Abstract:

Cornea curvature and aberrations will change after corneal refractive surgery. Hyperopic error still exists and the increase of higher-order aberrations also affects the visual quality after cataract surgery in such patients. Therefore, the new IOL power calculation methods have emerged to reduce refractive predictive error. Aspheric IOL selection according to cornea spherical aberration before cataract surgery can reduce the whole eye aberrations and patient’s visual symptoms such as glare, decreased night vision and improve the visual quality.
