METHOD OF INTRAOCULAR VISION CORRECTION IN TRAUMATIC MEMBRANOUS CATARACT (VERSIONS)

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, more specifically to ophthalmosurgery, and can be used in the implantation of an intraocular lens in the posterior eye chamber in traumatic membranous cataract. According to the first version, when observing a through traumatic defect 7-9 mm in diametre in the central region of traumatic memranous cataract, supporting elements of a swan-neck intraocular lens (IOL) are fixed to the remained fibrous-changed capsular sac by the consecutive anchoring of one supporting element, lens centering and anchoring of the other supporting element; suturing is performed with the use of a long atraumatic needle which is brought through a primary tunnel incision or corneal paracentesis, directed through a pupil under an attachment point of the supporting element on the fibrous capsule, and when being at 1 mm from a defect edge, pricked out through fibrous tissue, then delivered outside and cut off, and the suture ends are taken to the same approach, knotted to fix the supporting element. By the second version, with no through traumatic defect found in the central region of traumatic membranous cataract, fibrous-changed tissue of the capsular sac of the diametre equal to that of an optical part of the implanted IOL is excised, and the supporting elements of the lens are fixed to the remained fibrous-changed capsular sac by the consecutive anchoring of one supporting element, lens centering and anchoring of the other supporting element, a long atraumatic needle is used that is brought through a primary tunnel incision or paracentesis, and suturing is arranged as close to the lens optics as possible to maintain the distance 1.0-1.5 mm between the pricking in and pricking out points, further the needle is pricked out through the cornea outside and cut off with the suture ends taken to the same approach, knotted to fix the supporting element.;EFFECT: implementation of the offered method by any of versions provides the absence of haemorrhages in the lens anchoring, stable central position of the IOL, and high visual acuity.;2 ex
