M.A.R.K. (Mini Assymetric Radial Keratotomy)

MARKOn the basis of the previous experiences, Dr. Abbondanza devised a new surgical technique called Mini Asymmetric Radial Keratotomy (M.A.R.K.).
M.A.R.K. flattens the cornea and reduces visual aberrations, that appear as a result of corneal deformation, but since it is performed only in the area where the keratoconus is localized, both the flattening and the structural reinforcement of scar tissue occur only locally in the distorted zone, while excessive flattening of the cornea is avoided.. The primary result of MARK is a significant improvement of vision. The second important result is the stopping or slowing of disease progression.
The first operations were performed in 1994 and routine check-ups have shown stabilization of the operated corneas.
Today many surgeons worldwide have adopted the surgical technique recognizing the results and improvements of visual performance.
Dr. Abbondanza has been researching and treating keratoconus for over 20 years and especially considers M.A.R.K. surgery, alone or combined with other treatments such as corneal crosslinking, as highly effective for obtaining the best possible optical correction and corneal stabilization.
