Addictive treatment of keratoconus with collagen crosslinking after Ferrara ring implant
DOI: 10.1590/S0034-72802009000300004
PURPOSE: To describe our experience with crosslinking after Ferrara ring implant for better vision and corneal stabilization. METHODS: six patients with age of 26 – 38 years old had treatment with crosslinking after Ferrara ring implant. Five patients had 2 ring segments implanted and one patient had one segment implanted. After 4 to 55 months the patients were submitted to crosslinking with UVA light according to Seiler et al protocol. RESULTS: Four eyes had progressive alteration of refraction and 2 patients had no alteration of refraction. The topography showed flattener curvature and at the slip lamp 100% of the eyes had good depth after one year post operatively. The specular microscopy didn’t show any significant alteration and the visual acuity was similar before the procedure. CONCLUSION: The crosslinking may help to maintain stable keratoconus, not only in progression cases, but also in evolutive keratoconus with ring implant.
