To determine the rotational and centration stability of the Akreos AO aspheric intraocular lens (IOL) with orientation marks over the 6 months after implantation.
One hundred and seven patients across 6 European sites were implanted with the Akreos AO Aspheric IOL with orientation marks in one eye. At each visit (1-2 days, 7-14 days, 30-60 days; 120-180 days), the eyes were dilated and the IOL imaged at 10x magnification in retroilluminantion using a CSO SL-990 digital slit-lamp biomicroscope. The axis of rotation of the IOL was determined objectively by comparing the angle of the orientation marks on the IOL with two conjunctival vessels or iris features, consistent between sequential visits. The centration of the IOL was objectively measured as the calibrated difference between the centre of ovals overlaid to circumscribe the intraocular lens optic and the limbus.
The Akreos AO Aspheric intraocular lens with orientation marks is relatively stable in the eye over 6 months after implantation.
