Treatment of Keratoconus

Using glasses or soft contact lenses can be helpful in the early stages of Keratoconus, in which there aremyopia or regular astigmatism, but with disease progression and the incidence of irregular astigmatism, these two methods would no longer provide good vision for the patient.

The use of hard contact lenses (RGP) is necessary at this stage. By covering the irregular corneal surface with these smooth and regular lenses, refraction will be properly done.

Patients who cannot tolerate hard lenses can use hybrid contact lenses (a combination of hardware and software). An example of such lens, which is known as ClearKone brand, is readily available and can provide good vision for the patient; moreover, it is much more tolerable than the hard lenses.

The use of intra-corneal rings (INTACTS)and MyoRing, when patients cannot tolerate contact lenses, has created a great development in the treatment of this disease. Using this loops is not only better for with or without glasses vision of the patient, but also brings a better tolerance and prevents of the disease progression.

Cross Linking or corneal CXL is a method which, bya direct impact on the existing bonds between the collagen fibers of the cornea, causes an increase in strength of the cornea and prevents disease progression up to 5 years thereafter. In this method vitamin B2 (riboflavin) and ultraviolet radiation (UVA) are used for 5 to 30 minutes (depending on the radiation supplier machine) to stiffen the cornea.

Ultimately, in the case the previous approaches fail, or patient refer in advanced stages of disease, corneal transplantation or replacement of the cornea is a very successful and promising procedure. Depending on the severity of the disease, corneal transplantation can be performed as Lamellar or full thickness.

Tips necessary for patients with Keratoconus at the time of working with computers:

  • Using a large screen provides better working conditions for the patient.
  • Using a flat screen reduces Glare (Daze) at work. Also adjusting the ratio of the red, green and blue lights helps reduce the eye discomfort.
  • Using easier to read fonts like Arial or enlarging the fonts can be helpful.
  • Continuous working with the computer for long hours causes dry eyes and blurred vision. Taking a break (on a regular basis and at specified intervals) and engaging in something different, is very effective in reducing the symptoms of the patient's eye.
  • Installing the Enlargement Software would be helpful.
  • Using larger copies of the texts (e.g. A3) is recommended.


  • The amount of light available at living and work environment is very important for Keratoconuspatients and natural sunlight is the best. If the person is placed in an environment in which multiple light sources surrounds him, it is necessary for him to avoid looking directly at them. Using the study lights during the study helps some patients.
  • Work environments in which central heating system or air conditioners are used, cause dry eyes in patients with Keratoconus and may aggravate their irritation, especially in people who wear contact lenses. The use of an air humidifier (including water vapor devices) is very effective in reducing their discomfort.
  • Working in dusty environments or with too much dust can be problematic. In these circumstances, the use of IOL lenses that cover a large part of the whites of the eyes can be effective, otherwise using eye protectors that are designed for this purpose is essential.
  • These patients are advised to avoid driving at night if possible.
  • In case of attending classes, meetings or conferences, it is better to sit closer to the boards or screens.
