FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to ophthalmology. The dislocated intraocular lens (IOL) is removed, the extracapsular fixation IOL is implanted. In case of dislocation of the IOL, combined with retinal detachment, four ports are installed: three ports with a caliber of 27 G for manipulations in the eye cavity and a fourth port of 29 G for installing a chandelier. Then, using a vitreotome, vitrectomy is performed in full, after which the vitreous cavity is filled with perfluoroorganic compound (PFOC) to the level of retinal rupture. Then, a limbal tunnel incision is made at 10 o'clock with a length of 2.2 mm and the anterior chamber is filled with adhesive viscoelastic. Then, through one of the ports, they enter the vitreal cavity with vitreal tweezers and clamp the dislocated IOL between the branches of this tweezers in the area of transition of the optical part of the IOL to the haptic one. The IOL is brought close to the iris, until it touches it, and with the help of the same tweezers, the IOL is brought out 1/3 into the anterior chamber. It is turned sideways into the anterior chamber, cut into two halves with collet scissors, continuing to hold one of the halves of the IOL with vitreal forceps, while leaving the other half on the iris. Then, a constant supply of irrigation solution is turned on to prevent hypotension, and with collet tweezers, first half of the cut IOL lying on the iris is alternately removed from the eye cavity through the tunnel, and then the remaining half of the IOL; implant IOL RSP-3. After that, using a vitreotome, two basal colobomas of the iris are made so that the haptic elements of the RSP-3 IOL do not overlap them, and PFOC is replaced with air. After that, endolaser coagulation is performed along the edges of the retinal ruptures, silicone oil is injected into the vitreal cavity in air. The operation is completed with the removal of ports and suturing.
EFFECT: method enables microinvasive and safe removal of IOL dislocation into the vitreal cavity without damage to the structures of the anterior chamber of the eye and, at the same time, effective surgical treatment of retinal detachment.
