WebApr 11, 2024 · Due to the large number of microspheres analyzed, the histogram now reveals the bimodal distribution of the two populations more clearly. Normal kernel smoothing uncovers two maxima at refractive indices of 1.3366 and 1.3405, respectively, with a count ratio of 0.88, very similar to the ratio found in the stationary case, 0.82 (Figure 4c). WebA different approach to IOL calculations is the use of ray tracing calculations. These are exact calculations based on Snell´s Law, using available data to calculate the best focus for single rays at varying radial distances from the optical axis through the different refractive media of the eye. bus to oban from edinburgh
