摘要:
Systems and methods for removing an epithelial layer disposed over a stromallayer in a cornea irradiate a region of the epithelial layer with a pulsed beamof ablative radiation. The ablative radiation is scanned to vary the locationof the beam within the region in accordance with a pulse sequence. The pulse sequenceis arranged to enhance optical feedback based on a tissue fluorescence of theepithelial layer. The penetration of the epithelial layer is detected in responseto the optical feedback. The use of scanning with the pulse sequence arrangedto enhance optical feedback allows large areas of the epithelium to be ablatedsuch that an operator can detect penetration of the epithelial layer.
