Description

Invenţia se referă la medicină, în special la oftalmologie şi poate fi aplicată pentru tratamentul cataractei senile. The invention relates to medicine, in particular to ophthalmology and can be applied for the treatment of senile cataract.

Este cunoscută metoda de tratament al cataractei senile, care constă în aceea că se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se detaşează conjunctiva de la limb, se incizează conjunctiva la nivelul limbului, care corespunde orelor 10°°-14°°, se incizează corneea la nivelul orelor 10°° până la 14°°, se marchează capsula anterioară, se lărgeşte incizia corneei spre nivelul orelor 10°° şi 14°°, se efectuează capsulorexisul anterior prin extracţia cataractei senile cu aplicarea unui implant de cristalin artificial de camera posterioară, apoi se suturează conjunctiva, se aplică un antibiotic şi un preparat corticosteroid, se eliberează muşchiul rect superior şi se aplică un pansament monocular aseptic [1]. The method of treating senile cataract is known, which consists of performing local and regional anesthesia, fixing the superior rectus muscle, detaching the conjunctiva from the limbus, incising the conjunctiva at the level of the limbus, which corresponds to 10°°-14°°, incising the cornea at the level of 10°° to 14°°, marking the anterior capsule, widening the corneal incision towards the level of 10°° and 14°°, performing anterior capsulorhexis by extracting the senile cataract with the application of an artificial lens implant in the posterior chamber, then suturing the conjunctiva, applying an antibiotic and a corticosteroid preparation, releasing the superior rectus muscle and applying an aseptic monocular dressing [1].

Dezavantajele acestei metode constau în imposibilitatea efectuării unui capsulorexis circular perfect dozat, din care cauză deseori capsula anterioară se rupe spre ecuatorul cristalinului sau chiar şi spre capsula posterioară, determinând astfel o rupere a ligamentului Zinn. Acest fapt în cele din urmă determină o decentrare a cristalinului artificial implantat ce poate declanşa un glaucom secundar, o uveită postoperatorie, o keratopatie edematobuloasă sau o detaşare de retină. The disadvantages of this method are the impossibility of performing a perfectly dosed circular capsulorhexis, which often causes the anterior capsule to tear towards the lens equator or even towards the posterior capsule, thus causing a rupture of the Zinn ligament. This ultimately causes a decentering of the implanted artificial lens which can trigger secondary glaucoma, postoperative uveitis, edematobullous keratopathy or retinal detachment.

Problema pe care o rezolvă invenţia propusă constă în obţinerea unei stabilităţi a cristalinului artificial implantat. The problem solved by the proposed invention consists in obtaining stability of the implanted artificial lens.

Conform invenţiei, metoda de tratament al cataractei senile constă în aceea că se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se incizează conjunctiva la nivelul limbului, se incizează corneea, se marchează capsula anterioară, se efectuează o incizie triunghiulară a capsulei anterioare la nivelul orei 18°° cu lungimea laturilor de 3 mm, apoi cu ajutorul unei seringi cu acul îndoit sub un unghi de 135° în capsula anterioară, circular, pe un diametru de 5…6 mm, se efectuează microperforaţii cu o distanţă de 2…3 mm între ele, după care se excizează porţiunea circulară menţionată cu diametrul de 5…6 mm şi nucleul cristalinului, se efectuează lavajul maselor cristaliniene, se efectuează două iridotomii ce corespund orelor 11°° şi 13°°, se implantează cristalinul artificial de camera posterioară, după care se suturează corneea, se reface camera anterioară prin introducere de ser fiziologic steril, se suturează conjunctiva, în spaţiul subconjunctival se introduce un antibiotic şi un remediu corticosteroid şi se eliberează muşchiul rect superior. According to the invention, the method of treating senile cataract consists in performing local and regional anesthesia, fixing the superior rectus muscle, incising the conjunctiva at the limbus level, incising the cornea, marking the anterior capsule, making a triangular incision of the anterior capsule at the 18°° o'clock level with a side length of 3 mm, then using a syringe with a needle bent at an angle of 135° in the anterior capsule, circularly, over a diameter of 5…6 mm, microperforations are made with a distance of 2…3 mm between them, after which the mentioned circular portion with a diameter of 5…6 mm and the nucleus of the lens are excised, the lens masses are washed, two iridotomy are performed corresponding to the 11°° and 13°° o'clock positions, the artificial lens is implanted in the posterior chamber, after which the cornea is sutured, the anterior chamber is restored by introducing sterile physiological serum, the sutures are conjunctiva, an antibiotic and a corticosteroid remedy are introduced into the subconjunctival space and the superior rectus muscle is released.

Rezultatul constă în simplificarea intervenţiei microchirurgicale cu minimalizarea complicaţiilor intra - şi postoperatorii. The result is the simplification of microsurgical intervention with the minimization of intra- and postoperative complications.

Metoda de tratament al cataractei senile se realizează în modul următor: se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se incizează conjunctiva la nivelul limbului, se incizează corneea, se marchează capsula anterioară, se efectuează o incizie triunghiulară a capsulei anterioare la nivelul orei 18°° cu lungimea laturilor de 3 mm, apoi cu ajutorul unei seringi cu acul îndoit sub un unghi de 135° în capsula anterioară, circular, pe un diametru de 5…6 mm, se efectuează microperforaţii cu o distanţă de 2…3 mm între ele, după care se excizează porţiunea circulară menţionată cu diametrul de 5…6 mm şi nucleul cristalinului, se efectuează lavajul maselor cristaliniene, se efectuează două iridotomii ce corespund orelor 11°° şi 13°°, se implantează cristalinul artificial de camera posterioară, după care se suturează corneea, se reface camera anterioară prin introducere de ser fiziologic steril, se suturează conjunctiva, în spaţiul subconjunctival se introduce un antibiotic şi un remediu corticosteroid şi se eliberează muşchiul rect superior. The method of treatment of senile cataract is performed in the following way: local and regional anesthesia is performed, the superior rectus muscle is fixed, the conjunctiva is incised at the limbus level, the cornea is incised, the anterior capsule is marked, a triangular incision of the anterior capsule is performed at the 18°° level with the length of the sides of 3 mm, then using a syringe with a needle bent at an angle of 135° in the anterior capsule, circularly, on a diameter of 5…6 mm, microperforations are performed with a distance of 2…3 mm between them, after which the mentioned circular portion with a diameter of 5…6 mm and the nucleus of the lens are excised, the lens masses are lavaged, two iridotomy are performed corresponding to the 11°° and 13°° hours, the artificial lens is implanted in the posterior chamber, after which the cornea is sutured, the anterior chamber is restored by introducing sterile physiological serum, the conjunctiva is sutured, An antibiotic and a corticosteroid remedy are introduced into the subconjunctival space and the superior rectus muscle is released.
