主客观结合测量眼像差的研究

he visual quality of human eye is not only limited by objective aberrations, but also suffers from neural processing and subjective perception, both objective and subjective method are needed for the measurement of human eye’s wavefront aberration. We have built an optical setup to integrate the two methods in a system. Then the result datum from both objective measurement and subjective measurement is fused on feature level by information fusion method with the weighting factors, which is helpful to emphasize the advantages of both subjective and objective measurement, can give more detailed advices for ideal corneal customized ablation of human eye.
