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.
