Corneal Topography

Corneal topography is a diagnostic technique used in ophthalmology to map the curvature of the cornea's surface. This procedure creates a detailed, three-dimensional image of the cornea, essential for assessing conditions like astigmatism, keratoconus, and evaluating the outcomes of refractive surgeries such as LASIK. The topography is achieved using either Placido disc-based systems or more advanced Scheimpflug imaging. Placido disc-based systems analyze the reflection pattern on the cornea's surface, while Scheimpflug imaging captures multiple cross-sectional images, allowing for a more precise measurement of anterior and posterior corneal surfaces. By analyzing corneal topography, ophthalmologists can customize contact lenses, plan surgeries, and monitor the progression of certain eye conditions. This non-invasive procedure plays a crucial role in optimizing visual outcomes and maintaining eye health for patients with corneal abnormalities.
