Abstract
Purpose:: Conventional optical systems usually provide best image quality on axis with unavoidable gradual decrease in image quality towards the periphery of the field. Image quality can be considered invariant within a limiting field region known as the isoplanatic patch. Measuring the isoplanatic patch of the eye is complicated by the fact that the eye is a non-centered and non-rotationally symmetric system without a uniquely defined optical axis. It is known that the field-dependent component of lower-order aberrations (defocus and astigmatism) account for the largest contribution to the total wavefront error for each field point. However, the basis and choice of an optimal ocular axis that maximizes the size of the isoplanatic patch after correction with an Adaptive Optics (AO) system has not been established yet.
