Corneal ectasia of debated etiology, keratoconus, leads to thinning and deformation of the cornea's curvature, which assumes a "conical" shape, with the appearance of high irregular astigmatism and consequent decrease in visual acuity. Keratoconus is always bilateral and asymmetrical, being noticed in adolescence.

Ceratocone
Doença progressiva que causa afinamento e protrusão cônica da córnea, resultando em visão distorcida. O Anel de Ferrara estabiliza e regulariza a curvatura corneana.
Astigmatismo
ASTIGMATISMO PÓS TRANSPLANTE DE CÓRNEA
Astigmatismo residual elevado após transplante de córnea. O Anel de Ferrara pode reduzir significativamente esse astigmatismo.
Lasik
ECTASIA PÓS LASIK
Complicação rara após cirurgia refrativa que causa afinamento e protrusão da córnea. O Anel de Ferrara é uma opção terapêutica eficaz.
DMP
DMP – DEGENERAÇÃO MARGINAL PELÚCIDA
Ectasia corneana periférica inferior que causa astigmatismo irregular severo. O implante do anel melhora a regularidade da superfície corneana.

FERRARA RING
Available in two versions, the Ferrara™ Premium Ring is made of Yellow PMMA (polymethyl methacrylate – the same material as intraocular lenses), which creates a complementary filter to blue light, predominantly found at night, that can cause halos and glare.
HIGH SATISFACTION RATE
As an orthopedic technique, the Ferrara Ring corrects corneal deformities by restoring its physiological curvature. After surgery, residual refractive errors can be corrected with conventional optical corrections or contact lenses.
STABILITY
In 85% of cases, the Ferrara Ring™ implant stabilizes the progression of keratoconus and allows for adequate vision correction with the use of contact lenses or glasses.
