[Wavefront analysis in ophthalmologic diagnostics.] Ophthalmologe. 2008 Aug 30; Authors: Sanchez MJ, Mannsfeld A, Borkensein AF, Ehmer A, Limberger IJ, Holzer MP, Auffarth GU 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. PMID: 18758787 [PubMed - as supplied by publisher]
