METHOD FOR TREATMENT OF EVERSION OF LOWER EYELID (VERSIONS) Russian patent published in 2025 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: versions of the invention relate to medicine, specifically to ophthalmosurgery, and can be used for treating lower eyelid eversion in involution, in burn injuries of the skin of the face, in the absence of the ability to transplant a skin flap or the patient refuses to transplant, with cicatricial changes. That is ensured by local anaesthesia of the lower eyelid. Two incisions up to 5 mm long are made on the eyelid skin at the edges of the eye socket with a scalpel. That is followed by making two 5-6 mm rhomboid incisions of the conjunctiva under a cartilage at a distance from each other, proportionate to edges of a diameter of a normal cornea with exposing a retractor. Two spiral sutures are applied with using one suture with two needles. First lateral suture is delivered from an outer edge of the eyelid with the first needle pricked in with the lateral suture into a lower point of the rhomboid incision and covering the retractor, and delivering the needle into the upper point of the rhomboid incision with covering a cartilage. Second stick of the needle is made under the first stick in the lower point of the rhomboid incision, and the needle is brought out onto the skin within the preliminary skin incision. Second medial suture needle is used to make a similar suture in parallel to the lateral suture at 1-2 mm from the lateral suture. Second medial suture is applied from an inner edge of the eyelid with repeating the same manipulations. At the skin exit point, the sutures are pulled with placing the lower eyelid correctly. Incision is fixed with knots. Threads are cut. Skin incision is closed with an interrupted suture. Conjunctiva is not sutured. According to the second version of the invention, the suture is applied by means of one syringe needle with two successive spiral sutures. First lateral suture is delivered from an outer edge of the eyelid; a first prick is pricked in with the single-needle suture into an upper point of the rhomboid incision with leaving a free end of suture 50-60 mm long and covering a cartilage. Needle is brought out into the lower point of the rhomboid incision with covering the retractor. Second suture is a medial one; the second needle is pricked in at 1-2 mm from a needle exit in the medial direction, at the level of the needle exit, and the needle is pricked in at the same time into a lower point of the rhomboid incision with covering the retractor. Needle is delivered into an upper point of the rhomboid incision with enclosing the cartilage. Needle is pricked in again under the first prick in from the lower point of the rhomboid incision with the needle brought out onto the skin in the preliminary incision. Then a guide needle is used to enter the skin incision. Passing under musculocutaneous layer. Patient is asked to look upwards or an eye is covered with a protective shield, the needle is brought out in a lower point under a lateral free end of the suture. Whole free end of the suture is immersed into the guide needle and brought out onto the skin. At the skin exit point, the sutures are pulled with placing the lower eyelid correctly; the incision is knotted. Threads are cut. Skin incision is closed with an interrupted suture. Conjunctiva is not sutured.

EFFECT: inventions provide simple and low-impact treatment of eversion of the lower eyelid.
