Corneal topography produces a detailed, visual description of the shape and power of the cornea.
Corneal topography is a special photography technique that maps the surface of your cornea. Your cornea is the clear, front window of the eye. With a topography scan, a doctor can find distortions in the curvature of the cornea.
This analysis provides your doctor with information to help diagnose, monitor, and treat various eye conditions.
This also helps your doctor determine what contacts lenses are the most suitable for you, whether you need scleral lenses or have high astigmatism, and what kinds of lenses you will likely find the most comfortable.
