Intracorneal rings

The irregular shape of the cornea in keratoconus causes a distortion to vision especially at night.     

The Intracorneal Rings surgical procedure is designed to improve vision in patients with keratoconus when glasses and contacts lenses are no longer tolerated. Intracorneal rings can also postpone the need for corneal transplant. Once the rings are implanted, they are virtually invisible to the naked eye.     


The Intracorneal Ring procedure involves placing thin, clear, semi circular, plastic rings into the cornea. 

The rings are carefully placed inside an opening less than 2mm wide inside the cornea. Vision is improved as the shape of the cornea becomes more regular. The degree of shape change is controlled by the thickness of the rings. Intracorneal rings can be removed if needed.
