PURPOSE
To assess the clinical results of various acrylic intraocular lenses (IOLs) after cataract surgery with respect to the tilting and decentration of IOLs, postoperative high-order (HO) aberration, and duration to gain of refractive stability. METHODS: This prospective study comprised 60 eyes of 53 patients after uneventful cataract surgery with IOLs implantation. Patients were randomized into four groups of 15 eyes each based on IOLs type: MA60BM, SA60AT, AR40e, or Akreos. We analyzed the extent of IOL decentration, tilting and the difference between preoperative predictive refraction and postoperative actual refraction at 1 day, 1 week, 1 month and 2 months after surgery. The postoperative HO aberration was determined at 2 months after surgery. RESULTS The extent of IOL decentration and tilting was not statistically significant among any of the groups (p>0.05). The spherical aberrations, the triangular coma aberrations and HO RMS values were, however, statistically significantly different among the groups (p<0.05). Refractive stability was gained by 2 months in all four groups, but the four IOLs differed in the time to refractive stability: 2 months in the MA60BM group, 1 month in the SA60AT group, 1 day in the AR40e group, and 1 week in the Akreos Adapt group. CONCLUSIONS: All four acrylic IOLs provided satisfactory postoperative results, but there were differences in the time to gain of refractive stability and HO aberration between the four IOLs. These results suggest that a surgeon could achieve a better clinical outcome after cataract surgery by selecting the most suitable IOL for his intention. |
