Abstract
In order to take advantage of the real time nature of intra-operative refraction or wavefront aberrometry, and visually make the history of the measurements apparent to a surgeon, a histogram of frequency vs IOL results calculated from an IOL formula is computed and IOL suggestions being accumulated are displayed in a histogram. One embodiment is a means to present to a surgeon a histogram of intra-operative refractions. Another embodiment is to automatically and intra-operatively detect the aphakic phase of a cataract surgery to display a histogram of a recommended IOL power.
