ABSTRACT Purpose To comparatively analyze the intrastromal MyoRing implantation with femtosecond laser (FL) using the standard and optimized technologies in the experiment and based on the long-term clinical-functional results of the patients with keratoconus (KC) at stages II and III. Materials and methods The experimental work was performed on 24 eyes of rabbits. All eyes were divided into six groups according to the method of operation. In the clinical part of the research, the surgical treatment of 70 patients (76 eyes) with KC at stages II and III was done. Depending on the technology of the operation, all patients were divided into two groups. Group I consisted of 29 patients (32 eyes) with KC, in which MyoRing implantation was performed according to the standard, group II consisted of 31 patients (32 eyes) with KC, in which MyoRing implantation was performed according to the optimized technology. Results Higher voltage was required for stretching samples of the second group in comparison with the third and the sixth group in comparison with the fifth group. In group I, during the period of 6 to 36 months the surgery reverses keratometry, corneal thickness above the MyoRing, and posterior corneal elevation. In group II, 12 months after surgery the clinical and functional parameters remained stable throughout the period of observation. Conclusion Greater reduction in corneal biomechanical stability was observed after formation of the intrastromal pocket in comparison with an intrastromal tunnel; a more pronounced increase in the strength characteristics of the cornea was observed after implantation of the ring in intrastromal pocket, compared with implantation intracorneal segments in intrastromal tunnel, and with increasing depth of intrastromal ring implantation. Application of optimized MyoRing implantation technology compared with standard allows more biomechanical parameters of the cornea to improve and reduce the risk of the ring protrusion.

Background. The aim of the present article was to report our experience with the treatment ofpatients with hallux valgus and to perform comparative analysis of the results of the newly proposed and standard methods for its surgical correction. Methods. The data on 70patients (101 feet) with hallux valgus that were operated on between 2011 and 2015 in St. Petersburg Hospital No 2 using the new and standard methods were analysed. The functional assessment (AOFAS score) and X-ray examination were performed preoperatively, 3 and 12 months after the procedure. Comparative analysis between patients undergoing surgical correction by the new and standard methods has been undertaken. Results. We did not find any significant difference between the two groups in mean AOFAS score 12 months after surgery. Nevertheless, the function score of the patients treated by the newly proposed method (79.4±6.5 in 3 months) was significantly better than in those given the standard treatment (72.2±7.6 in 3 months). Mean intermetatarsal angle 12 months after surgery by standard and new methods was 9,7±0,7° and 8,6±0,7° (p<0.05), mean metatarsophalangeal angle 13,6±0,9° and 13,0±1,1° (p<0,05) respectively. Conclusion. According to the data obtained, the original method of hallux valgus surgical correction allows to improve its functional and x-ray results.

For many decades the main goal of oncologists was to increase life expectancy of patients with malignant tumors, without paying due attention to quality of life. Currently, the goals of patients’ treatment with rectal cancer are to cure, to minimize the risk of local recurrence, preserve the normal course of intestine, to optimize it's function and to ensure quality of life. For a long time, the standard surgical treatment of patients with low rectal cancer was abdominoperineal extirpation, but recently sphincterosafing operations have seen a widespread introduction in surgical practice. However, functional results after these types of operations don't always meet the expectations of surgeons and patients. In the postoperative period, patients often develop a syndrome of low anterior resection, characterized by frequent bowel movements, repeated, prolonged and incomplete evacuation of bowel and the imperative urge to defecate. The manifestation of this syndrome can significantly impair the quality of patient's life and reduce to nothing the efforts of the surgeon to preserve the sphincter of the rectum. For surgical correction of low anterior resection syndrome, various types of colonic reservoir anastomoses have been proposed. The purpose of formation of colonic reservoirs is to increase the cumulative function of intestine. However, the existing methods have several disadvantages related to technical complications and the risk of developing evacuation dysfunction, which is the reason for search the new ways of optimization of anastomoses when performing sphincterotomy operations for cancer of the rectum.

The results of comparative analysis of the efficiency between different sorts of the age-related macular degeneration treatment wet form has been presented in the article. There was demonstrated that choosing the treatment tactics in such pathology patients used to consider the clinical form and the stage of the disease. The wet form needs pneumoretinopexy with following of retina laser coagulation. The subretinal fibrovascular membrane is indications for transcilliary vitrectomy with removal of proliferate tissue. The traditional medical treatment of wet form of age-related macular degeneration does not ensure stable clinical and functional results.
