In this article, we give an analytic construction of ALF hyperkähler metrics on smooth deformations of the Kleinian singularity $mathbb{C}^{2}/{mathcal{D}}_{k}$ , with ${mathcal{D}}_{k}$ the binary dihedral group of order $4k$ , $kgeqslant 2$ . More precisely, we start from the ALE hyperkähler metrics constructed on these spaces by Kronheimer, and use analytic methods, e.g. resolution of a Monge–Ampère equation, to produce ALF hyperkähler metrics with the same associated Kähler classes.
