Corneal Topography measures the shape of the eye’s surface. It will take a couple of minutes.
How does it work?
You look into the instrument and fixate on a light. You will see a bright flash.
Dr. Bender will get a topographic map from your eye, like mountain range topography showing peaks and valleys. How flat or steep is your eye?
This is important for monitoring certain anterior eye diseases such as keratoconus, but also to determine the exact curvature on contact lenses needed.
Dr. Bender uses this exam to get information about aberrations caused by the shape of the eye. The values will be compared from exam to exam.
