Keratoconus

kcn

Keratoconus is a weakening of the thick structural layer of the Cornea. This causes a warpage in the shape of a bulge (as shown on the right), so that the Cornea resembles an egg instead of a round sphere. Being the most important lens of the eye, the warpage creates distortion, blur and glare, similar to that of a distorting mirror seen at a circus, and is most noticeable at night particularly whilst driving. Vision is significantly reduced, and some patients become "invisible cripples".

kcnsideKeratoconus is more common in allergy sufferers, and may be worsened by eye rubbing. If severe, the Cornea may become permanently hazy and scarred.Reported estimates of the frequency of keratoconus vary widely between 50 and 230 per 100,000 of population. It occurs in all races, although more frequently in Mediterraneans. Patients are usually first diagnosed with astigmatism, and as sight deteriorates, keratoconus becomes more easily diagnosed. Modern day computerised mapping of the cornea (topography) allows the detection of very early keratoconus called “forme fruste” keratoconus in a so-called "normal eye".

Surgery removes this warpage and distortion which Keratoconus creates. Dr Anthony Maloof specialises in advanced surgical management for keratoconus, including MDALK or Stromal Transplantation and Collagen Cross Linking. Dr Anthony Maloof introduced layered transplantation to Australia in 2000 and has not had any patient develop failure or rejection following this surgery in more than 10 years.
