Comparison of Long-Term Results between One-piece and Three-piece Acrylate Intraocular Lens

`Purpose: To compare the long-term clinical results of one-piece Acrysof? (SA60AT) hydrophobic acrylic intraocular lens (IOL) implantation compared with implantation of three-piece Acrysof? (MA60BM) hydrophobic acrylic IOL. Methods: We retrospectively analyzed each 50 eyes of 50 patients underwent MA60BM or SA60AT IOL implantation and followed for at least 6 months. Results: Final visual acuity of 0.5 or better was 38 eyes (76%) and 0.8 or better was 20 eyes (40%) in the SA60AT group. In the MA60BM group, it was 41 eyes (82%) and 23 eyes (46%) respectively. There were no significantly differences in predictability, intraocular pressure, endothelial cell density, astigmatism, and incidence of posterior capsule opacification between the two groups. Spherical equivalent at postoperative 1 week was -0.50±0.95D in SA60AT group and was -0.31±0.88D in MA60BM group (P=0.04). However, there was no significant difference between the two groups during follow up period. In MA60BM group, anterior chamber depth (P=0.02) and distance between iris and IOL (P=0.04) reduced significantly during the first postoperative month. Conclusions: Early postoperative axial displacement and changes in spherical equivalent can be occurred in MA60BM group. However there was no difference in long-term clinical results between SA60AT and MA60BM groups. `
