FIELD: medicine.
SUBSTANCE: anterior capsulotomy is performed by exposing to femtosecond laser light at pulse strength 6,200-6,500 nanojoules, 4.5-5.0 mm in diameter. The fragmentation is preceded by forming a canal of 1.8-2.2 mm in diameter and 90-95% deep from the lens depth. The nucleus of lens is fragmented as small as possible from the centre to the periphery.
EFFECT: creating the optimum conditions for lens phacoemulsification, adequate IOL fixation in the capsular sac and preventing uncontrolled capsular sac rupture.
