Keratoconus

The changing shape of the cornea can produce blurred vision with haloes around lights, ghosting or shadowing or images, and sensitivity to light. Keratoconus is frequently associated with eye rubbing and often seen in patients with a history of allergy and eye itch. The condition is often identified by your optometrist if they note a frequently changing glasses prescription; or find it difficult to obtain an accurate glasses prescription for you.

Treatment aims to stabilise the disease and improve vision. It is important to cease eye rubbing and seek treatment for any eye allergy and dry eye disease. If keratoconus is worsening a procedure called corneal crosslinking may be performed to strengthen the cornea. Vision may be improved through appropriate glasses, specialty contact lenses, and in some circumstance’s laser vision correction. Rarely, surgery may be required to replace the cornea in the form of a corneal transplant.
