What is AcrySof IQ IOL?

Its shares the essential design top features of the Acrysof Natural IOL with the modifications of its optic design to get a posterior prolate surface reducing its central thickness. Unlike the cornea, it introduces negative spherical aberration (0.2 µm) that lowers the spherical aberration of the attention. It has been reported to provide better contrast sensitivity, quality of vision and fewer aberration with the aspheric IOL when compared to conventional IOL. However, some studies have discovered that conventional IOLs have better depth of focus than aspheric IOLs allowing the patient to accomplish better intermediate and near vision. Conversely, Mester et al found no difference in depth of focus between both IOLs. The non-diffractive AcrySof® IQ VivityTM Extended Vision Posterior Chamber Intraocular Lens Model DFT015 (known as AcrySof® IQ VivityTM IOL) is a UV-absorbing and blue light filtering foldable intraocular lens .

An aberration can be an irregularity in the form of the eye’s refractive surface that can distort vision. One kind of higher order aberration common to cataract patients is spherical aberration, which can result in a gradual reduction in vision acuity and function. As you get older, your eye’s lens gets thicker and rounder, causing image quality to deteriorate. Conventional IOLs implanted after phacoemulsification result in a spherical aberration of approximately 0.08 µm adding to the already positive corneal aberration of the attention. In order for the patient to reach the perfect functional vision, efforts have led to the development of the aspheric IOLs.

Because this lens does not offer the ability to accommodate or adjust one’s focus at varying distances, glasses would be required for near and intermediate tasks. The AcrySof IQ intraocular lens implant is also an excellent choice for individuals who enjoy driving during the night, since it delivers great clarity with reduced reports of glare or haloes under reduced lighting conditions. In past times, all cataract patients had to wear reading glasses and/or bifocals after cataract surgery because only monofocal IOLs were available.
