Not meeting appropriate endothelial cell density as determined by an age-dependent minimum (range 1900- 3875 cells/mm2), see Table 1 ; Table 1. WebThe recommended lens powers range from -10.00 to 10.00 D in the majority of these cases. The correct axial length measurement is very difficult to obtain because of the abnormal anatomy of the posterior pole. ... For patients with axial lengths shorter than 21 mm, I recommend performing IOL power calculations with the Holladay 2 formula. In ...

Webit operates well over a fixed range of axial lengths, but it performs less well outside that range. Alternatively, the Haigis formula seeks additional precision by using 3 lens constants (a0, a1, and a2), which adjust both the shape and position of the IOL power prediction curve. The a0 constant moves the power predic- WebThe Artis Symbiose Mid IOL is superior for intermediate distances, and the Artis Symbiose Plus is superior for near distances.
