UNLABELLED
A minimally invasive keratorefractive procedure using high-intensity, low-energy femtosecond laser pulses to perform intrastromal ablation is described. Because of the low pulse energy and the ultrashort duration, tissue in the corneal stroma can be ablated with almost no heat or shockwave generation. This technique obviates the need for the laser in situ keratomileusis (LASIK) flap but retains the advantages of the LASIK procedure. In the technique, a series of femtosecond laser pulses create temporary microchannels in the stroma, oriented perpendicular to the eye's optical axis. After the microchannels are created, a second series of femtosecond pulses directly ablate the desired amount of stromal tissue in a controlled fashion. The ablated material is ejected from the microchannels so the surface layer above the ablated regions collapses, with a consequent change in the refractive power of the cornea.

描述了一种使用高强度、低能量飞秒激光脉冲进行基质内消融的微创角膜屈光手术。由于脉冲能量低且持续时间超短，角膜基质中的组织可以在几乎不产生热量或冲击波的情况下被消融。该技术无需制作准分子原位角膜磨镶术（LASIK）瓣，但保留了LASIK手术的优点。在该技术中，一系列飞秒激光脉冲在基质中创建与眼的光轴垂直的临时微通道。微通道创建后，第二系列飞秒脉冲以可控方式直接消融所需量的基质组织。被消融的物质从微通道中喷出，因此消融区域上方的表层塌陷，从而导致角膜屈光力发生变化。
