1 results about "Corneal ablation" patented technology

A laser system for detecting a corneal ablation threshold potential by means of spectral analysis, comprising a sample module (4), a femtosecond laser transmitter module (1), and a laser focusing module (2), characterized in that the laser system further comprises a spectral analysis module (3), wherein the sample module (4) serves to receive a corneal sample, the femtosecond laser transmitter module (1) serves to transmit a laser beam, the laser focusing module (2) serves to focus the laser beam onto the sample module (4), and the spectral analysis module (3) serves to perform spectral analysis of a laser-induced plasma light signal and to detect a corneal ablation threshold potential, and wherein the femtosecond laser transmitter module (1) transmits a laser beam which, after focusing by the laser focusing module (2), appears on the corneal sample of the sample module (4), wherein the corneal sample, after laser induction, laser-induced plasma light signal emitted,which is sent via the laser focusing module (2) to the spectral analysis module (3) so that the spectral analysis module (3) performs a spectral analysis of the laser-induced plasma light signal and a detection of the corneal ablation threshold potential, wherein the spectral analysis module (3) is configured to determine, by analyzing the spectral information of the laser focusing points, whether the laser is focused on the cornea or other substances, taking into account that the spectrum produced by corneal tissue is different from the spectrum produced by other substances in contact with the cornea.
