[Axial echometry of the eye. Results and possible clinical applications].

This survey describes ultrasound measurement techniques and echograms of living phakic and cataract eyes. Results of clinical echometry on emmetropic and ametropic eyes are reported. In unilateral or bilateral cataract and in unilateral aphakia, appropriate ultrasound measurements are of fundamental importance for restoring compatible vision; in unilateral aphakia, by means of combinations of contact lenses and spectacles; in cataract, by means of precalculated artificial intraocular lenses.
