摘要
FIELD: medicine.;SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used in an intraocular lens (IOL) implantation into the patients suffering from ectopia lentis. That is ensured by making a corneal tunnel incision with a keratome at 9-12 o'clock. An anterior capsule of the lens is stained through this incision, and a viscoelastic is introduced. A paracentesis is made in a point remote as much as possible from the visible portion of an equator of the lens within the range of 3 to 9 o'clock. A circular capsulorhexis is performed in the anterior capsule of the lens. Hydrodissection is performed. An intracapsular ring (ICR) is implanted. A retention needle suture is pre-fixed therein. Another hydrodissection is performed again. Phacoemulsification of the lens is performed. A guide needle is used to puncture the sclera at 2.0-3.0 mm from the limb behind the paracentesis. That is followed by removing the guide needle with the suture with its free end delivered from the opposite side through the corneal tunnel incision. The IOL is implanted. The suture is thrown over from the ICR through one of the haptic elements of the IOL. The needle is delivered through the scleral opening inside the sclera towards the cornea so that the needle is brought out at 1-3 mm in front of the limb. A support element is formed with the intracapsular ring + capsular sac + IOL structure attached behind it. The needle is delivered through the same puncture in the same direction at an angle from the previous corneal pass. It is brought out from the paracentesis. The IOL is aligned with respective suture tightening. The suture is knotted and immersed into the corneal stroma in the paracentesis. The viscoelastic is removed from the anterior chamber, the capsular sac and from under the lens. The corneal stromas are sealed by graduated hydration. A glucocorticoid preparation and an antibiotic solution are administered subconjunctivally.;EFFECT: method enables relieving Marfan's symptom with a minimum effect on the vitreous body and eliminates a necessity of the following surgical management.;3 ex
