摘要：Purpose
To evaluate postoperative spherical aberration, contrast sensitivity and depth of focus after implanting 3 different aspheric intraocular lenses.
Methods
Fifty-six eyes (18 eyes for Akreos adapt Advanced Optics (AO), 20 eyes for AcrySof IQ SN60WF and 18 eyes for Tecnis Acrylic IOL ZA9003) of 48 patients were evaluated. Internal ocular aberration including spherical aberration and higher-order aberration and contrast sensitivity were evaluated 3 months after lens implantation. In addition, visual acuities at 33 cm and 1 m distance were measured with the far vision corrected state to calculate depth of focus.
Results
The total and internal ocular spherical aberration of the AO implanted group was slightly higher than the other groups with statistical significance. However, there was no statistically significant difference of contrast sensitivity and depth of focus among the 3 groups.
Conclusions
A subtle difference of spherical aberration among the 3 groups without a statistically significant difference in other factors may not induce the differences of contrast sensitivities and depths of focus in each group.
