Abstract:

Keratoconus is a corneal ectatic disease that is characterized by noninflammatory progressive thinning. Since the utilization of penetrating keratoplasty and rigid contact lenses, there was no improvement for the visual rehabilitation of the keratoconus. Recently, intracorneal ring segments have been investigated to correct ectatic corneal diseases. The aim of implanting intracorneal ring segments is not to treat or eliminate the existing disease, rather a surgical alternative to decrease the astigmatism and corneal abnormality and thus increase the visual acuity to acceptable limits, aiming to at least delay, if not eliminate, the need of corneal grafting. Since its release, intracorneal ring segment implantation for keratoconus seems to be an effective and, most of all, reversible treatment with minimal complications. Conversely, long-term results should be analyzed regarding stability, predictability and the need for further corneal transplantation in the long term.
