Comparison of central corneal thickness estimated by an ultrasonic pachymeter and non-contact specular microscopy

Arq. bras. oftalmol; 79 (5), 2016
ABSTRACT Purpose: To compare central corneal thickness (CCT) measurements of healthy individuals obtained with ultrasonic pachymetry (UP) and non-contact specular microscopy (NCSM). Method: In total, 148 eyes of 74 subjects with no ocular or systemic diseases were included in the study. Central corneal...

Perfil paquimétrico horizontal para a detecção do ceratocone

Rev. bras. oftalmol; 74 (6), 2015
RESUMO Objetivo: Avaliar a capacidade de dados de perfil paquimétrico horizontal, a fim de distinguir o ceratocone de córneas normais, e comparar a precisão de índices com outros tomográficos mais complexos. Métodos: Em um estudo retrospectivo, um olho selecionado aleatoriamente de 225 pacientes co...

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 ...

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...
