The Theory and Clinical Research of Aspheric Intraocular Lens

The increase of spherical aberration in eyes is one of the reasons for the visual quality descending with increase of age.Aspherics facilitated with wave-front technology is more close to the function of human crystalline lens and will become a new generation of the intraocular lenses,and they have the capable of correcting high order corneal aberration.Compared the spheric intraocular lenses,aspheric intraocular lenses can improve the image quality and therefore improve the patients′quality of life.
