The aim of intracorneal rings is to modify the refractive power of the cornea. This surgical technique is performed under local anesthesia and consists of introducing, in the corneal thickness, an acrylic plastic implant with the form of a ring to reinforce the structure of the cornea and modify its curvature, respecting the central area.
It is indicated, mainly, in cases of deformity of the cornea associated with poor vision and intolerance to correction with contact lenses and glasses, such as keratoconus, ectasia and irregular astigmatism.
