Keratoconus

Keratoconus

Keratoconus is a degenerative disorder of the cornea that cause it to thin and change into a more conical shape than its normal spherical one. Keratoconus can cause significant visual distortion and visual loss.

If afflicting both eyes, the deterioration in vision can limit one’s ability to drive and read.

Some forms of keratoconus are mild and picked up incidentally on eye imaging taken as part of laser eye assessments. Many progress in the teenage years and 20’s with increased corneal degeneration, vision loss and corneal scarring. If left untreated the only option in advanced keratoconus is corneal transplantation.

More recently a treatment called corneal cross linking (CXL) has become available to halt the progression of keratoconus and often eliminate the need for corneal transplantation. Many patients with keratoconus find wearing contact lenses becomes more comfortable after crosslinking. If Keratoconus is progressing or affecting your vision you may be a candidate for this treatment. To determine this serial Pentacam images are required to identify progression and response to treatment.

Contact lenses are important in the management of keratoconus both before and after the treatment.
