Corneal topography
Informed by recognized medical guidance
Overview
Corneal topography is a non-invasive eye test that creates a detailed map of the cornea — the clear, dome-shaped front surface of your eye. This map shows the shape, curvature, and thickness of your cornea, helping eye doctors detect and monitor conditions that affect its surface.
Key facts
- It uses a special camera or scanning device, no contact with the eye.
- The test is painless and usually takes just a few minutes.
- It helps diagnose problems like keratoconus (a thinning and bulging of the cornea) and guides treatments like contact lens fitting or surgery.
Corneal topography is a common diagnostic test in ophthalmology clinics, especially for people with unexplained vision problems or those considering laser eye surgery.
It is used for anyone with suspected corneal irregularity — from children with poor vision to older adults with astigmatism or after eye surgery.
