METHOD extracapsular cataract extraction combined with congenital iris coloboma With intracapsular intraocular lens implantation and INTROOKULYARNAYA LENS FOR IMPLEMENTATION

摘要

1. A method for extracapsular cataract extraction combined with congenital coloboma of the iris with intracapsular implanting an intraocular lens (IOL), comprising holding two paracentesis, operational tunnel incision, the superposition of two or more iris retractors, front circular capsulorhexis, extracapsular removal of the lens nucleus and its mass by ultrasound phacoemulsification or laser and implantation of an intraocular lens, characterized in that the implantation of an IOL produced after removal of lens mass according to claim 2, wherein the optical portion of the IOL is installed in congenital coloboma zone, centering it with the center coloboma, wherein the edge of the optical portion abuts the equator of the capsular bag, and a support member mounted in its opposite kray.2. An intraocular lens comprising an optical portion and a support member lying in its main plane and symmetrical about the main axis and arranged in a closed loop, characterized in that the angular distance between the attachment points of the support member to the end face of the optical part is equal to 90 °, and in the top of the loop petelechka formed, the vertex of which is directed toward the optical portion, the ratio of the average diameter of the optical part to a distance between the optical center and the point on the loop maximally remote from it, is in the range from 0.5 to 0.8.
