AIM:To investigate the related factors in the ocular aberrations induced by myopia. METHODS:The ocular aberrations of 115 cases ( 218 eyes ) were measured before laer in situ keratomileusis (LASIK) refractive surgery in our hospital by Zywave. Preoperative examinations included contrast sensitivity and wavefront aberrations for both eyes by Zywave (Hartmann-Shack wavefront aberrometer). RESULTS:About 89% of all in ametropia people was low order wavefront aberration (defocus and regular astigmatism),and 3^rd order and above were only about 11%, Individual difference was large in high order aberrations from 1.86 to 0.03.RMS was increased with the larger pupil zone. The correlations between the components of wavefront and contrast sensitivity were weak negative.There were no correlations between the RMS of high order aberration and diopter in eyes with myopic spherical errors below -6.00D, whereas in eyes with errors between -6.00D and -14.00D,the correlations were stronger.The RMS of 3^rd and 4^th order aberration were positively correlated with astigmatism. There was no obvious difference between female and male. CONCLUSION:Wavefront aberration of the myopia patients is affected by specific conditions, personalized surgical removal of the wavefront aberration should be thoughtful."
