Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For conducting ultrasonic cross-linking in progressive keratoconus in patients with initial corneal thickness at apex of cone ≤ 400 mcm after deepithelialization, a patient's corneal thickness is measured by intraoperative optical coherence tomography (OCT). Corneal protector solution used is dextralink, which is instilled onto the patient's cornea for 30 minutes. After that, in the course of repeated OCT, the corneal pachymetry is determined in the thinnest place and the protective cornea protective flap thickness is calculated as difference between 400 mcm and the minimum pachymetry value of the patient's cornea according to the repeated OCT data. At that, to obtain a protective flap of a layer of the anterior donor stroma of the native donor cornea, which is resected with a femtolaser, of the required thickness with diameter of 9.4 mm, a donor sclerotic strain disc is used, isolated by means of a femtoscopic laser from a native cadaver's eye, pre-used in parallel to femtoscopic posterior layer keratoplasty or Descemet's membrane transplantation on one operation day. After the femtosecond resection of the native donor corneal stroma layer and obtaining a protective flap, it is separated from the underlying tissues, laid on the patient's corneal surface and centered. That is followed by the control intraoperative OCT of the "patient's cornea - donor cornea stroma flap" complex to confirm the total thickness of at least 400 mcm. Then ultraviolet irradiation is carried out patient procedure through the protective corneal stroma of a donor cornea flap wavelength 370 nm capacity of 9 mW/cm 2  for 10 minutes with parallel dextralink instillation every 2 min. After irradiation, a protective flap of donor cornea stroma is removed. 
     EFFECT: method provides the safe procedure of ultraviolet cross-linking by replenishing the corneal thickness deficiency of the patient to the required value taking into account individual values of patient's thin corneal pachymetry, absence of intra- and postoperative complications, strengthening of strength properties of the cornea, stopping and absence of keratoconus progression in the remote postoperative period.

Abstract: FIELD: soil or rock drilling; mining. 
     SUBSTANCE: invention relates to physical and mechanical testing of materials, particularly rocks, can be used in engineering-geological survey and provides determination of ultimate strength of material at compression without destruction of sample. Essence: indenter of variable cross-section is continuously pressed with continuously increasing load to maximum value of arbitrary value, after which the impression is stopped and sample is unloaded to zero value. Magnitude of the load and the corresponding displacement depth of the indenter are recorded, and the pressure on the contact surface between the indenter and the sample is calculated in the period of increasing load. Indenting and unloading of the indenter is performed without changing its position in a cyclic manner, providing in each subsequent cycle a discrete increase in the maximum load value at which unloading begins. During sample unloading, pressure is determined on contact surface by ratio of load on indenter to maximum area of contact surface in each cycle. In each cycle, also for the same depth of the indenter displacement, the difference between the pressure on the contact surface during the load increase and the pressure during the unloading period is calculated, and the maximum value of the difference of the said pressures is determined. Tests are continued until formation of horizontal section on graph of relationship between maximum values of pressure difference and corresponding load values. Value of pressure difference corresponding to horizontal section is taken as ultimate strength of material at compression loads. 
     EFFECT: technical result is possibility of determining ultimate strength of material during compression without destroying sample.
