[Artifacts in A and B-scan echograms following the implantation of artificial lenses]

In the A scan and B scan echogram of the eye and orbit artifacts may arise following implantation of an intraocular lens. Their origin, form, and localization can be explained by means of physics. Reverberation, foreign body, refraction, and absorption artifacts can be distinguished; familiarity with their appearance will avoid erroneous interpretation and results.
