Isaac Porter, MD explains the tests and evaluation needed to determine if a patient is a candidate for LASIK or PRK. In a free evaluation, the stability of the eyeglass or contact lens prescription is checked to ensure that it is not currently changing. Specialized mapping of the cornea shows detail of the curvature of the eye and can help identify problems like keratoconus that do not qualify for LASIK. Wavefront testing passes light in and out of the eye to measure every distortion in the vision. The thickness of the cornea is measured and an eye exam is performed to check the overall health of the eye. Using this information, it can be determined if a patient qualifies for laser vision correction.
