The utility model provides a lens capsular bag anchoring device. The lens capsular bag anchoring device comprises an anchoring body and an anchoring arm. The anchoring body is in an M shape, the two anchoring arms are connected to the two opposite ends of the anchoring body respectively, and fixing rings are arranged at the ends, away from the anchoring body, of the anchoring arms. In the operation process, a suture is used for knotting at the V-shaped tip end of the anchoring body, and the other end of the suture penetrates out of the sclera of the ciliary sulcus and is knotted outside the eye to be fixed between sclera layers. The middle V-shaped portion of the anchoring body is arranged in front of an anterior capsule, the two protrusions at the upper end of the M shape pull the edge of an anterior capsule ring, the anchoring arm is implanted into a capsule bag, the equator of the capsule bag is jacked, pressed and pulled, the crystal capsule bag is made to restore the shape, and when an operation is finished, the anchoring arm can be permanently fixed to the sclera, and the IOL and the capsule bag are prevented from deviating together. Secondly, for a patient with dislocation of the IOL-capsular complex, the IOL-capsular complex can be pulled to the normal position through the anchoring device and fixed to the sclera.

FIELD: medicine; ophthalmology.SUBSTANCE: after performing phacoemulsification, linear incisions are made in the anterior capsule from the edge of the capsulorhexis to the vault of the capsular bag in opposite meridians, forming a 1 mm wide flap. Next, the flap is removed and pinched in the previously formed coloboma of the iris. In a particular case, if necessary, the flap is additionally pinched in the paracentesis, after which the paracentesis is sutured.EFFECT: reliable fixation, a sufficient level of tension and anatomically correct position of the IOL, and preventing its rotation, ensuring the absence of refractive shift.2 cl, 10 dwg, 2 ex

A capsulorhexis device is inserted into an incision site of a cornea to make an incision in an anterior capsule surrounding a crystalline lens. The capsulorhexis device includes a loop having elasticity and conductivity; a moving member having one end fixed and coupled to the loop; an insertion guide configured so that, while the incision is being made in the crystalline lens capsule, a front end thereof is inserted into the incision site of the cornea; and a housing having one end coupled to a rear end of the insertion guide, wherein the loop is housed in the housing and, to make the incision in the crystalline lens capsule, slides in the housing together with the moving member to pass through the insertion guide and be deployed into an anterior chamber of the eye.

The application discloses a posterior chamber type artificial lens with a lens and a method for improving stability and communication capacity of the artificial lens. The artificial lens comprises an optical area and a supporting part, the supporting part is arranged outside the optical area, and a circular central hole is arranged in the center of the optical area; the supporting part comprises a closed haptic and haptic feet arranged outside the closed haptic, a haptic hole is arranged on one side of the closed haptic close to the optical area, an elliptical water guide hole is arranged on the closed haptic close to the haptic feet, the haptic feet are four in number, and positioning holes are arranged on the haptic feet. The elliptical water guide hole close to the haptic feet of the artificial lens can disperse pressure, reduce axial displacement of the artificial lens, keep the position relatively constant, and has high stability; the artificial lens has good communication capacity, the elliptical water guide hole is arranged between an iris and a lens anterior capsule, can make aqueous humor communicate smoothly, reduce contact with the iris and the anterior capsule, and reduce deposition of pigments on the surface of the artificial lens and in the chamber angle. The artificial lens can effectively prevent cataract, pupil block or angle closure glaucoma and the like.
