Optimizing vision correction procedures
View Patent ↗In one embodiment a wavefront sensor is configured to measure real time aberration values of a wavefront returned from the eye of a patient while an image of the eye of the patient is being viewed by a surgeon during an on-going vision correction procedure and for providing an output signal indicating real time aberration values and a display, coupled to the wavefront sensor, is configured to show a dynamic display indicating the real time aberration values to the surgeon and configured to be viewed by the surgeon while also viewing the image of the eye of the patient during the on-going vision correction procedure.
1. An apparatus comprising:
a wavefront sensor configured to measure real time aberration values of a wavefront returned from the eye of a patient while an image of the eye of the patient is being viewed by a surgeon during an on-going vision correction procedure and for providing an output signal indicating real time aberration values; and
a display, coupled to the wavefront sensor, configured to show a dynamic display indicating the real time aberration values, output by the wavefront sensor, to the surgeon and with the display configured to be viewed by the surgeon while also viewing an image of the eye of the patient during the on-going vision correction procedure.
2. The apparatus of claim 1 with the wavefront sensor further comprising:
an offsetting mechanism; and
a controller, coupled to the offsetting mechanism, configured to receive user input from the surgeon during the vision correction procedure and to control the offsetting mechanism, in response to the user input, to offset selected wavefront aberration components in order to highlight or amplify clinically important features of other non-offset aberration components of the wavefront returned from the eye of the patient.
3. The apparatus of claim 1 further comprising:
a detection mechanism that outputs aberration values resulting from the tilt of different sub-portions of the wavefront where the dynamic display is formed by displaying the aberration values.
4. The apparatus of claim 3 where the detection mechanism comprises:
a single position sensing device that measures the tilt of different sub-portions of the wavefront that are sequentially directed onto the single position sensing device.
5. The apparatus of claim 4 further comprising:
a beam scanning mechanism for directing different sub-portions of the wavefront onto the single position sensing device.
6. The apparatus of claim 5 where the beam scanning mechanism directs sub-portions included in an annular ring portion of the wavefront onto the single position sensing device.
