Keratoconus is a disease that creates a thinning of the cornea or the clear front surface of the eye. Normal outward pressure within the eye causes the cornea to progressively bulge into a cone-like shape. The change in the cornea’s shape can have a dramatic impact on one’s vision. In more severe cases, normal everyday activities such as driving and reading can be difficult to perform.
Initially, a person with early stage keratoconus will notice a subtle change in their vision. As the disease progresses, one’s vision will fluctuate and frequent changes to one’s glasses or contact lenses often occur. This happens as a result of a thinning taking place within the cornea and bulging caused by one’s normal eye pressure pushing on the weakened front surface of the eye. As the disease continues to advance, the light rays entering the eye become significantly distorted, which is called irregular astigmatism. The outer portion of the eye begins to bulge, creating what often looks like a cone shape.
 
 
Intacs® Corneal Implants and Intacs® SK Corneal Implants are an ophthalmic medical device designed for the reduction or elimination of myopia and astigmatism in patients with keratoconus so that their functional vision may be restored and the need for a corneal transplant procedure can potentially be deferred. When placed in the corneal stroma, outside of the patient’s central optical zone, the product reduces the cone by flattening the cornea.
 
Intacs® segments are designed to be placed in the periphery of the cornea, at approximately two-thirds depth, and are surgically inserted through a small radial incision in the corneal stroma. The Intacs® are designed to allow removal or replacement. Intacs® and Intacs® SK Corneal Implants are manufactured from polymethylmethacrylate (PMMA) and are available in different thicknesses, ranging from 0.210 mm to 0,500 mm. The product is designed with a fixed outer diameter and width. Intacs® and Intacs® SK Corneal Implants have positioning holes located at each end of the segment to aid in surgical manipulation.
 
The Intacs® SK segments are designed with rounded edges to potentially reduce the incidence of visual symptoms since de SK segments are placed closer to the patient’s central optical zone than the standard Intacs segments.
