Intacs®

Intacs® are a treatment option for Keratoconus patients for whom corneal transplant is the only remaining treatment option.

Intacs® are clear, thin inserts called intrastromal corneal ring segments (ICRS) that are a treatment option for Keratoconus patients who can no longer achieve satisfactory vision correction with contact lenses and for whom corneal transplant is the only remaining treatment option.

Intacs® are placed in the outer edge of the cornea and reshape the curvature of the cornea without removing any corneal tissue. They are designed to normalize the shape of the cornea to allow for better contact lens fit and can be removed or replaced if needed.

Intacs® are inserted approximately two-thirds depth, outside the central optical zone, into a small channel that is created in the middle of the cornea either manually or with laser assistance. The laser-assisted method is extremely precise, and the safety and benefits of the laser are why nJoy vision offers only the laser-assisted method.

According to FDA guidelines, Intacs® corneal implants for the treatment of Keratoconus are intended for the reduction or elimination of myopia and astigmatism in patients with Keratoconus who are no longer able to achieve adequate vision with their contact lenses or spectacles so that their functional vision may be restored and the need for a corneal transplant procedure can potentially be deferred. The specific subset of Keratoconus patients proposed to be treated with Intacs® corneal implants have:

  • Experienced a progressive deterioration in their vision, such that they can no longer achieve adequate functional vision with their contact lenses or spectacles
  • Clear central corneas
  • A corneal thickness of 450 microns or greater at the proposed incision site
  • Corneal transplantation as the only remaining option to improve their functional vision
