Description

Invenţia se referă la medicină, în special la oftalmologie. The invention relates to medicine, in particular to ophthalmology.

Este cunoscut dispozitivul pentru tratamentul cataractei senile, care include o seringă cu ac executat din două segmente, unul proximal cu lungimea de 9 mm este îndoit sub un unghi de 135° faţă de axa longitudinală a seringii, iar unul distal cu lungimea de 3 mm este perpendicular pe axa menţionată, totodată metoda de tratament al cataractei senile constă în aceea că se efectuează o incizie la nivelul limbului, se deschide camera anterioară şi se introduce aer steril cu ajutorul dispozitivului menţionat mai sus, apoi cu vârful acului dispozitivului se efectuează capsulotomia anterioară circulară, se introduc 0,3 ml de aer steril sub capsula restantă a cristalinului şi cu vârful acului dispozitivului se divizează nucleul în două fragmente, după care se implantează cristalinul artificial [1]. A device for the treatment of senile cataract is known, which includes a syringe with a needle made of two segments, a proximal one with a length of 9 mm is bent at an angle of 135° to the longitudinal axis of the syringe, and a distal one with a length of 3 mm is perpendicular to the said axis, at the same time the method of treatment of senile cataract consists in making an incision at the limbus level, opening the anterior chamber and introducing sterile air using the device mentioned above, then with the tip of the device's needle a circular anterior capsulotomy is performed, 0.3 ml of sterile air is introduced under the remaining capsule of the lens and with the tip of the device's needle the nucleus is divided into two fragments, after which the artificial lens is implanted [1].

Dezavantajul dispozitivului cunoscut constă în imposibilitatea mobilizării nucleului cristalinului, în cazul când acesta este fixat de capsula posterioară, fapt ce poate duce la pierdere de corp vitros în timpul intervenţiei, contribuind la declanşarea unui glaucom secundar sau la o iridociclită în perioada postoperatorie, totodată utilizarea acestui dispozitiv exercită presiuni asupra structurilor intraoculare. The disadvantage of the known device is the impossibility of mobilizing the lens nucleus, if it is fixed by the posterior capsule, which can lead to loss of vitreous body during the intervention, contributing to the triggering of secondary glaucoma or iridocyclitis in the postoperative period, while the use of this device exerts pressure on the intraocular structures.

Problema pe care o rezolvă invenţia propusă constă în implantarea cristalinului artificial de cameră posterioară prin camera anterioară. The problem solved by the proposed invention consists in implanting the posterior chamber artificial lens through the anterior chamber.

Conform invenţiei, dispozitivul pentru tratamentul cataractei senile hipermature include o seringă cu ac bont, îndoit sub un unghi de 135° faţă de axa longitudinală a seringii, lungimea acului fiind de 10 mm. According to the invention, the device for the treatment of hypermature senile cataract includes a syringe with a blunt needle, bent at an angle of 135° to the longitudinal axis of the syringe, the needle length being 10 mm.

Metoda de tratament al cataractei senile hipermature constă în aceea că se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se efectuează o incizie a conjunctivei la nivelul limbului, ce corespunde orelor 10°°…14°° şi a corneei ce corespunde orelor 11°°…13°°, se deschide camera anterioară şi se efectuează capsulorexusul anterior la nivelul orei 11°°, cu ajutorul dispozitivului conform invenţiei se mobilizează nucleul, după care el se fixează şi se înlătură prin mişcări de rotaţie în direcţia acelor de ceasornic, apoi se implantează cristalinul artificial, se suturează corneea şi conjunctiva, iar în spaţiul subconjunctival se introduce un antibiotic şi un remediu steroid. The method of treatment of hypermature senile cataract consists in performing local and regional anesthesia, fixing the superior rectus muscle, making an incision of the conjunctiva at the level of the limbus, corresponding to 10°°…14°° and of the cornea corresponding to 11°°…13°°, opening the anterior chamber and performing the anterior capsulorexus at the level of 11°°, using the device according to the invention, the nucleus is mobilized, after which it is fixed and removed by rotational movements in a clockwise direction, then the artificial lens is implanted, the cornea and conjunctiva are sutured, and an antibiotic and a steroid remedy are introduced into the subconjunctival space.

Rezultatul constă în simplitatea intervenţiei chirurgicale de extracţie a nucleului cristalin, ceea ce permite efectuarea unei incizii mai mici a limbului. The result is the simplicity of the surgical intervention to extract the crystalline nucleus, which allows for a smaller incision in the limbus.

Dispozitivul pentru tratamentul cataractei senile hipermature este simplu în executare şi constă dintr-o seringă cu ac bont, îndoit sub un unghi de 135° faţă de axa longitudinală a seringii, lungimea acului fiind de 10 mm. The device for the treatment of hypermature senile cataract is simple in execution and consists of a syringe with a blunt needle, bent at an angle of 135° to the longitudinal axis of the syringe, the needle length being 10 mm.

Metoda revendicată la fel este simplă în efectuare şi nu este costisitoare. Metoda de tratament al cataractei senile se realizează în modul următor: se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se efectuează o incizie a conjunctivei la nivelul limbului, ce corespunde orelor 10°°…14°° şi a corneei ce corespunde orelor 11°°…13°°, se deschide camera anterioară şi se efectuează capsulorexusul anterior la nivelul orei 11°°. Cu ajutorul dispozitivului conform invenţiei se mobilizează nucleul, după care el se fixează şi se înlătură prin mişcări de rotaţie în direcţia acelor de ceasornic, apoi se implantează cristalinul artificial, se suturează corneea şi conjunctiva, iar în spaţiul subconjunctival se introduce un antibiotic şi un remediu steroid. The claimed method is also simple to perform and inexpensive. The method of treating senile cataract is performed in the following way: local and regional anesthesia is performed, the superior rectus muscle is fixed, an incision is made in the conjunctiva at the level of the limbus, corresponding to 10°°…14°° and in the cornea corresponding to 11°°…13°°, the anterior chamber is opened and the anterior capsulorexus is performed at the level of 11°°. With the help of the device according to the invention, the nucleus is mobilized, after which it is fixed and removed by rotational movements in the clockwise direction, then the artificial lens is implanted, the cornea and conjunctiva are sutured, and an antibiotic and a steroid remedy are introduced into the subconjunctival space.
