This maps the corneal surface, detects irregularities in your corneal shape, and permits precise contact lens selection. This instrument is the most accurate instrument available at measuring astigmatism - an abnormality in the corneal surface that makes contact lens fitting more challenging. Our topographer allows our doctors a more accurate assessment of your prescription and enables us to prescribe contact lenses for those difficult to fit.
Our office has the most advanced corneal topography system available. This device projects a series of light rings onto the cornea of the eye and then captures the reflections on a video camera. The result is a detailed three dimensional topographical map of the cornea. This information is vital to the preoperative and posoperative refractive surgery candidate, to the design of complex soft and rigid gas permeable contact lenses and is used in the diagnosis of corneal disease and curuature abnormalities.
