FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, and more specifically to ophthalmology. After delivering an IOL into the anterior chamber, two diametrical corneal paracenteses follow. A threaded long curved needle is stuck in the cornea through the first paracentesis and stuck out through sclera within a projection of the ciliary furrows oppositely from paracentesis. The thread ends are left outside. A hook is introduced through the second paracentesis, and the threaded needle is introduced from the first paracentesis into the second paracentesis. The second threaded long curved needle is used to perform described procedures through the second paracentesis. One of haptic elements is delivered outside through one of paracenteses and fixed with the thread delivered through the same paracentesis. Similarly, the other diametrical haptic element is handled. The IOL is implanted into the posterior chamber with aligning the thread ends delivered within a projection of the ciliary furrow, and fixing the thread ends to sclera. According to another version, after delivering the IOL into the chamber, performing two diametrical corneal paracenteses, one haptic element is delivered outside through the first paracentesis, then the threaded long curved needle is used with fixing the thread end to the delivered haptic element, further, the haptic element is reset in the anterior chamber with the thread fixed thereto; the needle is stuck in the cornea through the first paracentesis and stuck out through sclera within a projection of the ciliary furrows oppositely from paracentesis, thus the thread end with the needle delivered within a projection of the ciliary furrow is left outside; further, the second haptic element is delivered outside through the second paracentesis, thereafter the second threaded long curved needle is used to perform the same procedures through the second paracentesis, then the IOL is rotated around in the anterior chamber, and the IOL is implanted into the posterior chamber with aligning the thread ends delivered within a projection of the ciliary furrows, and fixing the thread ends to sclera. The assigned task is realised by two developed versions for treating the dislocated IOL to ensure the same technical effect. ^ EFFECT: reduced number of postoperative complications, such as astigmatism and IOL decentration. ^ 2 cl, 2 dwg, 2 ex |
