中文摘要:

应用改进的Hartmann-Shack波前传感器人眼像差仪,测量了5只5.2 mm瞳孔的正常眼,向鼻侧和颞侧两个水平方向50°视场角Zernike第二级到第十级的波前像差.视场角从鼻侧和颞侧两个水平方向从0°增大到50°时,Zernike第三级波前像差的rms值平均增大2倍;Zernike第四级波前像差的rms值平均增大1.8倍;Zernike第五级到第十级波前像差的rms值平均增大1.7~1.3倍.

英文摘要:

Aberrations of the human eye as in the horizontal visual field were measured with modified Hartmann-Shack wave front sensor. The characteristic of third to tenth order Zernike aberration rms both temporally and nasally out to 50° is as follows: considerable differences occur among subjects in the pattern of aberrations, particularly for the dominating second-order aberrations; The third to tenth order Zernike aberrations increase with the visual angle,but the increscent magnitude decreases as the Zernike order increases;in despite of imperfect symmetry, the increscent magnitude is the same on the whole;the thirdorder Zernike aberrations increases up to 2 times from 0° to ±50° visual angle,the forth-order up to 1.8 times,and the fifth to tenth order up to 1.7~1.3 times.
