FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely ophthalmology and may be used for surgical management of a dense nucleus lens dislocation into the vitreous cavity (VC). What is involved is a lens phacoemulsification from an anterior approach. The operation is started with forming two corneal microincisions. That is followed by a vitrectomy combined with lens separation from the VC fibres from a three-port approach into: a flat portion of a ciliary body using the system 25 or 27G. A perfluororganic compound is supplied to an optic disk in the amount of 1/5-1/4 VC; a videotom is used to remove a capsule of the lens surfacing the PFOC. Thereafter, the lens nucleus is set on a distal end of a light guide by 2/3 nucleus depth with the nucleus to be divided into a lesser and greater zones and to be brought to the iris. Then, the vitreotom is brought out, and a head of an ultrasonic phacoemulsifier from the anterior approach, and that is followed by the repeated phacoemulsification started from a most remote zone from the light guide by moving a working end of the phacoemulsifier through an arc; the nucleus is emulsified in layers thereby approaching the light guide. As often as the residual nucleus fragment drops onto the PFOC, it is re-set on the distal end of the light guide on the initial principle. After the nucleus has been removed, the vitreotom is used to remove the residual lens mass. The intraocular lens is implanted and fixed from the anterior approach. The PFOC is replaced by normal saline.
EFFECT: method provides reducing the timing of surgery and injuries.
