L'intérét de la topographie cornéene dans le choix de la lentille rigide perméable aux gaz

Abstract

Corneal topography plays a critical role in clinical decision-making when fitting rigid lenses and a thorough understanding of this area is essential to ensure success and patient comfort. By examining corneal topography, practitioners can assess the regularity of the cornea, detect irregularities and abnormalities such as corneal astigmatism, and identify areas of high or low curvature. This detailed information allows for the personalized fitting of rigid lenses, minimizing potential complications such as discomfort, visual aberrations, and damage to the cornea.There are two types of topography: the specular topography and the elevation topography. The results of the two topographies are different because each has its operating principle. Specular topography is the closest to the actual results; on the other hand elevation topography is used to detect an irregular cornea and refractive surgery.
