Pentacam is a noteworthy invention that helps obtain images of the surface of the cornea and identify corneal abnormalities, if any. It is a 3D imaging tool, and the photographs obtained help determine the candidates who are suitable to undergo LASIK. It is a contactless procedure that is highly efficient in assessing the condition of the eyes, mainly in the corneal region.
