  • Publication number: 20110001926
    Abstract: A device for a therapeutic treatment of the eye by means of a laser is provided, which allows a real-time monitoring of the treatment. In particular, the laser light is supplied to the treatment region via a fibre. The monitoring of the treatment happens by means of optical coherence tomography (OCT). To this end the OCT measurement beam and the treatment laser light are coupled in a probe that is put onto the eye and allows to focus the OCT measurement beam on the tissue region inside of the eye that is treated at that moment.

  • 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: 7026359
    Abstract: The invention relates to the utilization of a highly fluorinated oligomeric alkane as a therapeutic agent in ophthalmology, the alkane having the general formula [—RF(CH2)nCR1—CR2—]x, wherein RF is a linear or branched perfluorinated alkyl chain C2F5 to C12F23, R1 and R2 are independently selected from the group consisting of H, CH3, C2H5 and C3H7, n is selected from the numbers 0, 1 and 2, and x is a number between 2 and 6, with a molar mass of at least 750. According to the invention, a pharmacological agent is provided that is used in ophthalmology and that causes little or no damage to the retina even when used over a long period.

  • 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.
