Intracorneal rings



INTACS® intra-corneal implants contribute to the reduction or elimination of myopia and astigmatism in patients with keratoconus.


INTACS® intra-corneal implants are designed to modify the anterior corneal curvature to correct myopia without interfering at the central visual axis. Different thicknesses and arc lengths can be implemented according to the position of the cone and the myopia dioptres and astigmatism in need of correction.
