FIELD: medicine.
SUBSTANCE: device consists of handle and working part. Working part consists of working segment, holder, first knee and second knee. Upper edge of working segment is made flat, lower edge is made rigid and sharp. External lateral side of working segment consists of three sections. Method includes introduction of working segment of device through paracentesis. Working segment of device is introduced through paracentesis into anterior chamber, filled with viscoelastic, in circumference arch clockwise. After that device is fixed with lower rigid sharp edge to anterior capsule of lens according to lens centre. After that through main corneal incision introduced is capsule forceps and capsule is punctures in the centre of lens with formation of valve. Valve is gripped with forceps and line of capsule rupture is brought to place where working segment is connected with second knee, after that rupture of capsule on rigid lower edge is performed, bending capsule over upper edge of working segment upwards and outwards. Edge of capsulorexis is brought to edge of free end of working segment. Device is removed on circumference arch counterclockwise. Into the same paracentesis second device is introduced and installed in accordance with lens centre in such a way that free end of working segment matches the edge of formed earlier capsulorexis and carrying out of remaining part of capsulorexis is continued according to described above method, starting from free end of working segment.
EFFECT: application of claimed group of inventions allows to increase quality of cataract phacoemulsification due to performing capsulorexis of strictly specified size and location.
