Bowman layer transplantation effective in advanced keratoconus
Isolated Bowman layer transplantation can reduce and stabilize corneal ectasia in eyes with progressive advanced keratoconus, researchers said. “It flattens the cornea into a more normal position,” said Jack Parker, MD, a researcher at the Netherlands Institute for Innovative Ocular Surgery (NIIOS) in Rotterdam, The Netherlands. “It doesn’t give them perfect vision, but it keeps them from getting worse. It lets them to continue wearing their contact lenses.”

In a recently published study (van Dijk et al. Ophthalmology. 2015 May. 122:5;909-917) , the procedure produced an average flattening of about 8 D in 20 eyes, and a stabilization after that. There were two complications.
In keratoconus, the cornea gradually bulges outward in the shape of a cone, distorting the patient's vision.

Glasses and contact lenses can correct mild cases, and hard contact lenses as well as implantation of intracorneal ring segments can help in moderate cases. However, in severe cases the distortion of the cornea may progress to the point that the contact lenses become too uncomfortable to wear.
