Twenty-four eyes of 24 senile cataract patients who underwent phacoemulsification and Acc-IOL implantation were enrolled.
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.1 A major difficulty with diffractive optics is chromatic aberration, which is generally worse than with refractive optics.At 3 months postoperatively, the best corrected distance visual acuities (BCDVA), distance-corrected near visual acuities (DCNVA), and subjective and objective accommodations were measured.IOL shifts under accommodation stimulus ( was 130.46 ± 42.71 µm.The latter has been the subject of considerable debate. In 1855, Hermann von Helmholtz suggested that a constriction of the ciliary body musculature leads to slackening of its attached lens zonular fibers, producing a consequential increase in lens curvature.
Chromatic aberration reduces image quality in normal white light because each of its color wavelengths refracts differently.
