VISUAL SIMULATION USINGELECTROMAGNETIC ADAPTIVE-OPTICS

摘要

This study assessed the visual effects of correcting and modifying higher-order ocularwavefront aberrations in a group of subjects using an adaptive optics system based onelectromagnetic deformable mirror technology. The results showed that the correction ofhigher-order aberrations significantly improved visual performance compared to bestsphere and cylinder correction. The introduction of single Zernike aberrations of sameRMS magnitude and different mode numbers led to similar decreases in visual acuitywhen the applied aberration was relatively low (up to 0.3 μm). With larger amounts ofpure Zemike aberrations (0.9 μm), rotationally symmetric modes led to more pronounceddecreases in visual performance than non symmetric modes.
