Integrated Scanning and Ocular Tomography System and Method
First Claim
1. A method of treating a tissue, the method comprising:
- directing an ablative beam for ablating the tissue via a scanning device to the tissue;
directing a measurement beam for measuring a profile of the tissue via the scanning device to the tissue, wherein a path of the ablative beam and a path of the measurement beam are substantially concentric as directed onto the tissue.

Abstract
Systems and methods of the present invention measure at least one reflecting surface of an object disposed along an optical path. In some embodiments a measured optical interference signal for each of at least three wavelengths of reflected light may be used to determine a modulation of frequency components of a Fourier series. Frequency components of a Fourier series may be transformed to spatial components that describe intensities and positions of light reflected along an optical path. Systems and methods of the present invention permit rapid measuring and may monitor corneal thickness during surgery. The invention may do so by integrating an ablation device and a measurement apparatus into a single system. An integrated scanning and monitoring system may include an ablative light source producing an ablative beam and a measurement light source producing a measurement beam.

5. An apparatus for ablating tissue, the apparatus comprising:
-
an ablative light source producing an ablative light beam;
a measurement light source producing a measurement light beam; and
a scanner receiving the ablative beam from the ablative light source and the measurement beam from the measurement light source, the scanner including optical elements for directing the ablative beam and the measurement beam to locations across the tissue so as to ablate the tissue with the ablative beam and measure a profile of the tissue with the measurement beam, a path of the ablative beam and a path of the measurement beam being substantially concentric at the tissue. - View Dependent Claims (6, 7)
