Background: To evaluate cumulative dissipated energy (CDE), laser time, central corneal thickness and endothelial cell loss after two different fragmentation pattern by means of femtosecond laser-assisted cataract surgery (FLACS). Methods: Eighty eyes of 80 patients that underwent FLACS were randomized in two groups: mixed chop and dice lens fragmentation pattern (group 1 with 40 eyes) and mixed chop and cylindrical lens fragmentation pattern (group 2 with 40 eyes). Results: Cumulative dissipated energy was significantly lower in group 1 compared to group 2 (p<0.001). Postoperatively there was a decrement of endothelial cells count at the centre of the cornea in both groups compared with preoperative values with greater decrease in Group 2 (p<0.001). The thickness at the tunnel site showed a greater increase in group 2 compared to group 1 immediately after surgery (p<0.001) The thickness measured at the center of the cornea increased slightly immediately after surgery and showed a similar decrease in both groups. The increase was greater in Group 2 (p<0.001). Conclusions: Both lens fragmentation patterns were effective in nucleus disassembly. Nevertheless dice pattern was related with a lower amount of CDE and induced lower central endothelial cell loss and lower increase of corneal thickness. Show less

The visual presentation of the results of the analysis of cardio graphic information is an important element of the diagnostic process. The article discusses the issues of visualization of the state of the heart, notes the importance of a visual representation of the processes of the functioning of the heart for diagnosis. The Delaunay triangulation is considered and it is proved that on its basis it is possible to approximate an arbitrarily complex surface. An algorithm for constructing a surface model of the heart based on Delaunay triangulation has been developed. The issues of texture generation are covered in detail. The texture is a convenient tool for displaying the state ofthe heart, as it allows you to visually show the place of possible damage on the surface of the heart. Show less
