英文摘要: This research studied the dynamic aberration of human eyes at near vision. A wavefront aberrometer was developed based on the Hartmann-Shack theory. This aberrometer can achieve dynamical aberration measurement of the human eye. The Aberrometer induces ocular accommodation by a moving target at near vision, and records the vision information of human eyes simultaneously during ocular accommodation process using a Hartmann-Shack sensor. Nineteen eyes of 10 volunteers are tested. Eighty-four percent eyes have induced accommodation amplitude between 3 diopter (D) and 8D. The highest induced accommodation amplitude is 8.6D. The aberrometer produces results with high precision and repeatability, i.e. an accuracy root-mean-square (RMS) of 1/50(lambda) and a repeatability RMS of 1/500(lambda). (C) 2009 Elsevier GmbH.
