Keratoconus- Ayurvedic Treatment, Diet, Exercises, Research Papers, Yoga & Pranayama


The cornea is the transparent front part of the eye through which we see. In normal condition, the cornea is a round surface which holds the curvature for proper focusing which is essential for vision. But in some case, the cornea becomes weak in structure and the pressure inside the eye makes the cornea bulge outward like a cone. This condition is called keratoconus.

Signs & symptoms

  • A sudden change of vision in just one eye.
  • Double vision when looking with just one eye.
  • Distorted vision in the beginning, not blurred. After a long time, distant objects do become blurred.
  • Halos around bright lights.
  • Astigmatism
  • Blurred Vision
  • Difficulty Seeing in Dim Light
  • Distorted Vision
  • Double vision
  • Glare
  • Near-sightedness
  • Ring of Discoloration on the Front of the Eye
  • Sensitivity to light


The exact cause of keratoconus is unknown.

Some studies have found that keratoconus runs in families.


Keratoconus usually begins in childhood or teenage, before the age of 30. The changes in the shape of the cornea occur slowly, usually over several years.

Keratoconus changes to vision in two ways:

  • As the shape of the cornea changes from a ball to a cone, the smooth surface becomes slightly wavy. This condition is known as irregular astigmatism.
  • As the front of the cornea expands, the eye becomes more near-sighted. That is, only nearby objects can be seen clearly. Far away objects will look like a blur.


Measurement of curvature of the cornea using instruments like keratometer, which shines a pattern of light into the cornea. The shape of the reflection of the pattern tells the doctor how the eye is curved.Corneal topography makes three-dimensional “maps” of the cornea.


  • New eyeglasses, and then contact lenses to correct vision changes

New eyeglasses will be able to make the vision clear in mild cases of keratoconus. In the long run, it will be needed to use contact lenses. Rigid lenses are used most frequently in keratoconus patients.

  • Corneal transplantation will be needed in severe cases.


The condition will progress at a moderate pace for ten to twenty years and stops in a person late 30’s or 40’s. Most of the patients find relief by the usage of glasses/contact lenses. About 10% will need a corneal transplant for a complete cure.


Distorted vision, although not complete blindness

The inability of the eye to focus without eyeglasses or contact lenses.

Keratoconus can be dangerous if laser vision correction surgery — LASIK or PRK is performed on the eye.

Anyone with even a mild tendency of keratoconus should not have laser vision correction surgery.

  • Control any allergic reactions
  • Wear UV-blocking sunglasses while going out
  • Keep the eyes and eye wares hygienic
  • Avoid scratching or rubbing of eyes
  • Use artificial tears to prevent dryness


  • To be avoided

Any hard item, tough to bite or chew.

Heavy meals and difficult to digest foods – cause indigestion.

Junk foods- cause a disturbance in digestion and reduces the bioavailability of the medicine

Carbonated drinks – makes the stomach more acidic and disturbed digestion

Refrigerated and frozen foods – causes weak and sluggish digestion by weakening Agni (digestive fire)

Milk and milk products – increase Kapha and cause respiratory problems

Curd – causes vidaaha and thereby many other diseases
