Keratoconus (also known as Pellucid) is a progressive non-inflammatory disorder that causes a characteristic thinning and cone-like steepening of the cornea. This steepening results in distortion of vision, increased sensitivity to glare and light and an associated reduction in visual acuity. These symptoms usually appear in the late teens and early twenties.

Keratoconus may progress for 10-20 years or even longer.  It can slow down and pick up again quickly – Keratoconus has a “mind of its own.” 

(Note: as keratoconus and pellucid are the same disease process, any reference to “keratoconus” on this site also applies to “pellucid” as well.) New research shows Keratoconus occurs in 1 in 500, here are some of the symptoms you may experience:

  • BLURRED VISION
  • DOUBLE VISION 
  • POOR NIGHT VISION
  • FREQUENT EYE RUBBING
  • GLARES OVER LIGHTS/HALOS
  • FREQUENT PRESCRIPTION CHANGES
