WebApr 10, 2024 · He explains that LIRIC spares the corneal nerves, causes much less damage to keratocytes and leaves the topography of the cornea intact, and notes, “Instead of ablation, LIRIC uses much lower pulse energies to modify the tissue’s refractive index. The change in refractive index is highly localized, like using a fine-point pen.” WebCorneal topography is a painless test that produces color-coded maps of your cornea. Your cornea is the clear, outer surface of your eye. It has a slightly curved shape that refracts (bends) light as it enters your eye, allowing you to see the world around you.
