Since the cornea is responsible for most of refraction, any disruption can cause considerable visual distortion that may not be corrected with spectacles. Individuals with keratoconus require specially designed contact lenses to manage vision.
Keratoconus usually affects both eyes and requires careful contact lens management.
In fact, the lenses simply improve vision while the condition is developing. Emory's contact lens service specializes in managing keratoconus and fitting contact lenses. A specialist evaluates the cornea using sophisticated computerized video keratography to provide a topographical map of the eye's surface. The unpredictable disorder, which in rare cases develops in people over 40, may halt progression at any stage, says Ward. If keratoconus continues to worsen, corneal transplantation may be necessary.
