Embodiments of the present invention relate to systems and methods for removing the fixation light reflection from an ophthalmic image. In one embodiment, an ophthalmic laser treatment system, having a digital imaging system for capturing images of a patient's eye and a visual fixation light source configured to produce a fixation light upon which the patient's eye can be focused, further includes a filter configured to remove from the image any light reflection caused by the visual fixation light source.

대표청구항 ▼

1. An ophthalmic treatment system comprising: one or more visual fixation systems configured to produce one or more fixation lights upon which a patient's eye can be focused;a digital microscope positioned to capture an image of the patient's eye, wherein the digital microscope capture images in sequential frames with an inter-frame time period between the frames during which the digital microscope does not capture image data;a display device operably coupled to the digital microscope to display the image of the patient's eye captured by the digital microscope; anda switch operably coupled to the digital microscope and the one or more visual fixation systems and configured to cause any of the one or more visual fixation systems to produce the visual fixation lights only during the inter-frame periods of the digital microscope, wherein no fixation light enters the patient's eye during time periods when the digital microscope captures the images in the sequential frames. 2. The system of claim 1, wherein the ophthalmic treatment system comprises a laser ophthalmic surgical system having a laser delivery system for delivering a pulsed laser beam to a patient's eye. 3. The system of claim 2, wherein the laser delivery system includes an excimer laser. 4. The system of claim 2, wherein the laser delivery system includes a non-ultraviolet, ultra-short pulsed laser. 5. A method for providing an ophthalmic-based treatment comprising: a. capturing an image of a patient's eye with a digital microscope, wherein the digital microscope capture images in sequential frames with an inter-frame time period between the frames during which the digital microscope does not capture image data;b. displaying the image on a display device; andc. producing visual fixation lights only during the inter-frame periods of the digital microscope, the visual fixation lights being produced in front of the eye to focus the eye at a desired position, wherein no fixation light enters the patient's eye during time periods when the digital microscope captures the images in the sequential frames. 6. The method of claim 5, wherein the ophthalmic-based treatment is laser-based treatment having a laser delivery system for delivering a pulsed laser beam to an eye. 7. The method of claim 6, wherein the laser delivery system includes an excimer laser system. 8. The method of claim 6, wherein the laser delivery system includes a non-ultraviolet ultra-short pulsed laser system. 9. The method of claim 5, wherein the producing step includes using a controller to synchronize power delivered to the visual fixation light to an inter-frame signal so that the visual fixation light turns on only during the inter-frame time periods. 10. The method of claim 9, further including a switch or connector coupled to the visual fixation light which receives the inter-frame signal from the controller and turns on the visual fixation light only during the inter-frame time periods.
