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: To assess the efficacy of topical cyclosporine .05% for preventing endothelial loss in cornea transplant. METHODS: Retrospective study of 18 eyes submitted to penetrating transplant due to keratoconus, operation carried out by the same surgeon. Patients with specular microscopy with lower than or equal to 1200 cells/mm2 belonged to the control group. The inclusion criterion was the occurrence of specular microscopy in the postoperative period over the 6- month, 1- year, and 2- year periods and the exclusion criterion […]

PURPOSE: To analyse the corneal astigmatism after transplantation as well as to demonstrate how post-surgical handling of sutures affects the refractive and visual outcome in patients submitted to cornea transplantation by keratoconus with three to six years of follow-up. METHODS: Non-controlled longitudinal observational secondary clinical study. Fifty records of patients submitted to penetrating keratoplasty between 2000 and 2002 have been reviewed, including 50 eyes of 50 patients operated under the same surgical technique by the same surgeon. Follow-up time ranging […]
