Slide 1. Aberrometry (left) showing superior coma with topography (right) of the same eye. The topography does not demonstrate any vertical asymmetry, suggesting that the coma originates in the lens. Corneal-based procedures in this eye such as wavefront-guided LASIK would induce new corneal aberrations and may not provide a satisfactory outcome.

Slide 2. An eye with coma originating in the cornea. The aberrometry (left) and topography (right) images show symmetric patterns, indicating the aberrations are present on the cornea. |
