Abstract

Способ имплантации ИОЛ больным с эктопией хрусталика, характеризующийся тем, что после предоперационной регионарной и местной топической анастезии и стандартной обработки операционного поля при проведении операции вначале с помощью ножа-керотома на 9-12 часах выполняют роговичный тоннельный разрез шириной 2,0-2,8 мм, через который офтальмологическим 0,1% раствором трипанового синего окрашивают переднюю капсулу хрусталика и затем вводят вискоэластик, после чего в точке, максимально удаленной от видимой части экватора хрусталика, в зоне от 3 до 9 часов выполняют парацентезное отверстие шириной 0,1-0,2 мм и затем производят круговой капсулорексис в передней капсуле хрусталика диаметром 3,5-6,5 мм, проводят гидродиссекцию и имплантируют внутрикапсульное кольцо (ВКК) с предварительно закрепленной на нем шовной нитью с иглой, после чего последовательно вновь выполняют гидродиссекцию и производят факоэмульсификацию хрусталика, а затем на расстоянии 2,0-3,0 мм от лимба, за парацентезом, иглой-проводником калибра 25-30 G (гейдж) через склеру выполняют прокол, через который извлекают проведенную свободным концом с противоположной стороны через роговичный туннельный разрез, заправленную в проводник иглу с шовной нитью, и производят имплантацию ИОЛ, причем, перекидывая нить от ВКК через один из гаптических элементов ИОЛ и проводя иглу через склеральное отверстие интрасклерально в сторону роговицы так, чтобы игла выходила в ней на 1-3 мм перед лимбом, формируют опорный элемент, за который крепят конструкцию внутрикапсульное кольцо + капсульный мешок + ИОЛ, а затем проводят иглу через тот же роговичный выкол в обратном направлении пA method for implanting an IOL for patients with an ectopic lens, characterized in that after a preoperative regional and local topical anesthesia and standard treatment of the surgical field during the operation, a corneal tunnel incision 2.0-2.8 wide is performed for 9-12 hours first mm, through which the front lens capsule is painted with an ophthalmic 0.1% trypan blue solution and then viscoelastic is injected, after which, at a point as far as possible from the visible part of the lens equator, in the zone from 3 up to 9 hours, perform a paracentesis orifice 0.1-0.2 mm wide and then produce circular capsulorhexis in the anterior capsule of the lens with a diameter of 3.5-6.5 mm, perform hydrodissection and implant an intracapsular ring (IAC) with suture pre-fixed on it with a needle, after which hydrodissection is again performed successively and phacoemulsification of the lens is carried out, and then at a distance of 2.0-3.0 mm from the limb, for paracentesis, a 25-30 G gauge needle (gage), a puncture is performed through the sclera, through which remove conducted the free end from the opposite side through the corneal tunnel incision, a needle with suture thread inserted into the conductor, and IOLs are implanted, moreover, throwing the thread from the IAC through one of the haptic elements of the IOL and passing the needle through the scleral hole intrasclerally to the cornea so that the needle left in it 1-3 mm in front of the limb, form a support element, behind which the structure of the capsule ring + capsule bag + IOL is fixed, and then the needle is passed through the same corneal puncture in the opposite direction

Claims

A method for implanting an IOL for patients with an ectopic lens, characterized in that after a preoperative regional and local topical anesthesia and standard treatment of the surgical field during the operation, a corneal tunnel incision 2.0-2.8 wide is performed for 9-12 hours first mm, through which the front lens capsule is painted with an ophthalmic 0.1% trypan blue solution and then viscoelastic is injected, after which, at a point as far as possible from the visible part of the lens equator, in the zone from 3 up to 9 hours, perform a paracentesis orifice 0.1-0.2 mm wide and then produce circular capsulorhexis in the anterior capsule of the lens with a diameter of 3.5-6.5 mm, perform hydrodissection and implant an intracapsular ring (IAC) with suture pre-fixed on it with a needle, after which hydrodissection is again performed successively and phacoemulsification of the lens is carried out, and then at a distance of 2.0-3.0 mm from the limb, for paracentesis, a 25-30 G gauge needle (gage), a puncture is performed through the sclera, through which remove conducted the free end from the opposite side through the corneal tunnel incision, a needle with suture thread inserted into the conductor, and IOLs are implanted, moreover, throwing the thread from the IAC through one of the haptic elements of the IOL and passing the needle through the scleral hole intrasclerally to the cornea so that the needle left in it 1-3 mm in front of the limb, form a support element, behind which the structure of the capsule ring + capsule bag + IOL is fixed, and then the needle is passed through the same corneal puncture in the opposite direction At an angle from the previous corneal passage, it is removed from paracentesis, after which, using the appropriate pulling, the threads are centered on the IOL, then a knot is tied onto the threads and immersed in the stroma of the cornea in paracentesis, viscoelastic is removed from the anterior chamber, capsular bag and from under the lens , corneal stroma is sealed by dosed hydration and glucocorticoid preparation and antibiotic solution are administered subconjunctively.
