To study the wavefront aberration of patients with multi-focal IOL implantation and evaluate the imaging quality of IOL, fifty-nine eyes of 56 patients undergoing cataract surgery are collected, including 24 eyes in the multi-focus intraocular lens group and 35 eyes in the single-focus intraocular lens group. The two groups of patients are implanted with Diffractiva-aA multi-focus intraocular lens or Aspira-Aay single-focus intraocular lens, respectively. The wavefront aberration of the operative eye was measured by VISX WaveScan wavefront aberration meter one month after surgery. The results of the two groups of measurement data were compared. The results showed that the total aberration of the multi-focus intraocular lens group and the single-focus intraocular lens group were 1.13±0.19μm and 0.92±0.26μm (F= 0.975, P=0.001) respectively, and the difference was statistically significant. The total high-order aberrations in the multi-focus IOL group were higher than those in the single-focus IOL group, 0.61±0.13μm and 0.38±0.10μm, (F= 0.963, P=0.000), respectively, and the difference was statistically significant. The spherical difference in the multi-focus IOL group was higher than that in the single-focus IOL group, 0.26±0.12μm and 0.16±0.094 μm (F=1.239, P=0.001), respectively, and the difference was statistically significant. Therefore, we conclude that multi-focus intraocular lens can provide patients with better far and near vision after surgery, but higher order aberrations are increased compared with single-focus intraocular lens, which has a negative impact on imaging quality.
