PURPOSE
To report the results of the clinical use of single-piece acrylic intraocular lenses (IOLs; AcrySof(R), SA60AT, Alcon) compared with three-piece acrylic IOLs (AcrySof(R), MA60BM, Alcon) after cataract surgery. METHODS: We retrospectively analyzed data of the extent of IOL decentration and tilting measured with Scheimpflug camera (EAS-1000 anterior eye segment analysis system, Nidek) at 1 week, 1 month and 2 months after surgery, the difference in the preoperative predictive refraction and the postoperative actual refraction, and the higher order RMS (root mean square) value with WASCA wavefront analyzer (Carl Zeiss Meditec, Germany) between the two groups (SA60AT group: N=30 , MA60BM group: N=30). RESULTS: The extent of IOL decentration was statistically insignificant in both groups (p>0.05), but the amount of IOL tilting in the SA60AT group was significantly less than that in the MA60BM group at 1 week, 1 month and 2 months postoperatively (p<0.05). There was no statistically significant difference in the preoperative predictive refraction and the postoperative actual refraction between the two groups. The triangular coma aberrations and the higher order (HO) RMS values were, however, significantly less in the SA60AT group (p<0.05). CONCLUSIONS: The SA60AT IOLs provided a better postoperative centration and a smaller HO RMS value than the MA60BM IOLs. Based on these results, we expect that SA60AT IOLs will provide a better clinical outcome in the aspect of quality of vision. |
