FIELD: medicine.
SUBSTANCE: invention is related to medicine, in particular, to ophthalmology, and intended to determine intervention approach during cataract phacoemulsification. After pre surgical determining lens density by estimation of lens echodensity during ultrabiomicroscopy with the help of colour mapping function and E-GAIN signal amplification using Sonomed apparatus, comparative estimation of the obtained lens density with threshold value equals to 35 dB is performed. If the lens density is more than 35 dB, possible difficulties with lens crushing and removal are stated, and the intervention approach is used with high degree of lens density.
EFFECT: method enables improving the therapeutic effect, preventing possible complications.
