Corneal Diseases include corneal abrasions, corneal deformities, irregular astigmatisms (following corneal implants) and postoperative cataract extraction with acquired astigmatism.
Corneal topography equipment is used to create a map of the surface of the cornea. This equipment consists of a computer linked to a lighted bowl that contains a pattern of rings. During a diagnostic test, you will sit in front of the bowl with your head pressed against a bar while a series of data points are generated. Computer software digitizes these data points to produce a printout of the corneal shape, using different colors to identify different elevations, much like a topographic map of the earth displays changes in the land surface. The non-contact testing is painless and brief.
