Retinal image contrast and functional visual performance with aspheric, silicone, and acrylic intraocular lenses

All 3 IOLs led to improved visual acuity after cataract surgery. The aspheric IOL provided a significant improvement in retinal image contrast and visual performance measured by visual acuity and functional acuity contrast testing. This improvement was greatest in night vision and night vision with glare compared to the performance of conventional spherical silicone and acrylic IOLs.
