Technology has offered a number of new devices that allow improved care for patients in many areas of healthcare. For vision care, corneal topography gives eye care professionals greater detail about the curvatures and features of the eye surface. This information is important in prescribing the appropriate vision correction for each patient’s needs. Lehigh Valley Eyecare Associates use corneal topography to provide optimized vision care for their patients.
Topography is the process of viewing the visual surface of an object and providing a graphic or numerical representation of what is seen. The cornea is the dome-shaped covering on the eye surface that refracts light on the retina at the back of the eye, to produce clear images of what is seen. Mapping the cornea of the eyes helps eye doctors to understand the precise shape of the eye surface. A number of different devices are used for this purpose. Generally, they all use the reflection of light off the corneal surface to provide information about characteristics of the eye’s surface. Computer-assisted videokeratography (CAVK) is used to produce a 3-dimensional map of the corneal surface, which is used to determine the health of the eyes. During your eye exam, your Allentown eye doctor will use corneal topography to precisely fit contact lenses and to determine changes in the eyes that could indicate an eye problem.
Corneal topography aids in determining the amount of vision correction needed to compensate for irregularities in the shape of the cornea that causes refractive errors, such as near-sightedness, farsightedness and astigmatism. The process is also used for determining whether a patient is a suitable candidate for LASIK eye surgery. Corneal topography can also be used to detect certain eye diseases, such as keratoconus and astigmatism that may occur after cataract surgery.
