PURPOSE:To study the correlation between corneal wavefront changes induced by cataract surgery and ocular aberration in AsphericIOL eyes.METHODS:48 eyes with AcrySof IQ IOL implant were included.Corneal aberrations were measured pre-and 3-6 months postoperatively and total ocular aberrations were measured postsurgery.Surgical induced corneal aberrations was calculated and correlated to the ocular wavefront.RESULTS:Significant changes of corneal aberration were found after surgery.Terms of surgical induced corneal aberration varied individually.Statistically significant correlations were found between corneal aberration and total aberration from 2-nd to 6-th aberrations in 13 terms.When considering the relation of surgical induced corneal aberration and ocular aberration,five terms(C16,C18,C20,C21,C23)showed significant correlation.CONCLUSIONS:2.2 mm microincision coaxial phacoemulsification can induced optical changes in anterior cornea.The distortions of the cornea do have a role on the total ocular aberration in patients with aspheric IOL.
