Intacs for Keratoconus

Intacs can greatly improve eyesight. They also can improve a person's tolerance for contact lenses.

The clear front surface of the eye, called the cornea, helps focus light on the retina, to produce clear vision. Blurry vision results if the cornea does not keep its normal shape. For instance, conditions such as keratoconus make the cornea bulge forward. This leads to distorted vision.

People with early keratoconus may have good eyesight with glasses. But, as their eye disease worsens, they most often need a rigid contact lens to improve vision quality. In time, the cornea may become so misshapen or scarred that a contact lens fails to give the desired visual correction.


Until recently, the only treatment option at this stage was a corneal transplant. This surgery safely improves vision in most people with advanced keratoconus. However, it is a complex surgery that requires visual rehabilitation afterward.

Option to Transplant

A new alternative to corneal transplant is a corneal implant called Intacs. These micro-thin, curved implants are made of the same material as rigid contacts. With a laser, the surgeon creates small channels in the cornea. Then the surgeon implants the Intacs inside the channels and positions them to reshape the cornea for better vision. These microscopically small implants are barely visible.
