[Measurement of accommodation using optical biometry]

open access: yesDer Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2008
BACKGROUND: Making 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

Prevention and correction of residual refractive errors after cataract surgery

open access: yesJournal of Clinical Ophthalmology and Research, 2017
Cataract surgery today has become more of a refractive surgery with high patient expectations and demand for independence from glasses. With advances in biometry, precise intraocular lens (IOL) power calculation is the most important step in achieving ...
