Digital Corneal Topography
3D Mapping of the curvature of the cornea
The cornea, which is the clear front surface of the eye, plays an important role in focusing your vision. An eye with normal vision has a rounded cornea however a cornea that is too steep or too flat causes reduced vision.
Digital corneal topography is a three dimensional imaging process used to map the surface curvature of the cornea and is invaluable in the investigation of eye complications, fitting of contact lenses and when evaluating pre- and post-surgical patients.
The precise data gathered from topography can be used in the diagnosis and management of keratoconus and give insight into scarring and irregular astigmatism.
The measurements are so accurate that the Optometrist is able to tailor-make contact lenses from the data but it is also invaluable in determining the best lens type and fit in contact lens consultations as the Optometrist is able to see the irregularities in the shape of the cornea in far more detail than using a slit lamp.
