Method for reducing longitudinal spherical aberration of intraocular lenses

It has been established that of all types aberrations following the implantation intraocular lenses, most significant is spherical, inherent in spherical optics various aspects. This paper proposes a method for reducing longitudinal aberration lenses by applying an additional optical layer onto their surface. To reduce aberration, thickness polytetrafluoroethylene (Teflon) was simulated programming environment Zemax 13 (USA). Calculations were performed included refractive indices and material optics. order to value lens made hydrophobic acrylic, aTeflon should be about 100 nm. The results spraying indicate improvement characteristics aberration. When examining different areas with spraying, it there no area. In 4 mm zone, indicator decreased times compared original lens. region diameter 6 mm, 0.2. Applying Teflon reduced Fresnel reflection times, which improves sensitivity contrast vision. properties provide anti-adhesive state lens, counteraction development secondary cataracts.
