  • Patent number: 7232587
    Abstract: The invention includes a method for the passivation of the surface of an intraocular lens, wherein the surface includes Brönsted sites. The intraocular lens is dipped into a solution of a fluoroalkyl silane having the general formula: Rf—(CH2)n—Si—(O—R)3. The residue R is selected from the group of H, CH3, C2H5 and C3H7 and the fluoroalkyl residue Rf is selected from the series CF3(CF2)m, with m=3 to 11 and n=0 to 4. The Brönsted sites on the surface are thereby deactivated by formation of Si—Q—bonds.

  • Patent number: 7101564
    Abstract: The invention relates to a plastically deformable implant for inserting into bodily orifices of the human or animal body. Implants of this type are used, for example, in ophthalmology, in particular, as vitreous body or lens replacements and in dentistry, for example, for filling extraction cavities in jaw-bones. Known implants, however, are not suitable for long-term use. The invention aims to provide a deformable plastic implant which also has a long-term application. This is achieved by the fact that the implant consists of a gel which is not sealed, containing fluorocarbon and which is directly introduced into the natural, or artificially created bodily orifice.

  • Patent number: 7001607
    Abstract: A tear replacement solution that contains at least one water-soluble fluorosurfactant, water and a non-polar component, preferably in gel form, and a method for the external treatment for the eye of an mammal by applying the tear replacement solution to the eye, preferably by placing in the conjunctival sac.

  • Publication number: 20040166236
    Abstract: The invention relates to a method for the passivation of the surface of an intraocular lens, the surface of which comprises reactive Brönsted sites. Conventional methods of the above type create changes on the original material and exhibit undesired interactions with medical adjuncts. The aim of the invention is to describe a method in which the intraocular lens is passivated and coated in an advantageous manner and only minimal changes are brought about on the original material. Said aim is achieved, whereby the intraocular lens is dipped in a solution of a fluoroalkylsilane of general formula RF—(CH2)n—Si—(O—R)3, where R═H, CH3, C2H5, or C3H7 and the fluoroalkyl group RF═CF3 (CF2)m where m=3 to 11 and n=0 to 4, whereby the Brönsted centres on the surface are deactivated by formation of Si—O bonds.

  • Patent number: 6372243
    Abstract: The present invention concerns fluorocarbons for use in ophthalmology. Fluorocarbons disclosed in the prior art can only be left in the eye for a limited period of time because they cause damage to the retina or intraocular structure. The present invention provides an oxygen-fluorocarbon mixture having a dissolved oxygen content of less than 6% by volume, which can be used as an ophthalmological agent for longer periods of time than conventional fluorocarbons, with little or no damage to the retina or intraocular structures. The invention also provides a process for preparing the oxygen-fluorocarbon mixture. In one embodiment, up to 20% by volume of a second gas, such as carbon dioxide or nitric oxide, is combined with the oxygen-fluorocarbon mixtures.
