Abstract
In one embodiment, a wavefront sensor is combined with a slit lamp eye examination device so that real time aberration values of an eye being examined can be viewed during a slit lamp eye examination session.
Claims9
An apparatus comprising:
- a real-time wavefront sensor configured to continually sample a first set of wavefronts returned from an eye of a patient over a time interval during which an accommodation of the eye of the patient is being changed, and with the real-time wavefront sensor configured to output wavefront measurement data characterizing the first set of wavefronts;
- an internal fixation module configured to project an image onto the eye of the patient to change the accommodation of the eye of the patient;
- and
- a controller, coupled to the wavefront sensor and the internal fixation module, with the controller configured to monitor the output wavefront measurement data and compare the first set of wavefronts to reference wavefronts while controlling the internal fixation module to change the accommodation of the eye of the patient during the time interval and with the controller further configured to indicate when the change of accommodation causes the first set of wavefronts to substantially differ from the reference wavefronts to indicate accommodation limit(s) of the eye of the patient.
1 more element
An apparatus for measuring refractive error of a patient eye during an operative procedure on the patient eye, the apparatus comprising:
- a real-time wavefront sensor configured to continually sample a first set of wavefronts returned from a patient eye over an intra-operative time interval during which a procedure for titrating the refraction of the patient eye is performed, and with the real-time wavefront sensor configured to output wavefront measurement data characterizing the first set of wavefronts;
- and
- a data processor, coupled to the real-time wavefront sensor to receive the wavefront measurement data, with the data processor configured to analyze wavefront measurement data characterizing the first set of wavefronts to detect a value of a residual astigmatism of the patient eye and configured to output an indication of the residual astigmatism during the intra-operative time interval.
