Abstract

Polymer-based nanocomposites exhibit various optical virtues such as a high refractive index (RI), the dispersion index (Abbe number (νd)) and visible light transmittance (T %) about 95-99%. Titanium dioxide nanoparticles (TiO2 NPs) is suggested as a good candidate to rise the RI and maintain high transparency when it is integrated with Poly(methyl methacrylate) polymer PMMA because TiO2 NPs have a high RI (2.45 and 2.7 for anatase and rutile phase, respectively). The ocular performance was evaluated by modulation transfer function (MTF) and image simulation. The used criteria show that the best visual performance is obtained when TiO2-PMMA-CL of 0.1 wt/volume of TiO2 NPs is used (P < 0.0001) which reduced the generated spherical and chromatic aberrations inside the eye
