The A method is an ultrasonic one-dimensional scan that allows you to obtain a graphic image of the structures of the eye 👁 The principle is based on the partial reflection of ultrasonic waves from structures and their registration in the form of peaks. The distance between the peaks depends on the time of passage of the sound wave to the surface of the intraocular structures and back to the emitter 📈 The height of the peak is proportional to the sound density of the tissu
When you have a patient with dense cataract you are facing multiple challenges performing eye examination. Optical biometers will not be able to provide an AXL, Slit lamp examination could be limited as well... The only solution to complete eye examination is to use ophthalmic ultrasound. Ultrasound biometer will allow you to measure AXL even is cataract is too dense. B-scan will provide detailed image of the back of the eye UBM will provide detailed image of anterior segment
