Biointerface multiparametric study of intraocular lens acrylic materials.
PURPOSE To compare hydrophilic and hydrophobic acrylic materials designed for intraocular lenses in a multiparametric investigation in a liquid environment to highlight their properties in terms of adhesion forces, lens epithelial cell (LEC) adhesion, and tissue response as indicators of the risk for posterior capsule opacification (PCO) development. SETTING University of Liège, Liège, Belgiu...
متن کاملTreatment of ophidism-induced bilateral canine cataract by extracapsular lens extraction and intraocular lens implantation
The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...
متن کاملIntraocular lens design and the inhibition of epithelium.
Of 1170 eyes implanted with posterior chamber lenses between 1981 and 1986 and having intact capsules at surgery, 1015 were examined two years after surgery, 741 were examined three years after surgery, and 308 were examined five years after surgery. At three years the capsulotomy rate for epithelium was 25% for 263 'lasergap' lenses, 2.4% for 296 convex posterior lenses, 8.2% for 73 planoposte...
متن کاملLens epithelial cell regression on the posterior capsule with different intraocular lens materials.
BACKGROUND/AIMS Posterior capsular opacification (PCO) is caused by proliferation and migration of lens epithelial cells (LECs) across the posterior capsule and is the commonest cause of reduced vision after cataract surgery. The influence of intraocular lens (IOL) material on the process of LEC migration was studied. METHODS 90 eyes underwent standardised extracapsular surgery, with capsulor...
متن کاملTriplet design as an intraocular lens for high myopia.
We present the possibility of using a triplet as an intraocular lens (IOL). The matrix method was used to calculate the power of this triplet for high myopia. The thickness of the lens, the distances between the edges of the IOL and the endothelium, the distances between the edges of the IOL and the iris, and the nfluence of axial displacement have been analyzed. We have also compared the size,...
