Corneal Topographer

A corneal topographer is a digital imaging technique for mapping the surface curvature of the cornea (the very front, clear part of the eye). The allows our Optometrist to evaluate the shape of the cornea before any contact lens fitting, and also to detect any corneal abnormality such as irregular corneal shape or eye diseases such as keratoconus.

At iSight, we routinely take images of the cornea before any contact lens fitting. This allows us to help you find the contact lens that best suits your eyes. (A common misconception is that contact lenses are a one-size-fit-all.) Not only will a properly fitted contact lens give you better comfort and vision, it will also protect the health of your cornea from poorly fitted lenses.

Corneal topography is also a MUST when fitting children with myopia control lenses, such as Orthokeratology fitting. This will ensure that each lens is custom made according to the natural curvature of the eye, and to monitor changes in the cornea during the treatment. Improperly fitted lenses without corneal topographer will lead to serious consequences.
