A cornea transplant would be the last resort.
There are non-invasive treatments and less invasive treatments developed in the 1990's.
INTACS are tiny semi-circle rings placed in the layers of the cornea. They are placed over the area that is buldging/steepening to help reduce the irregularity and improve the quality of vision with contacts.
Cornea Collagen Crosslinking with Riboflavin (C3-R or CXL) is a 30 minutes office treatment that strengthens the cornea and stops the progression of keratoconus. This is the most important treatment. The earlier a patient has this procedure the less damage to the eye.
Once the cornea has been stabilized then contact lenses can be worn with more comfort and better quality of vision.
Use the search feature and archives to read about K-conus. since it is a corneal disease lens surgery does not help it.
