anterior chamber depth changes after phacoemulsification and intraocular lens implantation
purpose: to determine anterior chamber depth (ac depth) changes during a 6 month period after phacoemulsification cataract surgery and foldable intraocular lens (iol) implantation. methods: in a cross-sectional study, 85 eyes of 85 patients were evaluated for ac depth and capsulo-rrhexis size one and six months after the procedure. results: patients included 44 male and 41 female subjects with ...
متن کاملComparison of visual outcomes after bilateral implantation of a diffractive trifocal intraocular lens and blended implantation of an extended depth of focus intraocular lens with a diffractive bifocal intraocular lens
Purpose The purpose of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ® PanOptix® TNFT00 (group A), and blended implantation of an extended depth of focus lens, J&J Tecnis Symfony® ZXR00 with a diffractive bifocal intraocular lens, J&J Vision Tecnis® ZMB00 (group B). Methods...
متن کاملExtended depth of focus intraocular lens: Chromatic performance.
We describe a first-and-second-diffractive-order intraocular lens ((1st,2nd)DIOL) within the class of hybrid refractive-diffractive designs for intraocular lenses (IOLs) and analyse its properties of focus extension and compensation of longitudinal chromatic aberration (LCA), particularly for lenses with low addition. Power, energy efficiency and their wavelength dependence are extended from mo...
متن کاملTunable Focus Liquid Lens with Radial-Patterned Electrode
A dielectric liquid lens is prepared based on our previous work. By optimizing the device structure, the liquid lens presents a converging focus with good resolution and changes its focal length over a broad range with a low driving voltage. For a liquid lens with „2.3 mm diameter in the relaxed state, it can resolve „40 lp/mm. The resolution does not degrade during focus change. Its focal leng...
متن کاملLens-Based Depth Estimation for Multi-focus Plenoptic Cameras
Multi-focus portable plenoptic camera devices provide a reasonable tradeoff between spatial and angular resolution while enlarging the depth of field of a standard camera. Many applications using the data captured by these camera devices require or benefit from correspondences established between the single microlens images. In this work we propose a lens-based depth estimation scheme based on ...
