| 1. | The 1 mm spot corrects the higher order aberrations and fine tunes the treatment
1毫米点纠正较高的的顺序失常和精细地调节治疗。 |
| 2. | Nevertheless , different eyes have different visual outcomes like fingerprints , imperfections in the eyes which causes the image we somewhat blurry at night , that are defined as high order aberrations
因此，眼睛若带有微小瑕疵会使晚间视力模糊一点，这是由于高阶像差的存在所引致。 |
| 3. | Visx customvue wavescan aberrometer measures such high order aberrations , and then wavescan software translates this digital information to the laser system , driving a new level of precision and accuracy of lasik surgery
现在威视波前像差分析仪，能有效地量度高阶像差经计算并处理后传送到激光矫视仪器，使激光矫视手术的效果得到进一步提升。 |
| 4. | Higher order aberrations are widely believed by ophthalmic experts to contribute to common night vision problems , including glare and halos . the ladarwave customcornea system provides the precision capture you need for truly customized vision correction
但对于高阶像差high order aberration ，传统的激光矫视手术甚至是眼镜或隐形眼镜则显得束手无策。 |
| 5. | In addition to those vision problems you ve probably heard of before the lower order aberrations like nearsightedness and farsightedness there are common vision problems known as higher order aberrations that can also affect your vision
爱尔康角膜订定造系统ladarwave customcornea system传统的激光矫视手术能改善很多常见的视力问题，如近视远视及散光，亦即是低阶像差low order aberration 。 |
| 6. | Comparing to traditional refractive errors correcting , the principle and technique are quite different . basis on the concept of human eye wavefront aberration , chapter 4 studied zemike polynomials to represent the aberrated wavefront in the pupil and fitted the data to a zernike series to reconstruct the wavefront aberrations of living human eye . researched the relationship between second - order zernike coefficients and conventional spectacles . we verfied that wavefront aberration guided excimer laser cornea ablation surgery is feasibility and veracity , in order to provide theory foundation for correct the low order and the high order aberration of the human eyes
叙述了人眼像差的概念和产生的原因，并确定了采用zernike多项式表示像差的方法；首次定量分析了zernike多项式表示的像差与角膜切削深度的关系；首次采用主观式人眼像差仪测量像差，并研究了其实现原理和软件控制框图，论文首次研究了准分子激光进行矫正人眼像差的原理，为像差引导的准分子激光屈光手术提供了理论和实验依据，实现了“个性化切削” 。 |
