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.

Acta Ophthalmologica
Ocular biometry is a diagnostic method in ophthalmology that uses various techniques to measure the different parts of the eye. It involves the use of instruments that can measure the axial length of the eye, corneal curvature, anterior chamber depth, and other parameters related to the eye's structure.

[Measurement of accommodation using optical biometry].
Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2008Making accommodation possible for all age groups is a topic of great interest. We applied optical biometry in order to study the physiological mechanisms in detail. Longitudinal relations in the optical axis were measured during accommodation in volunteers of different ages and lens states.A total of 60 subjects (children, adolescents, adults, and ...
