FIELD: medicine.
SUBSTANCE: according to the first version, if only one nucleus fragment is preserved in a capsular sac by the time of posterior capsular rupture, the residual nucleus is removed by phacoemulsification ensured by introducing a cohesive viscoelastic behind the nucleus fragment into an anterior vitreal cavity with recovering normal eye tone; it is followed by bringing the nucleus fragment close to an end face of an ultrasound tip by means of an instrument and held there to create complete occlusion, then emulsified with a balanced saline bottle kept at a height minimal yet enough for phacoemulsification. According to the first version, if two nucleus fragments are preserved in a capsular sac by the time of posterior capsular rupture, the cohesive viscoelastic is introduced behind the nucleus fragments into the anterior vitreal cavity with recovering normal eye tone; thereafter the smaller fragment is brought onto an iris in the area of angle of the anterior chamber within paracentesis; while the other fragment is brought close to an end face of an ultrasound tip by means of an instrument and held there to create complete occlusion, then emulsified with the same instrument used for holding the smaller fragment simultaneously within angle of the anterior chamber; the smaller fragment is placed back to the capsular sac and removed; the balanced saline bottle is kept at a height minimal yet enough for phacoemulsification.
EFFECT: method enables completing the operation following extensive injury of posterior capsule by phacoemulsification without enlarging a primary incision; it provides reducing intra- and postoperative complications, ensures fast rehabilitation of the patients and reduced length of the operation.
