Abstract: An electronic device includes one or more processors; and memory storing one or more programs. The one or more programs include instructions for: initiating a first light source to emit first light; while the first light source emits the first light, receiving, at a first image sensor, a first image of light from the eye, transferred through the lens assembly and an array of lenses; initiating a second light source to emit second light; and, while the second light source emits the second light, receiving, at a second image sensor, a second image of light from the eye, transferred through the lens assembly. The first light emitted from the first light source is transferred toward an eye through a lens assembly. The second light emitted from the second light source is transferred toward the eye.

Abstract: Devices and methods for wavefront sensing and keratometry are described. A device includes a lens assembly, a wavefront sensor, and a keratometer. The wavefront sensor includes: the lens assembly; a first light source configured to emit first light and transfer the first light emitted from the first light source toward an eye through the lens assembly; an array of lenses that is distinct from the lens assembly; and a first image sensor configured to receive light, from the eye, transmitted through the lens assembly and the array of lenses. The keratomer includes: the lens assembly; a second light source that is distinct from the first light source and configured to emit second light and transfer the second light emitted from the second light source toward the eye; and a second image sensor configured to receive light, from the eye, transmitted through the lens assembly.
