Abstract
Purpose: To evaluate the postoperative outcome of Tecnis? ZCB00 1-Piece acrylic intraocular lens (IOL), the new single piece, aspheric IOL until 12 months.

Methods: Sixty eyes undergone cataract surgery using two different IOLs; The Tecnis? ZCB00 1-Piece Acrylic IOL (30 eyes) and the Tecnis? ZA9003 3-Piece Acrylic IOL (30 eyes). Cataract surgery was performed in the same period. All complicated cases were excluded. Best corrected visual acuity (BCVA), refractive error, photopic and mesopic contrast sensitivity, total high order aberration, spherical aberration and anterior chamber depth were measured preoperatively and at 1, 6 and 12 months after surgery.

Results: There were no statistically significant differences between two groups in BCVA, refractive error, total high order aberration and spherical aberration all the time after surgery. Both groups have negative ocular spherical aberration until 12 months after surgery. 1-piece and 3-piece groups had different tendency in axial movement. But there were no statistically significant differences in anterior chamber depth measured at 1 week, 1, 6 and 12 months after surgery. There was no statistically significant difference in contrast sensitivity at 1, 6 and 12 months after surgery.

Conclusions: The Tecnis? ZCB00 1-Piece acrylic intraocular lens (IOL) showed comparable clinical outcomes to the Tecnis? ZA9003 3-Piece acrylic intraocular lens (IOL) until 12 months after cataract surgery. 1-piece and 3-piece IOL group had different tendency in axial movement. However, refraction remained stable during 12 months after surgery. Mostly, both IOL groups had negative ocular spherical aberration during whole follow-up period.
