New Surgical Treatment for Keratoconus

Keratoconus causes progressive corneal steepening and is devastating to vision via

For patients diagnosed with keratoconus, accepting how little can be done with modern medicine to protect and preserve their quickly declining vision can be the most devastating part of the diagnosis. Our current treatment model in the world of keratoconus goes something like this: try to keep going in contact lenses as long as possible, and when even those can't do the job anymore, time for a corneal transplant. Many patients live with a possible visual doomsday hanging over their head -- that day where contact lenses just won't work anymore and they might have to accept that they are going blind or needing major, risky surgery. Luckily, new technologies are being researched and explored that can stabilize the cornea and help prevent further vision loss.  Both corneal Intacs and corneal cross linking are currently performed in the United States, and both can help stabilize the degenerative process behind keratoconus. Unfortunately, not everyone is a candidate for these surgeries.  Advanced keratoconus patients whose corneal curvature is steeper than 60D or whose cornea is thinner than 350 microns wouldn't be able to pursue either of these surgical options due to the risk of complications.  But new research by Dr. Gerrit Melles in the Netherlands and Dr. Jack Parker with UAB has demonstrated a possible intervention that would stabilize the corneas of even these higher risk patients: Bowman's layer transplantation.
