To compare high-order aberrations in the pseudophakia with different types of intraocular lenses (IOLs), as well as with normal phakic eyes. METHODS: This single-center prospective study comprised 80 cataract patients who underwent cataract surgery and 20 phakic eyes. Twenty eyes received an AF-1(R) VA-60BB; 20 eyes, a Corneal(R) ACR6D SE; 20 eyes, a Sensar(R) AR40e; and 20 eyes, a ClariFlex(R). One month after cataract surgery, the eye aberration was measured using a Hartmann-Shack type aberrometer. The same test was performed for 20 normal phakic eyes. The individual Zernike polynomials, the root mean square (RMS) values of the third and fourth order aberration, and the total RMS among the groups were compared. RESULTS: The individual Zernike coefficient (Z3(-1), Z3(3), Z4(-4), Z4(0), Z4(4)) showed a significant difference in the IOL-implanted groups compared with the normal phakic eyes. There were statistically significant differences in the RMS values of the third and fourth order aberration, and total among each group. CONCLUSIONS: There was a statistically significant increase in aberration in patients with high refractive index IOL and a statistically significant decrease in patients with silicone IOL, compared to the normal phakic eyes.
