ABSTRACT

ABSTRACT In this report, we describe a new pupil expander device that was used to obtain adequate pupil dilation and centering in a patient with an iris coloboma. Specifically, we describe the case of a patient with an iris coloboma; a Malyugin ring was inserted to facilitate dilation during phacoemulsifi­cation surgery. One of the scrolls did not engage which resulted in an uneven distribution of forces and an eccentric pupil. A Canabrava Ring was then implanted that promoted effective pupillary dilation and remained stable and effective throughout the surgical procedure.


RESUMO Neste relato, descrevemos um novo dispositivo expansor pupilar que foi usado obter adequada dilatação e centralização da pupila em um paciente com coloboma de íris. Especificamente, descrevemos um caso de cirurgia de facoemulsificação em um paciente com coloboma de íris associado à pupila pequena e que, previamente, tentou-se sem sucesso o uso do expansor Malyugin Ring, que provocou uma dilatação pupilar descentrada. Entretanto, com o uso do expansor de íris Canabrava Ring, a pupila permaneceu dilatada e centrada durante toda a cirurgia, permitindo a realização de um procedimento seguro.
