Analysis of low-energy and high-frequency femtosecond laser for the construction of deep anterior donor corneal lamellae

Rev. bras. oftalmol; 73 (2), 2014
Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick ...

Assessing ectasia susceptibility prior to LASIK: the role of age and residual stromal bed (RSB) in conjunction to Belin-Ambrósio deviation index (BAD-D)

Rev. bras. oftalmol; 73 (2), 2014
Purpose: To compare the ability to detect preoperative ectasia risk among LASIK candidates using classic ERSS (Ectasia Risk Score System) and Pentacam Belin-Ambrósio deviation index (BAD-D), and to test the benefit of a combined approach including BAD-D and clinical data. Methods: A retrospective nonran...

Comparison of clinical outcomes between limbal relaxing incisions and toric intraocular lenses in eyes with astigmatic corneas

Rev. bras. oftalmol; 73 (1), 2014
Objective: To compare refractive and vectorial outcomes of limbal relaxing incisions (LRI) versus toric intraocular lenses (IOL) in the treatment of preexisting corneal astigmatism at the time of phacoemulsification. Methods: This longitudinal observational case series assessed 62 eyes of 31 consecutive ...

Implante de segmentos de anel estromal em ceratocone: resultados e correlações com a biomecânica corneana pré-operatória

Rev. bras. oftalmol; 71 (2), 2012
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...

Repeatability of central corneal thickness measurement with the Pentacam HR system

Rev. bras. oftalmol; 71 (1), 2012
PURPOSE: To assess the repeatability of central corneal thickness measurement at the geometrical center (Central Corneal Thickness - CCT) given by the Pentacam High Resolution (HR) Comprehensive Eye Scanner (Oculus, Wetzlar, Germany) over time. METHODS: Prospective, single center, observational study. Tw...

Análise da ceratometria corneana em pacientes portadores de espasmo hemifacial

Rev. bras. oftalmol; 70 (6), 2011
OBJETIVO: Determinar a variação da ceratometria em olhos de pacientes portadores de espasmo hemifacial submetidos a tratamento com toxina botulínica. MÉTODOS: Foram incluídos 18 pacientes portadores de espasmo hemifacial que foram submetidos ao exame oftalmológico completo, além da topografia corn...
