The Ferrara intrastromal corneal ring segments (ICRS) are designed to treat ectatic corneal disorders, especially keratoconus. They have been used to reshape keratoconic corneas to improve uncorrected visual acuity, best-corrected visual acuity, contact lens tolerance and to delay or prevent the need for keratoplasty. Intrastromal corneal ring segments have several distinct and important advantages. The Ferrara ICRS have been used largely in several countries for the treatment of primary and secondary ectatic corneal disorders. This article reviews the latest data published and the clinical experience/findings on the treatment of keratoconus by the Ferrara ICRS implantation.
