The measurement provides valuable information to our doctors for prescribing contact lenses and Corneal Refractive Therapy, reducing the amount of time required to get you the best prescription. This technology also allows our doctors to properly identify candidates for laser vision correction and monitor the healing response after corneal surgery. Corneal topography also is invaluable in assisting our doctors in detecting sight-threatening corneal pathology including keratoconus and pellucid marginal degeneration.
