The present model of corneal ring relies on a new concept of a limbus and corneal mid-periphery remodeling in which due to the curvature determined by the spacial disposition of two concentric rings (one with 5 mm and the outer ring with 8 mm diameter), the prolapsed corneal curvature can be managed by the 40D curvature determined by this singular corneal ring model (keraring nk model).
