Despite acceptable visual acuity on paper, spectacles were not prescribed, as visual quality was expected to remain poor.
๐น Corneal Topography:
On the sagittal map, PMD demonstrates the classic
โButterflyโ or โKissing Birdsโ pattern,
with a relatively flat central cornea โ a key feature distinguishing it from keratoconus.

โ๐ป Why Scleral Contact Lenses?
Because they vault over the irregular cornea, neutralize irregular astigmatism, and create a smooth optical surfaceโimproving visual quality, comfort, and night vision, not just visual acuity๐๐ผ.
