Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea.
The cornea (the front window of the eye) is responsible for about 70 percent of the eye’s focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results.
The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing.
Corneal topography produces a detailed, visual description of the shape and power of the cornea. This type of analysis provides your optometrist with very fine details regarding the condition of the corneal surface.
These details are used to diagnose, monitor, and treat various eye conditions.
Corneal topography can be utilised in the fitting of contact lenses and the associated costs are charged as part of this process. Using Corneal Topography to detect irregular Corneal conditions often requires additional appointments that will be charged accordingly.
