Abstract
Objetivo: Avaliar a ação do anel corneano intra-estromal de Ferrara no tratamento da ectasia corneana pós Excimer Laser. Métodos: O anel de Ferrara, que já vem sendo aplicado no tratamento do ceratocone, alta miopia e astigmatismo irregular, foi utilizado para estabilizar e corrigir a ectasia corneana de dois pacientes submetidos à PRK. Resultados: Após o procedimento cirúrgico, foi observado um aplainamento da córnea central de aproximadamente 6 dioptrias no 1º caso e de 10 dioptrias no 2º, com melhora na acuidade visual. Os resultados vêm se mantendo estáveis até o momento. O tempo de seguimento pós-operatório foi de 3 e 8 meses, respectivamente. Conclusões: Anel de Ferrara obteve sucesso no difícil tratamento desta complicação cirúrgica, permitindo que se retarde ou até mesmo se evite a evolução destes casos para um transplante de córnea com todos os seus riscos, lenta recuperação e dependência da agilidade das filas de doações.
Purpose: To evaluate the action of Ferrara's Ring in the treatment of corneal ectasia after Excimer Laser. Methods: Ferrara's Ring, that is already being applied in the treatment of keratoconus, high myopia and irregular astigmatism, has been used to stabilize and to correct the corneal ectasia of 2 patients submitted to PRK. Results: After the surgical procedure, a flattening of the central cornea was observed, with approximately 6 D (first case) and 10 D in the second, with visual acuity improvement. The results have remained stable until this moment. The postoperative follow-up was of 3 and 8 months, respectively. Conclusions: Ferrara's ring has obtained success in the difficult treatment of this surgical complication, allowing delay of or even avoiding the evolution of these cases to a corneal transplantation with all its risks, slow recovery and dependence on the agility of the donation lines.
