Abstract

PURPOSE
To compare the aberration change in the pseudophakia with three types of acrylic intraocular lenses (IOL) as well as with normal phakic eyes METHODS: This single-center prospective study comprised of 51 cataract patients who underwent cataract surgery and 12 phakic eyes. Fourteen eyes received an Acrysof(R) MA60BM, 18 eyes, a Sensar(R) AR40, and 19 eyes, an Corneal(R) ACR6D. One month after cataract surgery, the aberration of the eyes was measured using a Hartmann-Shack type aberrometer. The same test was performed for 12 normal phakic eyes. The individual Zernike polynomials, and the root mean square (RMS) values of the third and the fourth order aberration among the groups were compared. The total RMS value of each group was also compared. RESULTS: The RMS value of the third and the fourth order aberration was similar in each group. In addition, there was no significant difference in the total RMS value among the groups. An individual Zernike coefficient (Z3(3); triangular astigmatism with a base on the y axis) showed a significant difference in all the IOL implanted groups compared to the normal phakic eyes. CONCLUSIONS: An ocular higher-order aberration after these 3 acrylic IOL implantations in cataract surgery is similar to that of the normal phakic eyes, but can differ in the local aberration.
