The advantage of Aspherical Hydrophilic Acrylic Foldable IOLs with Zero Spherical Aberration

The spherical aberration of the natural lens of the human eye is very complicated and changes with age, adjustment and other factors. The investigation found that the average spherical aberration of the human cornea is 0.27μm, 90% of which present positive spherical aberration, and 10% present negative spherical aberration. Therefore, the negative spherical aberration design is not suitable for all people, and the zero spherical aberration design is suitable for a wider range of people. 

After implantation of the Aspherical Hydrophilic Acrylic Foldable IOLs with Zero Spherical Aberration , a little positive spherical aberration of the whole eye is retained, providing patients with a false adjustment of about 0.5D, obtaining more depth of field, and making the visual effect more perfect.
