DESCRIPTION (based on applicant's abstract): Given that the use of photorefractive keratectomy has been more successful in achieving accurate corrections for simple myopia than refractive keratotomy, FEO Medical proposed in Phase I studies to advance this approach. They developed a laboratory prototype that exploits a novel technique using a digital microelectromechanical system. It is comprised of several hundred thousand digitally controlled micromirrors to reflect excimer laser energy according to patterns obtained from digitally acquired corneal topography data. Experiments in Phase I showed that the mirrors could reflect enough energy to etch the cornea, using test materials. Corneal topography data was used to drive the micromirrors suggesting that the system could function in toto. During the Phase II project, FEO Medical plans to work with Texas Instruments, the manufacturer of the mircomirrors, to extend the life of the mirrors. They also plan to etch and analyze more complex topography patterns, to develop an eye tracking system, to develop a system to change the micromirror fixture easily, and to find a commercial company that would bring the system to market. FEO Medical states that they have a patent on the system as conceived, entitled High Resolution, High Speed, Programmable Laser Beam Modulating Apparatus for Microsurgery. PROPOSED COMMERCIAL APPLICATION: NOT AVAILABLE

描述（基于申请人摘要）： 鉴于屈光性角膜切除术的使用在以下方面更成功， 比屈光性角膜切开术对单纯性近视的矫正更准确， FEO Medical在I期研究中提出了推进这种方法。他们 开发了一个实验室原型，利用一种新的技术， 数字微机电系统它由几百个 上千个数控微镜反射准分子激光能量 根据从数字获取的角膜地形图数据获得的图案， 第一阶段的实验表明，镜子可以反射足够的能量， 使用测试材料蚀刻角膜。角膜地形图数据用于 驱动微镜，这表明该系统可以完全发挥作用。 在第二阶段项目中，FEO Medical计划与德州仪器合作， 镜子的制造商，以延长镜子的寿命。他们 还计划蚀刻和分析更复杂的地形图案，以开发 眼动追踪系统，开发一个系统，以改变固定装置 很容易，并找到一个商业公司，将该系统推向市场。 FEO医疗公司说，他们有一个专利的系统，作为设想，题为 高分辨率、高速、可编程激光束调制装置 显微手术。 拟议商业应用：不可用
