Latest Patents

One of Vaughn's latest patents focuses on the rapid, automatic measurement of the eye's wave aberration. This innovative method determines the wavefront aberration of an eye in real time. The process involves illuminating the eye and converting the light reflected from the retina into spots using a device such as a Hartmann-Shack detector. The displacement of each spot from its expected position allows for the calculation of the aberration. An iterative technique is employed to locate each spot's centroid, refining the measurement through smaller boxes drawn around the centroid. The wavefront aberration is then calculated using a matrix that can eliminate unusable data by removing rows. This method also accommodates different pupil sizes through data taken for a single pupil size by renormalization.
