FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely ophthalmosurgery. For cataract extraction in patients with pseudoexfoliation syndrome, tunnel incision and paracentesis are formed, introduction of mydriatic and viscoelastic anterior chamber, anterior capsulorhexis, crystalline lens fragmentation by femtosecond laser radiation, phacoemulsification of produced fragments by ultrasound, implantation of intraocular lens into capsular sac, followed by washout of the viscoelastic from the capsular sac and the anterior chamber and the pseudoexfoliation deposits from the anterior chamber angle. Patient undergoes preoperative preparation one day before the operation by double installation of a mydriatic, a non-steroid anti-inflammatory agent and an antibiotic or antiseptic, anterior circular capsulorhexis with diameter of 4.5–5.5 mm is performed using femtosecond laser energy 5,000–5,200 nJ, then using laser radiation power 7,600–8,500 nJ, depending on nucleus density, nucleus lens is fragmented by pattern in form of eight radial femtoreses. Further, after making a limbal tunnel with width of 1.8–2.2 mm and two paracenteses at 9 and 3 o'clock, a combined viscoelastic comprising a dispersed and cohesive viscoelastic is introduced into the anterior chamber, and the hydrochor is carried out along femtoreses and sparing hydrodissection without rotation of the nucleus of the crystalline lens. Further, the capsular sac is stabilized by three additional iridocapsular retractors through the additional paracenteses, wherein phacoemulsification of lens is carried out in sparing hydrodynamic mode. After the ultrasonic stage is completed, an intracaspius ring is implanted through the injector, and the primary posterior capsulorhexis is performed before or after the intraocular lens implantation.
EFFECT: method improves efficiency and reduces by-effects of the operation by reducing the volume of intracapsular manipulations, reducing load on the ligamentous capsular apparatus of the lens.
