Keratoconus changes vision in two ways:

  • As the cornea changes from a ball shape to a cone shape, the smooth surface also becomes slightly wavy. This is called irregular astigmatism.
  • As the front of the cornea expands, the eye becomes more nearsighted. That is, only nearby objects can be seen clearly. Anything too far away will look like a blur.

New eyeglasses can usually make vision clear again in mild cases of keratoconus. Eventually, though, it will probably be necessary to use contact lenses. Rigid lenses are used most frequently in keratoconus patients.

Keratoconus is a noninflammatory, progressive disease. It characterized by a progressive thinning and ectasia of the stroma that results in a cone-shaped cornea. In advanced keratoconus with corneal opacities, keratoplasty was regarded as the only surgical option. However, new alternatives have been developed in the treatment of keratoconus.

Keratoconus is a disease of the corneal stroma that usually presents itself in patients at an early age. As a result, the endothelial cell layer in eyes with keratoconus is young and healthy. Full-thickness penetrating keratoplasty has been a well-accepted surgical treatment for advanced keratoconus. Recently, medical advances have been seen and new techniques of keratoplasty have been introduced in the treatment of keratoconus. These are mainly the lamellar keratoplasty techniques and the advanced shaped side-cut techniques, particularly with the use of femtosecond lasers.
