FIELD: medicine. ^ SUBSTANCE: invention concerns ophthalmology and can be used when treating children with Marfan syndrome when the lens equator is visible on edge of a pupil or above pupil edge by 0.5 mm, at diameter of a pupil about 5 mm. Operation is carried out through a corneal tunnel cut and corneocentezises. The corneal tunnel cut becomes of 2.2-2.4 mm width, and then six corneocentezises are carried out consistently. The forward chamber is filled with viscoelastic. The discission aperture is formed by a method of continuous capsulorhexis in diameter of 5.0-5.5 mm in a forward capsule of the lens. The iris retractors are entered into the forward chamber through four corneocentezises, they grasp the edge of the forward capsulorhexis and the edge of the pupil and consistently separate, stretching an iris and a lens capsule. Simultaneously lens bag is suspended and fixed to the iris and the cornea that provides tension weakening of a ciliary zonule and cover of a zone of its dysplasia, and also excludes mobility of a lens during excision of lens masses. Lens masses leave through others two corneocentezises. An elastic intraocular lens Acrysof is implanted in a capsule bag by means of an injector. The capsule bag is longitudinal dissected in the bottom third from two sides on edge of the capsulorhexis to the equator, continuing cuts on a back capsule of a lens on 0.5-0.7 mm from both sides. The bottom haptic lens element stretches and straightens a capsule. The lens is aligned. The viscoelastic is removed and the operation also comes to the end without suture on operational accesses. ^ EFFECT: enlarging the sizes of a capsule bag and possibility of infracapsular implantation of the intraocular lens with conservation of its design. ^ 2 ex |
