ABSTRACT Homocystinuria is one of a group of genetic disorders called inborn errors of metabolism. It is characterized by a deficiency of the enzyme that converts homocysteine to cystathionine. Keratoconus is an ophthalmologic condition characterized by thinning of the corneal stroma, which causes the co...
Abstract We present a case of a 12-year-old patient with advanced keratoconus in both eyes who received a two-staged treatment in the right eye (OD) to decrease keratoconus progression rate and rehabilitate patient's vision. At the initial clinical examination, visual acuity without correction in OD was ...

ABSTRACT Purpose: To report the visual rehabilitation outcomes and complications of patients fitted with mini-scleral rigid gas-permeable (RGP) contact lenses (mini-SCLs) after penetrating keratoplasty. Methods: We retrospectively reviewed 27 eyes (21 patients) that were fitted with mini-SCLs between O...

ABSTRACT Purpose: The optical quality of the interface after deep anterior lamellar keratoplasty (DALK) using the big-bubble technique has been shown to be excellent, leading to results comparable to penetrating keratoplasty. However, there is little in the literature with respect to the controversy sur...

ABSTRACT We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS) that developed after undergoing deep anterior lamellar keratoplasty (DALK). She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore...

RESUMO Objetivo: Conhecer a percepção do paciente após cirurgia de Ceratocone. Métodos: Foi realizado um estudo exploratório descritivo, com abordagem qualitativa. Os dados foram obtidos por meio de entrevistas áudio-gravadas, com pacientes submetidos à cirurgia de ceratocone e as transcrições...
OBJETIVO: describir los resultados de la queratoplastia lamelar profunda en el tratamiento quirúrgico del queratocono en el Servicio de Córnea del Instituto Cubano de Oftalmología "Ramón Pando Ferrer". MÉTODOS: se realizó un estudio descriptivo prospectivo en 7 ojos con queratocono operados de quer...
Objective: We describe a novel spatula and dissector to facilitate the big-bubble technique in deep anterior lamellar keratoplasty (DALK). Methods: A 29-year-old man who was diagnosed with bilateral keratoconus underwent deep anterior lamellar keratoplasty (DALK). After 350μm partial thickness incis...
OBJETIVO: Verificar os resultados da cirurgia de implante de segmentos de anel estromal para ceratocone e as possíveis correlações existentes entre o resultado cirúrgico e o estado biomecânico da córnea no pré-operatório. MÉTODOS: Dezenove olhos de 19 pacientes com ceratocone foram avaliados ant...
