The use of adaptive optics systems in ophthalmic research studies has increased in the last years thanks to the development of more accurate devices. Adaptive optics was first introduced in Astronomy for the correction of the effects produced by the turbulences of the Earth’s atmosphere when observing astronomical objects (1,2). Sophisticated deformable mirrors controlled by computers can correct in real time atmospheric disturbances, allowing for much finer details on the images of distance objects. Adaptive optics technology makes it possible to correct many of the aberrations with which the wavefront, i.e., the geometric envelope of all the rays of light that emerged at the same time of the observed object, arrives. Adaptive optics allows for obtaining sharper images, and thus, with better spatial resolution.
