FIELD: medicine; ophthalmology.
SUBSTANCE: intraocular lens is fixed when it is sutured to the iris, a corneal tunnel is formed at 9 o'clock position and four iris retractors are placed at 2, 5, 8 and 11 o'clock position beyond the capsulorhexis edge. The lens is extracted with ultrasound; 2 iris retractors opposite each other at 11 and 5 o'clock position are removed. The residual capsule, stretched between the iris retractors at 2 and 8 o'clock position, is a diaphragm that delimits the anterior chamber from the vitreal cavity. An intraocular lens is implanted, its haptic elements are tucked under the iris in the projection of 11 and 5 o'clock position, and the optical part is located on the stretched capsular bag. Hemming of the supporting elements of the lens is carried out behind the iris. Removal of the remaining 2 iris retractors is carried out from 2 and 8 o'clock position, paracentesis and tunnel are hydrated.
EFFECT: method allows, without additional tools and manipulations, to temporarily fix the intraocular lens behind the iris, also, due to the mobility of the lens, to center it and hem it, which in turn reduces the risk of lens luxation into the vitreal cavity and postoperative decentration of the optical part of the intraocular lens.
