Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to ophthalmology. One corneal paracentesis – the first paracentesis – is intraoperatively performed for reposition and lining of the intraocular lens. Then the knife is rotated in the lumen of this paracentesis by 10–15 degrees, and pressing the knife on the lower lip of the paracentesis, half the anterior chamber is emptied; then 0.1–0.2 ml of the viscoelastic is injected into the anterior chamber above the zone of the supposed iris puncture. Dislocated intraocular lens is centered by means of a rotary hook. Further, by the same hook, the pupil edge of the iris is translationally displaced by 2–3 mm to the periphery in the four quadrants. First paracentesis with a needle with a suture comes into an anterior chamber. Iris is pierced 1.5–2.0 mm from the pupillary border and the frontal capsule of the crystalline lens capsule passing under the haptic element of the intraocular lens closest to the first paracentesis with a posterior capsule grip. Needle is removed by piercing the cornea until the point of needle transfer into the suture is between the iris and the cornea. Needle prick-out point is the first prick out, displaced relative to the first paracentesis by 90 angular degrees. Then, not completely removing the needle, go over the iris in the reverse direction and withdraw the needle with the suture through the first paracentesis and in its lumen forming a nodular suture. Needle is cut off. That is followed by performing a second paracentesis diametrically opposite the first paracentesis, and the above sequence of needle and needle actions is repeated in a similar manner. 
     EFFECT: method enables improving the uncorrected visual acuity, preserving iris diaphragm function, reducing the risk of postoperative inflammatory reactions, and reducing the length of the surgical intervention.

Abstract: FIELD: medicine. 
     SUBSTANCE: group of inventions relates namely to cardiology, and can be used to predict the development of acute left ventricular failure in the form of alveolar pulmonary edema in patients with acute coronary syndrome. Venous blood is taken from patients into a test tube with 1 drop of a solution (5000 IU / ml) of heparin, which is fixed in a holder. A stirring armature is lowered to the bottom of the test tube and placed in a thermostat with magnets of a magnetic stirrer located under the bottom of the test tube on the bottom wall of the thermostat. The magnetic stirrer is turned on at this point. Then a device - a measuring probe is lowered into the test tube, when the temperature of the sample is stabilized at 37°C, the magnetic stirrer is turned off and the phase angle of the blood sample is measured at a frequency of 120 Hz. If in patients with acute coronary syndrome the phase angle at a frequency of 120 Hz is -55.1° or less, then the development of pulmonary edema is predicted during the first day. If the phase angle from -46.2° to -49.6° is determined in patients with acute coronary syndrome at a frequency of 120 Hz, then its uncomplicated course is predicted.  
     EFFECT: group of inventions increases the accuracy and repeatability of the results of measuring the phase angle of blood impedance due to the blood sample homogenization system available in the device, which prevents erythrocyte sedimentation during the study, and also minimizes the influence of external factors on the research process due to the systems of calibration and self-testing of the impedance meter and sample thermostating in device.
