Intrastromal Corneal Rings

How does it work?

INTACS® Inserts are implanted through a small surgical incision on the perimeter of the cornea. The inserts help restore clear vision in keratoconus patients by flattening and repositioning the cornea.

When is it used?

INTACS® Inserts are intended for patients with keratoconus who are no longer able to achieve adequate vision using contact lenses or glasses and for whom corneal transplant is the only remaining option.

What will it accomplish?

The inserts may restore functional vision and postpone the need for a corneal transplant.

When should it not be used?

INTACS® Inserts should not be used in keratoconus patients who:

• Can achieve functional vision on a daily basis using contact lenses
• Are younger than 21 years of age
• Do no have clear central corneas
• Have a corneal thickness less than 450 microns at the proposed incision site
