Purpose: : To evaluate the potential of Artemis high-resolution ultrasound (US) in diagnosis of corneal anomalies in the context of other imaging techniques, including conventional ultrasound biomicroscopy (UBM) and anterior segment optical coherence tomography (AS-OCT).

Methods: : Five eyes from three postrefractive patients were scanned using the Artemis-2 in a series of meridians along each clock-hour. The echo data were then processed and B-mode images and thickness maps of the epithelium, flap and residual stromal bed layers were generated.

Results: : In our series, Artemis was able to detect anomalies in the cornea of postrefractive patients not seen by usual examination methods or other imaging techniques such as UBM or AS-OCT. One patient postLasik for myopia presented a refractile particle (debris) in the interface and three areas of Bowman disruption were identified. Another patient had a significant paracentral corneal thinning with a residual thickness of less than 250 microns. Precision of Artemis measurements is on the order of 1 to 5 µm and the resolution of its images ranges is 35 µm axially by 65 µm laterally.

Conclusions: : The detailed, high resolution three-dimensional mapping by Artemis digital US provides a unique tool in the diagnosis and management of refractive surgical complications. Artemis was able to diagnose the causes of refractive surgical inaccuracy in particular cases.
