FIELD: medicine.
SUBSTANCE: nucleus of lens is fragmented completely by femtosecond laser light at power 7,000-8,500 nJ; that is followed by making a corneal flap incision, dilating the pupil mechanically, and separating the synechias. A continuous circular capsulorhexis is performed, and the fragmented crystalline substance is emulsified. If observing degree II nuclear density, the nucleus is fragmented on 8 segments, while degrees III and IV requires fragmenting the nucleus on 8 segments in a combination with the circular incision in the centre 3 mm in diameter.
EFFECT: method provides creating the optimum conditions for phakoemulsification of the crystalline lens in the narrow rigid pupil and iris-lens synechias for enabling the adequate fixation of the IOL in the capsular sac with reducing intraoperative injuries and preventing the complications.
