COMBINED OPHTHALMIC LASER DEVICE

摘要

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.

主权项

1. An ophthalmic laser combined device comprising one laser source emitting short pulses with high peak power at the first wavelength of 1064 nm, said source being attenuated by an attenuator and collected to a patient's eye by way of collimation optic; that in the same optical axis of the laser beam having the basic wavelength of 1064 nm an optical system with another wavelength of 532 nm is provided, said optical system comprising attenuators, a module from crystals for frequency doubling, which changes the first wavelength to the second one, and collimation optic that collects the laser pulse of the second wavelength in the patient's eye.
