In the early stages of keratoconus, contact lens fitting or glasses can help patients. As the disease progresses, cornea thinning increases the irregularity of its shape and hinder the improvement once provided by glasses or lenses.
The Ferrara Ring® is a surgical alternative which delays or eliminates the need for corneal transplantation.
Keratoconus may be hard to detect and, habitually, emerges slowly. However, in some cases, keratoconus can progress rapidly. As the cornea shape becomes increasingly irregular, there is gradual vision loss. Glare and photophobia might occur as well.
Keratoconus patients tend to have their lens prescriptions renewed each time they visit their ophthalmologist. Quite frequently keratoconus diagnosis comes late if ophthalmologists are not familiar with such cases and do not identify the early stages of the disease.
Keratoconus is a progressive degenerative condition and can occur at any age in the life of a person. Most of patients are diagnosed early during adolescence, when the disease progresses more aggressively.
Major risk factors are heredity and allergic conjunctivitis normally associated with constant eye rubbing.
