Аннотация

Subject of research: The object of the study were 198 patients (198 eyes). The subject of study was brown cataract. Purpose of work: To improve technology of laser extraction of brown cataract by changing technological stages of facofragmcntation. Methods of research: visometry, perimetry, autokcratorcfraktomctry, biomicroscopy, keratotopographieal method, pahimetrieal studies, the method of laser cataract extraction, the method of ultrasonic facocmulsification of cataract. The results obtained and their novelty: For the first time reveal the dynamics of keratotopographieal changes in laser extraction of the brown cataract. The decline of the number of injuries capsular bag when applying capsulorcxis oval form in comparison with traditional capsulorcxis of round form. Revealed advantages of the “peripheral laser fragmentation by optimizing the power and frequency of the laser”, which consists in reducing the total laser energy and reduce the duration of the operation. We prove the benefits of improved techniques of laser extraction of brown cataracts in comparison with traditional methods, which consists in reducing operating and postoperative complications, improve visual function in the postoperative period. Practical value: the use of keratotopographieal maps to determine the optimal location of the operating time of cut and paracentesis. Optimization of power and the laser frequency can reduce the total amount of energy and reduce the injury of operation. Advanced Laser extraction of brown cataracts can reduce the number of operative complications and provide a more wounds, its recovery of visual functions and hence the total disability. Degree of embed and economic effectivity: results arc implemented in practice of eye diseases department in TMA and Ophthalmic Clinic “SHIFO NUR KOZ”. Field of application: healthcare, ophthalmology.
