Obtaining and Displaying Histogram and/or Confidence of Intra-Operative Refraction and/or IOL Power Recommendation

A method for real time detection and measurement of aberration values of a wavefront returned from a subject eye, wherein the method is adapted to be performed while a surgical procedure on a subject eye is ongoing, with the method performed by a computer system coupled to receive wavefront aberration values from a wavefront sensor configured to measure real time aberration values of a wavefront returned from the eye of a subject while an image of the subject eye is being viewed by an operator during an ongoing vision correction procedure, coupled to receive pre- or intra-operative biometric measurements of the subject eye being viewed by an operator during the ongoing vision correction procedure from a biometric parameter measurement module, and coupled to a display, the method comprising:

• disqualifying unreliable measured real time aberration measurements received from the wavefront sensor based on qualifying parameters including one or more of eye alignment measurements, wavefront power measurements, high-order aberration measurements, prismatic wavefront tilt, and inter-frame wavefront steadiness to collect a set of qualified real time aberration values;
• calculating and storing qualified intra-operative refraction values of the subject eye based on qualified wavefront measurements;
• recording the occurrence frequency of stored qualified refraction values of the subject eye;
• intra-operatively detecting whether the patient eye is in the phakic, aphakic, or pseudo-phakic phase of the vision correction procedure in real time based on the difference between pre-operative predicted values of refraction power and measured intra-operative phakic, aphakic, or pseudo-phakic values of refraction power of the subject eye;
• displaying a real time image of the subject eye, a histogram of occurrence frequency distribution of the qualified refraction values, and/or a histogram of occurrence frequency distribution of IOL powers predicted based on an IOL predictive algorithm that incorporates among other parameters the aphakic refraction of the subject eye in one or more of the phakic, aphakic, or pseudo-phakic phase of the vision correction procedure, an indication of the phase of the vision correction procedure, a pre-operatively determined target refraction value, and one or more of most recent qualified intra-operative refraction values.
