FIELD: medicine; ophthalmology.
SUBSTANCE: separation of iridocapsular adhesions with a spatula, implantation of the pupillary ring, continuous circular anterior capsulorhexis, phacoemulsification, continuous circular posterior capsulorhexis, partial vitrectomy in the view of the ciliary body by anterior access and IOL implantation are carried out. In this case, the IOL is implanted into the anterior chamber on the anterior surface of the iris, then the first supporting element of the IOL is captured with collet tweezers, pressed against the optical part, the anterior capsule is lifted with a hook, thus opening the capsular bag. After directing the support element to the equator of the bag, the surgeon opens the jaws of the tweezers, and the support element expands in the capsular bag. Then the second support element of the IOL is implanted in the same way. Then, using the “hatchet” manipulator, the optical part is tucked into the capsular bag with rotational movements, a hook is sequentially inserted through paracentesis, the edge of the optical part of the IOL is hooked, and by moving to the centre of the pupil, first from one side, then from the other, it is immersed and infringed in the posterior capsulorhexis. In a particular case, after posterior capsulorhexis, partial vitrectomy and paracentesis hydration, the eye tone is restored with BSS solution to normotonus determined by palpation. In a particular case, a posterior chamber three-part flexible IOL is used which is implanted using collet tweezers, under visual control, by lifting the anterior capsule with a hook, and immersing the supporting elements in the equator of the capsular bag between the sheets of the anterior and posterior capsules.
EFFECT: method allows to simplify the process of IOL implantation during uveal cataract surgery by performing the required sequential actions reducing the risk of possible complications and contributing to the optimal location of the IOL.
