Clinical study of keratoconus in central Kentucky.

Keratoconus is an ectatic corneal disorder that results in a central or inferior conelike anterior protrusion. This results in irregular myopic astigmatism, causing considerable visual impairment. We have completed a retrospective clinical study of keratoconus in the central Kentucky area. When compared to other national studies of keratoconus, our study patients generally had more severe disease at the time of diagnosis and had a higher rate of keratoplasty. Keratoconus treatment is highly successful, and early diagnosis is warranted to prevent unnecessary visual loss.
