METHOD FOR PRE-OPERATIVE DETECTION OF DEGREE I LATENT DISLOCATION OF LENS Russian patent published in 2015 - IPC A61B3/00 A61B8/10 

FIELD: medicine.

SUBSTANCE: ultrasonic biomicroscopy is used to measure the distance of the lens and corneal endothelium and the distance of the trabecule and iris in the lying and sitting patient. A difference of 0.5 mm and more of the lying and sitting distances of the lens and corneal endothelium is detected. A difference of 0.1 mm and more of the lying and sitting distances of the trabecule and iris is detected. The detected distance differences testify to the presence of degree I latent dislocation of the lens.

EFFECT: reliable and precise pre-operative detection of degree I latent dislocation of the lens ensured by a possibility to measure the depth variations of the anterior eye chamber, iris-lens diaphragm shift, ligament instabilities accompanying postural changes.
