Abstract: Группа изобретений относится к медицине, а именно к офтальмологии, и предназначена для лечения периферических кератоэктазий. Осуществляют формирование интрастромального кольцевого туннеля с помощью фемтосекундного лазера и имплантацию в него донорской ткани. По первому варианту туннель формируют на глубине 80% от минимальной толщины роговицы с наружным диаметром 9,0 мм и внутренним диаметром 3,0 мм. Формирование туннеля завершают выполнением радиальных разрезов роговицы в сильном меридиане, пересекающих туннель. Затем механически через радиальные разрезы проводят расслоение роговицы через туннель и зону истончения в сторону лимба, формируя таким образом интрастромальный карман в зоне истончения роговицы. В созданный карман имплантируют рефракционный донорский лентикул, полученный от другого пациента при процедуре SMILE по поводу миопии, предварительно окрашенный и обрезанный у полюсов или сегмент кольца донорской ткани, полученный с помощью фемтосекундного лазера или выкроенного мануально. После этого в туннель имплантируют один интрастромальный роговичный сегмент длиной дуги от 80 до 359 градусов или два интрастромальных роговичных сегмента длиной дуги от 80 до 160 градусов каждый, располагая их в туннеле диаметрально противоположно друг другу. По второму варианту туннель формируют на глубине 80% от минимальной толщины роговицы, с наружным диаметром 9,0 мм и внутренним диаметром 3,0 мм. формирование туннеля завершают выполнением радиальных разрезов роговицы в сильном меридиане, пересекающих туннель.

Abstract: FIELD: agriculture.  
     SUBSTANCE: invention relates to agriculture and can be used in the cultivation of row crops, namely corn, sunflower, soy, sugar beet. The method for cultivating row crops includes sowing, fertilization, processing of row spacing and strips of the main crop, and processing is carried out on stubble. In the strip under the main crop, simultaneous crevice is carried out with cultivation and fertilization to a depth reached by the roots of the main crop in the phase of 2-3 triple leaves, with cutting off the layer from stubble to the width of the sowing strip with vertical knives, into which seeds and the starting dose of fertilizers are introduced with spear coulters. In the interval between the strips occupied by the main crop, the mulching crop is sown. Further, during the development of the main crop, mulching plants are repeatedly mowed to a height above their growth point so that they do not fall on the strip with the main crop, laying in a roll, processing with a decomposer and rolling, creating a layer that prevents the germination of weeds and provides favorable conditions for the development of the main crop are carried out. Annually, the sowing strip is shifted by the main crop by 1/3 of the width of the row spacing, where due to the created mulching layer, a partial return of nutrients carried away by the main crop into the soil occurs, and the missing elements are compensated by the fertilizers used.  
     EFFECT: increase in the efficiency of cultivation of row crops.
