  • Patent number: 12004811
    Abstract: In a corneal measurement system, an optical element focuses an excitation light to an area of corneal tissue at a selected depth. In response, a fluorescing agent applied to the cornea generates a fluorescence emission. An aperture of a pinhole structure selectively transmits the fluorescence emission from the area of corneal tissue at the selected depth. A detector captures the selected fluorescence emission transmitted by the aperture and communicates information relating to a measurement of the selected fluorescence emission captured by the detector. A controller receives the information from the detector and determines a measurement of the fluorescing agent in the area of corneal tissue at the selected depth. The system may include a scan mechanism that causes the optical element to scan the cornea at a plurality of depths, and the controller may determine a measurement of the fluorescing agent in the cornea as a function of depth.

  • Patent number: 12005002
    Abstract: A corneal lenticule extraction procedure provides convenient re-treatment options when treatment interruptions occur. The procedure is executed by an ophthalmic laser system according to a programmed treatment plan, which defines an entry cut, an optional ring cut, a bottom lenticule incision having an optical zone, and a flat top bed incision. If an interruption occurs during the entry cut, the treatment plan is re-aligned with the partially formed entry cut and continued, or with a new entry cut placed at a different angular position. If an interruption occurs during the ring cut, the treatment plan is revised to define a larger ring cut concentric with the partially formed ring cut. If an interruption occurs during the bottom or top incision, the depth of the partially formed bottom or top incision is measured, and the treatment plan is revised to form a deeper bottom incision or a shallower top incision, respectively.

  • Patent number: 12002567
    Abstract: A look-up table for use in determining an energy parameter for photodisrupting ocular tissue with a laser is generated by determining a plurality of individual spot size distributions, wherein each of the plurality of individual spot size distributions is based on a different set of simulated data and includes an expected spot size of a laser focus at each of a plurality of locations within a modeled target volume of ocular tissue. The plurality of individual spot size distributions are combined to obtain a final spot size distribution that includes a final expected spot size of the laser focus at the plurality of locations of the focus within the modeled target volume of ocular tissue. An energy value is assigned to the plurality of locations of the focus within the modeled target volume of ocular tissue based on the final expected spot size at that location.

  • Patent number: 11911104
    Abstract: A laser eye surgery system focuses light along a beam path to a focal point having a location within a lens of the eye. The refractive index of the lens is determined in response to the location. The lens comprises a surface adjacent a second material having a second refractive index. The beam path extends a distance from the surface to the focal point. The index is determined in response to the distances from the surface to the targeted focal point and from the surface to the actual focal point, which corresponds to a location of a peak intensity of an optical interference signal of the focused light within the lens. The determined refractive index is mapped to a region in the lens, and may be used to generate a gradient index profile of the lens to more accurately place laser beam pulses for incisions.

  • Patent number: 11896528
    Abstract: An ophthalmic laser treatment delivers patterned laser energy to an eye of a patient. A pattern-scanning laser device of the laser treatment system includes a laser module, a scanning module and delivery optics. The laser module generates laser energy (e.g. via a green laser diode), which is directed to the scanning module via a fiber optic cable. The scanning module produces the patterned laser energy by reflecting the laser energy into the delivery optics at different angles via a dielectric MEMS scanning mirror. The delivery optics includes an F-theta lens, a motorized and wirelessly-controlled spot-size selector module, and a focusing lens. A mobile computing device receives parameter information via a graphical user interface or voice control and sends the parameter information to the pattern-scanning laser device. In response to receiving activation signals from an activation unit, the pattern-scanning laser device emits the patterned laser energy based on the parameter information.
