消融的指令的介质。 通过在激光视力矫正手术中的用于标称消融的光学区域外部的眼睛的角膜中进行受控激光烧蚀来诱导眼睛的已知生物动力学响应。 在光学区域外部的消融环或其部分产生角膜中心区域的生物动力学平坦化,其进而降低体积消融的深度以校正眼睛的近视屈光不良。 这种受控的生物动力学平整可以为患者提供激光视力矫正的机会,其角膜否则在手术后会太薄,以保证激光视力矫正。
