Ultrasound system for corneal biometry

The Journal of the Acoustical Society of America, 1995
An ultrasonic biometer images an eye structure and enables measurement of a cornea's thickness at various points about the cornea's surface curvature. The biometer employs a liquid bath in contact with the corneal surface and includes a curved track positioned above the liquid bath, the curved track having a path that closely approximates the surface ...
