  • Patent number: 9883971
    Abstract: The object of the invention is a laser device for eye surgery used by ophthalmologists in the treatment with capsulotomy and iriditomy, and a device for selective laser trabeculoplasty. The essence of the ophthalmic laser combined device of the invention lies in that it has one single laser with one optical axis for both wavelengths; the basic wavelength of 1064 nm and the frequency doubled wavelength of 532 nm. Switching between both wavelengths is carried out by a polarization orientation switch. Frequency doubling is inactive at the wavelength of 1064 nm and it is active for the wavelength of 532 nm. At the wavelength of 532 nm additional optical elements for attenuating and collimating the laser pulse are switched on.

  • Publication number: 20050270487
    Abstract: The light source 1 in the slit lamp (FIG. 1) according to present invention is a white light emitting diode (LED) controlled by a control circuit 8. The patient's eye is illuminated by an illuminating slit produced as image 7 of the slit 3 by means of Koehler illumination technique. This means that the phosphorescent surface of the LED is projected through the condenser optics 2 onto the rear objective 4 that makes an image of the slit 3 through a prism or a mirror 6 onto the eye. In this way an evenly illuminated image 7 of the slit 3 is formed on the inspected eye. The control circuit 8 ensures a correct ratio between the voltage across the LED and the current flowing through the LED and enables changing of the emitted light intensity. The color of the light does not vary with the intensity of the light. In an embodiment of the invention, the light source of the slit lamp is a LED emitting simultaneously a red, a green, and a blue light.
