The local structure of correlated spin-orbit insulator Sr$_{2-x}$M$_x$IrO$_4$(M = K, La) has been investigated by Ir L$_3$-edge extended x-ray absorptionfine structure measurements. The measurements were performed as a function oftemperature for different dopings induced by substitution of Sr with La or K.It is found that Ir-O bonds have strong covalency and they hardly show anychange across the N\'eel temperature. In the studied doping range, neither Ir-Obonds nor their dynamics, measured by their mean square relative displacements,show any appreciable change upon carrier doping, indicating possibility of ananoscale phase separation in the doped system. On the other hand, there is alarge increase of the static disorder in Ir-Sr correlation, larger for K dopingthan La doping. Similarities and differences with respect to the local latticedisplacements in cuprates are briefly discussed.
