Astigmatic aberrations of the intraocular lenses (IOLs) within the central 5.2 and 3.0 mm optics. a The astigmatic aberrations of the X-60 and X-70 IOLs are not significantly changed within the central 5.2 mm optic diameter for extensions of 16 mm but the astigmatic aberrations of the X-60 IOL are significantly greater than that of X-70 IOL at an extension of 17 mm (n = 10). b The astigmatic aberrations of the X-60 and X-70 IOLs are not significant within the central 3.0 mm optic diameter. c The astigmatic aberrations of the VA-60BBR and VA-70 AD IOLs are not significant within the central 5.2 mm optic diameter. d The astigmatic aberrations of the VA-60BBR and VA-70 AD IOLs are not significantly changed within the central 3.0 mm optic diameter for extension up to 15 mm but the astigmatic aberrations of the VA-70 AD IOL are significantly greater than that of the VA-60BBR IOL from the extension of 16 mm. φ = central diameter measured with the wavefront analyzer, *; P < 0.05, Mann- Whitney U test
