To evaluate the differences between various intraocular lens (IOL)s in refractive change and anterior shift of the IOL after cataract surgery. Postoperative refractive change was analyzed 1 week to 12 months after cataract surgery using an autorefractmeter in 4 patient groups implanted with 811 C (HSM-PMMA, 83 eyes), 824 C (HSM-PMMA, 80 eyes), AQ 110 NV (3-piece silicone, 191 eyes), and MA 60 BM (3-piece acrylic, 80 eyes). Anterior-posterior shift of an IOL after surgery was studied using an anterior segment analyzer (EAS-1000) in 2 groups (824 C and AQ 110 NV). Refractive change after YAG laser posterior capsulotomy was also evaluated in 2 groups (811 C RESULTS: Only the AQ 110 NV group demonstrated statistically significant myopic change, which gradually increased until 12 months after cataract surgery, and significant anterior shift of an IOL 3 months after surgery. Significant refractive change was not observed after YAG capsulotomy. A silicone IOL (AQ 110 NV), but not HSM-PMMA or acrylic IOL, shifted anteriorly, resulting in myopic change after cataract surgery.
