Pseudophakic correction factors for optical biometry
Graefe's Archive for Clinical and Experimental Ophthalmology, 2001The IOLMaster of Carl Zeiss Jena, which has recently become available, is a combined instrument for biometry and intraocular lens (IOL) planning for cataract surgery utilizing partial coherence interferometry for measuring axial length. Whereas measurement data from classical ultrasound biometry, e.g.

Ultrasonic biometry of the optic nerve diameter
Orbit, 1986The results of the authors' echographic biometry of the optic nerve diameter agree with the different pathophysiological conditions. the method is especially helpful in diseases with secondary changes of the optic disc, such as swelling or atrophy. It gives special information through follow-up in neuritis or optic nerve compression.
