Abstract:
1. A method of registering datasets of an eye obtained by two different instruments, the method comprising: obtaining a first high-order optical tissue surface shape dataset from an eye with a first instrument while the eye is aligned with the first instrument; obtaining a first image of the eye associated with the first dataset while the eye is aligned with the first instrument and while obtaining the first dataset; obtaining a second high-order optical tissue surface shape dataset from the eye with a second instrument while the eye is aligned with the second instrument while the eye is not aligned with the first instrument, the second instrument being separate from the first instrument; obtaining a second image of the eye associated with the second dataset while the eye is aligned with the second instrument and while obtaining the second dataset; locating a plurality of distinctive data points of the eye in each of the datasets, the distinctive data points for each dataset identified from the associated image by comparing calculating values from across the image; and using the distinctive data points to torsionally register the first dataset with the second dataset.
