A device for isolating a lenticle in the cornea of an eye. The device includes: a laser beam source to emit pulsed laser radiation having a pulse frequency of 1.2 MHz to 10 MHz, a pulse energy of 1 nJ to 200 nJ and a wavelength penetrating the cornea; a beam-forming unit having ...
Cause: The excessive curvature of the cornea or an elongated eyeball increases the overall refractive power of the eye, causing light to converge too quickly. Correction: Myopia is typically corrected with concave lenses (negative lenses) in glasses or contact lenses. These lenses diverge light rays...
it is still relatively limited. In other words, “it’s not like being able to look at the entire cornea,” Dr. Schuman said. “On the other hand, what you’re able to see is quite impressive.”
The human eye, for example, needs only a cornea and a single lens to form an image. But on average, one human retina contains twenty-five million rods and six million cones. Today's high end cameras use lenses with from six to twenty elements. Only the rarest, most expensive cameras ...
in the cornea (12) and inside the image field, wherein the focus (13) moves along a track when the image field is idle, a control unit (14), which is designed to actuate the laser beam source (5) and the beam forming unit (9), in order to isolate the lenticule in the cornea ...
and which has a maximum diameter of less than 3 m; a beam-deflection unit shifting the focus in the cornea and inside the image field, the focus moving along a path when the image field is resting; and a control unit to control the source and the beam-forming unit to isolate the lent...

In order to expose the inner surface of the cornea, removing part of the flap-like living cornea, the blank (18) is arranged inside on the exposed surface of the eye. Portion of the inner surface in response (ie, myopia, or hyperopia,) on the type of refractive error eye conditions ...
