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.
Conclusion : 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.
