FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used in intraocular correction of planar-haptic intraocular lens (IOL) aphakia in phacoemulsification of cataract complicated by rupture of the posterior capsule of crystalline lens. The method provides partially endo- and partially supracapular lens fixation at the diametrical edges of circular capsulorhexis by clippling them in graduated slots formed in haptic elements of the IOL and created at surgery from each lateral edge of each haptic element in its proximal portion. The slots are represented by four rays symmetrical with respect to a central longitudinal axis of the IOL and directed to the centre of an optical portion of the lens. The slot length is graduated considering the anterior continuous circular (ACC) diametre, while the IOL is fixed in such a manner that a part of the proximal ends of the haptic and optical portion of the lens are arranged on the anterior capsule of the crystalline lens. ^ EFFECT: method allows reliable and atraumatic fixation of the presented IOL by the edge of anterior continuous circular capsulorhexis in extensive defects of the posterior leaf of capsular sac of the crystalline lens. ^ 2 dwg |
