Abstract
AbstractThe ongoing development of the Pentacam, from its origins in 2002 to the latest version (the Pentacam AXL Wave), is described. Today, the Pentacam AXL Wave combines Scheimpflug imaging, partial coherence interferometry, a Hartmann–Shack wavefront sensor and retroillumination. It enables an assessment of the total eye visual performance, including objective refraction and high-order aberration analysis, and a true separation of the internal wavefront from the total corneal wavefront (not possible with Placido technology).The many features of the Pentacam family are illustrated, with specific attention to the IOL power calculation formulas available for unoperated and post-corneal refractive surgery eyes, as well as for eyes requiring toric IOLs to correct corneal astigmatism.
