METHOD FOR FEMTOSECOND LASER ASSISTED PHACOEMULSIFICATION Russian patent published in 2015 - IPC A61F9/07 A61B18/20 

FIELD: medicine.

SUBSTANCE: invention refers to ophthalmic surgery and can be used for femtosecond laser-assisted phacoemulsification. A pupil centre is placed under a slit lamp on the cornea if the pupil is narrow. The pupil is dilated. A vacuum ring is placed onto the cornea, and a femtosecond laser approaches the eye through the above ring. The laser is adjusted. A central mark of planned capsulorhexis gets matched with the pencil mark on the cornea in the pupil centre. That is followed by femtosecond laser-assisted capsulorhexis following the marks, nucleus of lens fragmentation and corneal incisions, which are then opened by means of microspatulas. A phacoemulsifier is used to remove the laser-fragmented nucleus of lens and crystalline mass. A multifocal IOL is implanted into a capsular sac; the IOL is advanced 0.2-1.0 mm so that an optical part of the IOL is found in front of an elastic border of the capsulorhexis; the optical part of the IOL is clamped in the caplorhexis aperture with the haptic elements of the IOL left behind the capsulorhexis aperture in the capsular sac. An anterior chamber volume is refilled, and the incisions are sealed by hydrating with balanced physiological solution. A glucocorticoid preparation and an antibiotic solutions are administered subconjunctivally.

EFFECT: method enables reducing the number of injuries and providing the precise centring of the IOL.
