如何做好波前像差引导的准分子激光角膜原位磨镶术

在诸多的个体化手术中，波前像差引导的准分子激光角膜原位磨镶术（LASIK）不仅可以提高术后裸眼视力和矫正视力，也能在一定程度上减少术后高阶像差的增加幅度，改善夜间视力，降低眩光和光晕的发生率，提高对比敏感度。主要阐述以下几个问题的观点：（1）如何理解波前像差对LASIK术后视觉质量的影响？（2）如何正确获得波前像差的检测数据，筛选手术适应证？（3）如何界定波前像差引导的LASIK手术设计的金标准？（4）如何将波前像差检查的数据转化为最优化的手术设计方案？（5）手术执行过程中需注意哪些问题？（6）波前像差引导的LASIK应该达到怎样的术后效果？

How to make the wavefront-guided laser in situ keratomileusis better

Wavefront-guided laser in situ keratomileusis （LASIK） is onekind of the customized surgeries. It not only can increase the postoperative uncorrected visual acuity （UCVA） and best corrected visual acuity （BCVA） , but also can lessen the increase of the higher-order aberration. Meanwhile,wavefront-guided LASIK can improve the scotopic vision,decrease the incidence of the glare and halo and enhance contrast sensitivity （CS）. This subject focus on the problems as follows： （1） How to understand the affection that wavefront aberration made on the visual quality after LASIK？ （2） How to get the wavefront measurements accurately and choose the surgery adaptation？ （3） How to ascertain the gold standard to design the wavefront-guided LASIK？ （4） How to transform the wavefront measurements into the optimized surgery scheme？ （5） What problems should be paid attention to during the surgery？ （6） What results the wavefront-guided LASIK should attain？
