Coma aberrations within the central 5.2 and 3.0 mm diameter of the intraocular lenses (IOLs). a The coma aberrations of the X-60 and X-70 IOLs are not significantly changed within the central 5.2 mm optic diameter for extensions up to 16 mm but the coma aberrations of the X-70 IOL are significantly greater than that of the X-60 IOL at an extension of 17 mm (n = 10). b The coma aberrations of the X-60 and X-70 IOLs are not significantly changed for the central 3.0 mm optic diameter for an extension of 14 mm but the coma aberrations of X-60 IOL are significantly greater than that of the X-70 IOL for an extension of 15 mm. c The coma aberrations of the VA-60BBR and VA-70 AD IOLs are not significant within the central 5.2 mm diameter. d The coma aberrations of the VA-70 AD IOLs within the central 3.0 mm diameter are significantly greater than that of the VA-60BBR IOL at the extension of 14, 16, and 17 mm. φ = central diameter measured with the wavefront analyzer, *; P < 0.05, Mann- Whitney U test
