TRANSPLANTE DE CÓRNEA EM CERATOCONE: RELATO DE CASO

Abstract

Keratoconus is an uncommon bilateral degenerative disorder, identified by the gradual deformation of the curvature of the cornea, causing a thinning in the shape of a cone, which can be inherited as an autosomal recessive or dominant trait. This study aims to describe a clinical case of keratoconus in which there was surgical intervention for corneal transplantation and discuss the late diagnosis and treatment. Report: Male, 33 years old, diagnosed with keratoconus since he was 19 years old. The initial treatment included the use of soft and rigid lenses, implantation of intrastromal ring segments, implanted in both eyes. Due to the late diagnosis, the disease progressed in the Left Eye (LE), being indicative for corneal transplantation, a procedure successfully performed, but without visual improvement in the LE. Keratoconus evolved in the RE, requiring the Crosslinking surgical technique, stabilizing the disease in the RE. According to the literature, despite the late diagnosis, the only remedial treatment for severe cases is corneal transplantation or keratoplasty, but this report reveals another determining factor for the visual acuity of the EO of the patient in question, which is the need for implant of the IOL for correction of 22 diopters of myopia. In addition, it was possible to demonstrate that, in this case of bilateral keratoconus, the intrastromal ring technique performed in both eyes demonstrated disease paralysis for about 10 years in the RE and without success in the LE
