Embodiment Construction

[0031]FIG. 1 shows a first exemplary embodiment of the present invention for treating an opacity in the vitreous body in the visual field directly behind the lens. Focusing optics 12 are connected downstream of a laser 10, here a mode-locked laser. A deflection mirror with micromanipulator 14 is arranged downstream of the focusing optics. A contact glass 15 is placed on the eye 1 to be treated. A clouded region 5 is situated downstream of the eye lens. A surgical microscope with slitlamp 19 is used for monitoring.

[0032]The mode-locked laser system is used to generate ultrashort laser pulses, preferably of 10 ps to 10 fs, which are further amplified using the Chirped Pulse Amplification Method to make available pulse energies above 1 ml in the kHz range. At the wavelength of 780 nm (Ti-sapphire) or 1060 nm (Nd:glass), the transparent regions of the cornea, lens or vitreous body to be treated have a low absorption which are not damaged when irradiated with sufficiently low energy dens...

Abstract

The present invention relates to a method and a device for treating opacities and / or hardenings of an unopened eye.It is a specific advantage of the solution according to the invention that the treamtment of the inner region of the eye is possible without the need to introduce a surgical instrument into the eye.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a method and a device for treating opacities and / or hardenings of an unopened eye. Specifically, the present invention relates to a laser system and a method for cleaning, in particular, the ageing human eye from gray hazes in the cornea, the lens or the vitreous body to restore transparency in the eye.[0002]In ophthalmology, it is known that, in particular in the ageing eye, opacities develop in the lens (cataract) or in the vitreous body or the cornea. At the advanced stage, the treatment is presently limited to replacing the lens with a plastic lens during a cataract surgery, replacing the vitreous body with silicone oil by vitrectomy, or also to transplanting the cornea. It is known to carry out the surgery of the cataract and the vitrectomy of the vitreous body using a laser. During a surgery, the laser beam is in both cases led directly to the tissue to be treated. A proven efficient laser is, in particular, the...
