WebIn this paper, using the Richards–Wolf formula we simulate the focusing of a cylindrical vector beam (CVB) of second order. It is shown that toroidal vortices periodically appear at a distance of about 0.45 μm from the axis (with a period along the z-axis of 0.8 μm) when the light is focused by a lens with numerical aperture NA = 0.95 ... WebIn only one eye, the difference in IOL orientation observed before and at the end of the enhancement surgery was greater than ±10° (10.7°). Regarding the rotational stability after ENH, the IOL orientation rotated an average of −0.04±3.51° (−8.7°–6.1°). Again no trends in the direction of IOL rotation were observed. flocking powder silicone
