Corneal topographer is a computerised eye care diagnostic tool that creates a three dimensional map of the surface curvature of the cornea. The cornea is responsible for about 70 percent of the focusing power of the eye. An eye with normal vision has an evenly rounded cornea. If the cornea is irregular due to high astigmatism or visual distortion, corneal topographer will be the best eye care tool to detect especially cornea eye disease like keratoconus.
Optometrists are using sophisticated techniques like corneal topographer, to get better cornea alignment with the back of surface of rigid gas permeable contact lenses. The new technology allows optometrist to get good results of well-centred rigid gas permeable contact lenses on the eye, providing good health, comfort and vision.
