Modern aberrometry measures standard and so-called higher-order refractory aberrations. Ophthalmology and optometry use Zernike polynomials to describe aberrations of the retina and lens causing refractory errors. Aberrations of a higher order sometimes follow successful laser surgery, causing reduced vision and inducing patient dissatisfaction; enhanced wavefront data can help to avoid this. Aberrometry is used also for objective measurement of refractory changes. Wavefront techniques and their clinical application enable many options for understanding the delicate balance of eye optics. The future of refractive surgery lies in increasingly individualized treatment to suppress higher degrees of aberration and thus improve clinical results. Patients will continue placing greater demand on individualized intraocular lenses that correct higher-order aberrations.
现代像差仪可测量标准像差以及所谓的高阶屈光像差。眼科和验光领域使用泽尼克多项式来描述导致屈光不正的视网膜和晶状体像差。高阶像差有时会在成功的激光手术后出现，导致视力下降并引起患者不满；增强的波前数据有助于避免这种情况。像差仪还用于客观测量屈光变化。波前技术及其临床应用为理解眼屈光的微妙平衡提供了多种选择。屈光手术的未来在于越来越个性化的治疗，以抑制更高程度的像差，从而改善临床效果。患者将继续对能够矫正高阶像差的个性化人工晶状体提出更高要求。
