FIELD: medicine, ophthalmology.
SUBSTANCE: in case of nuclei up to 8 mm in diameter due to an ultrasound tip one should form a groove for the whole diameter of a nucleus. In case of nuclei being above 8 mm in diameter with the help of an ultrasound tip one should form two perpendicular grooves. Remained parts of nucleus should be removed mechanically with the help of pincers. The innovation provides increased efficiency of surgery of cataract due to possibility to remove large-scaled dense nuclei through small-sized incision at minimal traumatism for ocular tissues and, also, shorten the period of ultrasound impact and duration of operation.
EFFECT: higher efficiency.
