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 […]

PURPOSE: Assess the clinical and topographical effects of corneal collagen crosslinking in patients with keratoconus on Brazilian population. METHODS: Thirty seven eyes of 37 patients (22 female and 15 male) with diagnosis of progressive keratoconus and corneal paquimetry higher than 395 micra, were treated with riboflavin and ultraviolet A radiation, over 30 minutes, to induce corneal collagen crosslinking. Keratometric values were compared as well as the best corrected visual acuity, before and after the procedure, with ranges of 40 and […]

PURPOSE: Demonstrate the possibility of changing the biomechanical behaviour of cornea stroma by usage of riboflavin associated with non-ultraviolet light. METHODS: Double blind prospective study. Twenty five porcine eyes enucleated 24 hours before the experiment, have been divided on the following groups : Riboflavin 0,1% with irradiation of blue light, Riboflavin 0,1% without irradiation of light , Riboflavin 0,5% with irradiation of blue light, Riboflavin 0,5% without irradiation of light and BSS with irradiation of light. RESULTS: Differences where noticed […]
