The Tecnis Eyhance IOL is an acrylic hydrophobic one-piece, foldable IOL with a total diameter of 13.0 mm and an optic diameter of 6.0 mm. It has a spherical posterior surface and a modified aspheric anterior surface which consists of a continuous increase in power from the periphery to the centre of the lens to maintain distance image quality comparable to aspheric monofocal IOLs [The Vivinex iSert IOL is an acrylic single-piece aspheric IOL with an optic size of 6.0 mm and an aspheric balance curve design, which was intended to reduce coma aberrations in addition to spherical aberration. Specifically, this IOL provides − 0.18 μm (6.0 mm pupil) of spherical aberration correction [
