The distance between two distinct fundus landmarks, i.e. two crossings of retinal vessels, was measured before and after surgery, and the results were compared to axial length and surgery\u2010induced change in ametropia and anterior chamber depth. In addition, the change in the conversion factor of Topcon fundus camera was calculated and its correlation to axial length, change in ametropia and anterior chamber depth was analysed. Further, the change in the mathematical location of P\u2032, i.e. the second principal point of the eye in the formula of Bennett et\u00a0al.
