The introduction of any new method of corneal diagnostic measurement presents an opportunity for the evaluation of its routine clinical application in larger clinical numbers. As ophthalmologists become more comfortable with new techniques, refinements often make the technology more accessible to other clinicians. Corneal topography continues to evolve, as new techniques and features are introduced that make clinical imaging of the corneal shape and curvature more accurate. This technology is critical for many diagnoses such as keratoconus, planning surgical correction on the cornea, IOL calculations, and monitoring corneal treatments already performed. A new unit that uses color-coding shows promise.
