The study of objective wavefront aberration measurement of human eyes

The mechanism of the production of the aberration in the human eyes and the ways to describe them were analysed according to wave optics theory.The mathematical function of wavefront aberration expressed by Zernike polynomial is analysed,and the relationship between Zernike polynomials and wavefront aberrations and the influence of wavefront aberration of single Zernike modes on optical quality are emphasized.Afterwards the resolved scheme of the measurement of the eye wavefront aberrations was proposed by the use of the Hartmann-Shack wavefront sensor and deformable mirrors are used as wavefront aberrations correctors respectively,which are involved with the theory of the wavefront reconstruction by the use of the Zernike polynomials in the adaptive optics.It has important experimental and clinical value for improving vision of normal human eyes and correcting operation of diopter.
