Treatment device for the surgical correction of defective vision of an eye, method for producing control data therefore, and method for the surgical correction of defective vision of an eye
A treatment device for the surgical correction of defective vision in an eye. The device includes a laser apparatus controlled by a controller. The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea. The controller computes a lenticule-shaped intended volume, the removal of which from the cornea leads to an actual correction of defective vision in an optical zone in the eye which differs from the desired correction more at the edge of the optical zone than at the center of the optical zone. The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.
Methods and apparatuses for the treatment of glaucoma using visible and infrared ultrashort laser pulses
Transcorneal and fiberoptic laser delivery systems and methods for the treatment of eye diseases wherein energy is delivered by wavelengths transparent to the cornea to effect target tissues in the eye for the control of intraocular pressure in diseases such as glaucoma by delivery systems both external to and within ocular tissues. External delivery may be affected under gonioscopic control. Internal delivery may be controlled endoscopically or fiberoptically, both systems utilizing femtosecond laser energy to excise ocular tissue. The femtosecond light energy is delivered to the target tissues to be treated to effect precisely controlled photodisruption to enable portals for the outflow of aqueous fluid in the case of glaucoma in a manner which minimizes target tissue healing responses, inflammation and scarring.
Producing cut surfaces in a transparent material by means of optical radiation
A method for producing a cut surface in a transparent material using optical radiation. A laser device separates the material using optical radiation and includes an optical unit focusing the radiation along an optical axis into an image field defining an image-field size. A focal position is adjusted transversely along the axis, producing a cut surface extending substantially parallel to the axis and, in projection along the axis, is a curve having a maximum extent. The focus is displaced by adjustment of the focal position along a trajectory curve lying in the cut surface. The cut surface has a maximum extent which is greater than the image-field size. The focal position is moved transverse to the axis along the curve. The image field is displaced transversely, and the focal position is adjusted in an oscillating fashion along the axis on the curve between an upper and lower axial focus position.
Ophthalmological laser therapy device
An ophthalmological laser therapy device including a laser system, an x-y scanner, collecting optics and a z-scanner. The invention also relates to a method for processing a tissue of an eye by a therapeutic laser beam of an ophthalmological laser therapy device. The invention provides an ophthalmological laser therapy device and a corresponding method which permit, with minimal engineering complexity, a very quick positioning of the laser spot in a large volume region, in particular in a large x-y region perpendicular to the optical axis. The problem is also solved by a method for processing a tissue of the eye or a material located in an eye using an ophthalmological laser therapy device, wherein each sub-section of the tissue of the eye is processed using a corresponding positioning or the device for the adjustable redirecting of the laser beam in an image field of the collection optics.
