We discuss possible ways to enlarge the size of high-resolution area (isoplanatic patch) in fundus imagers equipped with adaptive optics. We first developed customized human eye models of several subjects. Then we considered immersion and multiconjugate methods of isoplanatic patch widening. Using immersion method we obtained about twotimes enlargement of isoplanatic patch size for the developed eye models. For optimal configuration of a multiconjugate system with two correctors and five reference sources isoplanatic patch area increased two times if compared with the case of conventional correction. We consider immersion method to be more preferable due to its relative simplicity and low-cost.
