PRK em olhos com topografia atípica e pentacam normal PRK in eyes with atypical topography and normal pentacam

Revista Brasileira de Oftalmologia, 2013
OBJETIVO: Avaliar a segurança do PRK em olhos com topografia de córnea atípica, porém sem características de ceratocone no Pentacam. MÉTODOS: Foram analisados dados de pacientes submetidos à PRK que apresentavam topografia corneana atípica e tomografia normal no pré-operatório. A amostra foi composta de dezenove olhos de dez pacientes.

Repeatability and concordance of the Pentacam system: comparative study of corneal parameters measured with Pentacam and Atlas

, 2008
The purpose of this work is to evaluate the repeatability and concordance of the Oculus Pentacam system when using it for measuring several parameters of the anterior segment of the eye and to check whether this device can substitute a standard corneal topographer in the measurement of the corneal first surface.

Interpretació dels resultats mitjançant el Pentacam

, 2019
El tomògraf de càmera Scheimpflug Pentacam és un aparell amb el qual es pot realitzar un estudi acurat de les estructures anteriors oculars com la còrnia, el cristal·lí i la càmera anterior. L’aparell utilitza una tècnica no invasiva que consisteix en l’obtenció, a partir de cinquanta imatges de forma giratòria en dos segons, una imatge tridimensional ...
