CORNEAL RINGS INSERTION OF INTRASTROMAL CORNEAL RING SEGMENTS
CORNEAL RINGS
Corneal rings, also called corneal ring segments, are small plastic devices implanted at the corneal stroma to smooth the shape of the front portion of the eye and to reduce the refractive error, which is due to keratoconus, and other ectatic disorders of the cornea.
Also, they have been designed for the treatment of keratectasia, providing a better result in smoothing the corneal surface.
