Premium IOLs are revolutionizing cataract surgery by giving patients new options for excellent vision without glasses. The next generation of IOLs is bringing us closer to the goals of perfect refractive results and excellent accommodative amplitudes patients. The diffractive ridges of the former, however, extend all the way to the edge of the optic, which should give patients better reading ability in low-light settings such as a dimly lit restaurant.
Chromatic aberration reduces image quality in normal white light "Accommodating iol synchrony care" each of its color wavelengths refracts differently. The Tecnis Multifocal IOL is made of an acrylic material with chromatic aberration, which is better than that of the crystalline lens. This helps optimize the focus of normal white light for distance and near vision.
The approval of toric multifocal lenses, such as the Acri. The Synchrony has an anterior optic with a high plus power and a posterior optic with a high negative power Figure 1.
The dual-optic design yields a power that is equivalent to that of a standard IOL.
While the ciliary body is relaxed, the two optics are relatively close together for distance vision. As the ciliary body contracts and the zonule relaxes, the optics move apart, Accommodating iol synchrony care increasing the power of the lens and resulting in near acuity. Distance and near vision was equivalent with the two lenses, but the Synchrony provided significantly better binocular intermediate vision at 60 cm.
A subjective perception of glare and halos at night was more common in the AcrySof Restor group.
