METHOD OF IMPLANTATION AND SUTURE FIXATION OF TRIPARTITE S-CURVED INTRAOCULAR LENS TO IRIS Russian patent published in 2010 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, more specifically to ophthalmosurgery and can be used in the implantation of a S-curved intraocular lens (IOL), e.g. Acrysof, with the suture fixation to the iris on eyes without a capsular support. After preliminary myosis, the lens is implanted through a small tunnel incision by bringing supporting elements behind the iris to be anchored thereafter. At first, it is one supporting element that is brought behind the iris with the second one to be kept in the tunnel incision. The brought supporting element is sutured to the iris. Then the remained part of the lens is brought behind the iris. An instrument, e.g. a hook, is brought closer under an optical part of the lens that is centered by pressing the optics upwards; the second supporting element is sutured. The sutures are at 2.5-3.5 mm from a pupil edge with a stitch length maintained to be 1-1.5 mm.

EFFECT: method allows making a round pupil and keeping an irising function in the postoperative period that is expressed in preserved normal reaction of a pupil to light, ensured good cosmetic effect and reduced length of operation.
