Corneal topography is the process of 3D mapping the surface of the cornea and shape of the eye. A healthy eye with normal vision has an evenly rounded outer shape, while a flat or uneven shape can indicate an imperfection or disorder. This is an important tool, as identifying an atypical cornea shape can provide your doctor with information regarding the condition of your eye. Some of the conditions that can be identified by corneal topography include:
- Fuchs’ endothelial dystrophy
- Bullous keratopathy
- Corneal abrasions or deformities
- Irregular astigmatism
Corneal topography can also be used for other needs like assistance in planning for cataract surgery, fitting of contacts, or LASIK.
During the exam, the patient is seated in front of a bowl-shaped device that contains a series of illuminated rings. The light is projected onto the outer surface of the eye and the shape of the cornea is reflected back into the digital camera. The computer which is linked to the camera is then able to assess many angles of the corneal surface and get a detailed view of its’ overall condition. The process is completely painless as no physical contact is directly made by any equipment.
