If your eye doctor sees a disease or condition in your eye, they will perform this test again with other, higher-resolution imaging techniques. The image is also saved to be compared with examinations that you have later on. Once the image is taken, it is examined by an ophthalmologist for various eye diseases.

Corneal topography helps surgeons select the right IOL in some cases.
RETINA SCAN COST HOW TO
A topography scan helps the surgeon understand how to precisely reshape the cornea.
Refractive surgery. During refractive surgery like LASIK, the shape of the cornea is changed to correct refractive errors like myopia (nearsightedness).How Does Corneal Topography Help with Surgery? If the scan shows a lot of distortion, sometimes a special hard contact lens (RGP) can help correct vision. Contact lens fitting. Topography scans help find what type of contact lens can be worn to improve vision.Astigmatism and keratoconus. Topography can help find astigmatism and early cases of keratoconus and track their progression.Growths. The size of pterygia or other growths can be monitored with topography.A topography scan measures the distortion and its effect on vision. Scarring. Trauma (injury) or infections can scar the cornea.What Conditions Is Corneal Topography Used for? It also helps doctors monitor eye disease and plan for surgery. But with a topography scan, a doctor can find distortions in the curvature of the cornea, which is normally smooth. It works much like a 3D (three-dimensional) map of the world, that helps identify features like mountains and valleys. Corneal topography is a special photography technique that maps the surface of the clear, front window of the eye (the cornea).
