Abstract:
1. A fundus camera, comprising: three fluidic lenses, each of the three fluidic lenses having a chamber that receives a fluid therein, an amount of the fluid being inserted into the chamber or removed from the chamber by a fluid control system, such that the shape of each of the three fluidic lenses is changed based on the amount of fluid therein, one of the three fluidic lenses comprising a spherical lens with a circular transparent membrane and at least another of the plurality of fluidic lenses comprising a cylindrical lens with a rectangular transparent membrane, the spherical lens being disposed in front of the cylindrical lens relative to a path of light being reflected back from the eye such that the reflected light enters the spherical lens prior to entering the cylindrical lens; a light source configured to direct light into an eye; a refractive or diffractic telescopic system configured to transmit the light, which is reflected back from the eye and through the three fluidic lenses, to a Shack-Hartmann sensor; the Shack-Hartmann sensor by means of the fluid control system automatically controlling the amount of the fluid in the chamber of each of the three fluidic lenses, so as to be capable of correcting refractive errors in the eye; and a multifunction camera configured to acquire precise fundus images of the eye.
