  • In this article, the individual intraocular lens in accordance with human visual characterists has been designed based on individual eye structure with optical design software ZEMAX, which can correct not only the defocus and astigmatism, but also the spherical aberrations by aspheric surface design. The power calculated from the individual intraocular lens is compered with that caculated from the experiential formula, showing an improvement of precision higher than 0.25D. The variation of the modulation and the resolution of human eye has been shown visually before and after the implantation of intraocular lens. The resolution has been improved from 28 L/mm to 118 L/mm, while the modulation has been improved from 0.02 to 0.51. The results show that the individual intraocular lens design has more accuracy, and the difference exists in correct effect because of the different optical properties of human eyes.
