The present invention provides methods and test devices for aligning a diagnostic device with a laser refractive system. In one embodiment, the device comprises a body comprising a proximal portion and a distal portion. The proximal portion defines a radiused corneal surface and an iris, and the distal portion defines a retinal surface. The test devices of the present invention typically have visual and optical characteristics that are similar to a human eye.
