INTRASTROMAL CORNEAL RING SEGMENTS (ICRS) OR INTRACORNEAL RINGS FOR KERATOCONUS:
In 1994, several American surgeons devised a technique called I.C.R.S. or Intra-Corneal Ring Segments. This operation consists in implanting stiff plastic rings in the corneal depth aiming to strengthen the cornea in its weakest points. These rings act as a mechanical reinforcement of the unhealthy part of the cornea.
At the moment two different types of I.C.R.S are used , INTACS and Ferrara rings. Each of which is suitable for treatment with corneas with specific anatomical characteristics (such as corneal thickness and maximum curvature). Preliminary results are satisfactory confirming the necessity of operating in the early stages of the illness in order to obtain good results.
Dr. Abbondanza has been studying keretoconus for over 30 years and, during his career, has become one of the leading experts on keratoconus and keratoconus conservative surgery, having been introduced in Italy the Corneal Collagen Cross-linking (2005) and having conceived himself a microsurgical technique to avoid corneal transplantation, the Mini Asymmetric Radial Keratotomy (MARK) in 1993.
