Patent number: 10299960Abstract: Systems and methods to treat a region of a cornea of an eye having an epithelial layer disposed over a stromal layer. The system comprises a device to map a thickness of the epithelial layer over the region of the cornea to generate a map of epithelial thickness over the region, and a laser to generate a laser beam of an ablative radiation. A movable scan component is coupled to the laser to scan the laser beam over the region. A processor system is coupled to the laser and the movable scan component, and the processor system is configured to arrange pulses of laser beam to ablate the epithelial layer of the region in response to the map of epithelial thickness.Type: GrantFiled: June 28, 2016Date of Patent: May 28, 2019Assignee: AMO DEVELOPMENT, LLCInventors: Keith Holliday, Mark E.

Publication number: 20180064579Abstract: Systems and methods for removing an epithelial layer disposed over a stromal layer in a cornea irradiate a region of the epithelial layer with a pulsed beam of ablative radiation. The ablative radiation is scanned to vary the location of the beam within the region in accordance with a pulse sequence. The pulse sequence is arranged to enhance optical feedback based on a tissue fluorescence of the epithelial layer. The penetration of the epithelial layer is detected in response to the optical feedback. The use of scanning with the pulse sequence arranged to enhance optical feedback allows large areas of the epithelium to be ablated such penetration of the epithelial layer can be detected.Type: ApplicationFiled: November 6, 2017Publication date: March 8, 2018Inventors: Mark E. Arnoldussen, Jonathan Wong, Benjamin A. Logan, Leander Zickler
