The article explains how optical coherence tomography (OCT) helps evaluate angles, corneal pathologies, flaps and complications. OCT is a method using light to create a two-dimensional cross-section image of the eye. The two modes to the Visante OCT are standard-resolution imaging and high-resolution imaging. It describes the case of a female contact lens user who had developed a corneal ulcer in her dominant eye.
