Abstract: An optical system and method for photographing an eye fundus in which a fundus camera having a focus control is aligned with the position of an eyelens. An automatic optometer is coupled to the fundus camera and is adapted to sense refractive power of the eye. Means are coupled to the automatic optometer and the fundus camera for controlling the focus of the fundus camera and activating the fundus camera to take a photograph when the focus of the fundus camera matches the instantaneous refractive power of the eye.
