FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely, to ophthalmology. The anterior capsule is opened; anterior capsulorhexis, hydrodissection, phacoemulsification (PE) of the nucleus of the lens are performed, followed by removing the masses of the lens; an intraocular lens (IOL) is implanted. While forming the anterior capsulorhexis, the anterior capsule is secured using collet forceps, taking the capsule in a fold in the centre and retaining. The anterior capsule is then punctured in the area of the beginning of performing the anterior capsulorhexis using a paracentesis knife; the puncture is expanded with second capsule forceps, beginning to perform anterior capsulorhexis while continuing to retain the capsule with the collet forceps. An iridocapsular retractor is implanted into the created rupture, said retractor securing the capsular bag in this sector. The capsule then stops being retained with the forceps, and the anterior capsulorhexis is continued until the next sector where a second iridocapsular retractor is implanted. Then, after performing the corresponding sectors of capsulorhexis, a third and a fourth ones are implanted, forming an anterior capsulorhexis 4.5 to 5.0 mm in diameter. A capsular ring is implanted into the capsular bag, and PE is performed, the IOL is implanted into the capsular bag, the IOL is sutured to the iris or a Malyugin capsular ring with the capsular bag is sutured to the sclera, followed by removing the iridocapsular retractors and ending the operation.
EFFECT: possibility of forming an anterior capsulorexis of a set size and shape in lens subluxation without risking detachment of the fibres of Zinn's zonule and developing intraoperative complications, thereby increasing the effectiveness of intervention.
