ABSTRACT:
A corneal topography system incorporating a handheld unit, a base unit and a computer. The handheld unit includes a placido projector, a light source and a camera that receives the image of the placido image being reflected off of the patient's cornea. The light source is preferably comprised of a lightweight luminescent panel such as an EL panel. The handheld unit further includes a laser and a display that are used to properly align the handheld unit with respect to the patient's cornea into a desired orientation. The resulting reflected image is captured when the handheld unit is in the desired orientation and this image can then be used to obtain corneal topography data for the patient's eye.
