PURPOSE
To evaluate preoperative and postoperative spherical aberrations after cataract surgery based on selecting spherical or aspheric intraocular lens (IOL) according to preoperative corneal aberration. METHODS: The medical records of patients who underwent phacoemulsification and IOL implantation in the posterior chamber by a surgeon (H.J.C) were reviewed (68 patients, 97 eyes). IOL was selected based on preoperative corneal spherical aberration measured by corneal topography (ATLAS 9000, Carl Zeiss). The target postoperative total ocular spherical aberration was set to zero (0) and one of the following lenses was chosen: Acrysof SA60AT (n = 25), Acrysof IQ (n = 36) or Tecnis(R) ZCB00 (n = 36). The Wavescan aberrometer and the corneal topography were obtained postoperatively. Absolute prediction errors of postoperative total ocular spherical aberration were analyzed. RESULTS: Preoperative corneal spherical aberration was 0.241 microm; total postoperative ocular spherical aberration was 0.0509 microm (Acrysof SA60AT: 0.0954 microm, Tecnis(R) ZCB00: 0.0374 microm, Acrysof IQ: 0.0335 microm). Postoperative corneal spherical aberration was 0.232 microm, which was not significantly different from the preoperative value (p = 0.199). Postoperative ocular spherical aberration was 0.051 microm; 0.095 microm (Acrysof SA60AT), 0.034 microm (Acrysof IQ), and 0.037 microm (ZCB00). The reducing amounts of spherical aberration were 0.185 microm (Acrysof IQ) and 0.311 microm (ZCB00). The overall absolute prediction error was 0.068 microm. The absolute prediction error of the Acrysof SA60AT group was 0.092 microm, Tecnis(R) ZCB00 group was 0.067 microm and Acrysof IQ group was 0.054 microm. There was no significant difference among the 3 groups (p = 0.089). CONCLUSIONS: Aspheric IOLs can efficiently reduce total ocular spherical aberrations according to preoperative corneal spherical aberrations. |
