ICRS is an ophthalmic medical device designed for the reduction or elimination of myopia and astigmatism in patients with keratoconus so that their functional vision may be restored and the need for a corneal transplant procedure can potentially be deferred.
ICRS implantation, on average, improves two-line visual acuity in 50% of patients with keratoconus, although some patients may have a more pronounced improvement. In fact, patients who before surgery did not have good vision with glasses due to the loss of corneal irregularity, typically enjoy better vision with new glasses after ring implantation.
Advantages of ICRS
- Causes no histological changes in the central cornea and maintain the natural state of cornea
- Potential reversibility to the situation before the surgery – they can be removed if needed.
