SU1500297A1 - Method of implantation of artificial lens - Google Patents

Abstract

This invention relates to ophthalmology. To reduce the morbidity of the operation, operative and postoperative complications, by ensuring that the haptic element of the artificial lens is introduced into the upper capsule pocket of the prepared lens bag, iridocapsuloretraction is performed with a single-stage iris retractor of the pupillary edge of the iris and the anterior capsule edge of the upper capsule pocket. The artificial lens is shifted towards the lower capsular pocket, and the non-implanted haptic element is brought under the iris retractor and tucked into the upper capsule pocket. To visually monitor the position of the haptic element in the upper capsule pocket, its front capsule is exposed by stretching the pupil upward and drying the edge of its discharge.

Description

This invention relates to medicine, in particular, eye microsurgery and implantology.

The purpose of the invention is to reduce the morbidity of the operation, operating, postoperative complications and visual control over the position of the haptic element in the upper capsule pocket.

The method is carried out as follows.

After achieving medical mydriasis, anesthesia and opening the anterior chamber of the eye with the incision of the cornea along the limb, incision of the anterior capsule along the 9 ° - 2 chord, removal of the core, intracapsular microsurgery and capsule-cleaning, the artificial crystalline lens is inserted into the lower capsule pocket with an element . The unimplanted, arcuate opposite element is slightly lifted with tweezers and an iris retractor is held under it. Iriocapsuloretraction with an iris retractor with simultaneous capture of the pupillary edge of the iris and edge of the anterior capulum of the upper capsular pocket, while the artificial lens is slightly shifted towards the lower capsular pocket by gripping the tweezers behind an un-implanted haptic element, brings it under. and tucked into the upper capsule pocket.

Visual control of the position in the upper capsule pocket of the haptic element is performed after exposing the anterior capsule by stretching with pupil tweezers.

upwards, exposing the upper edge of the incision of the anterior capsule and its drying.

example. Patient M., 50 years old, was admitted to the surgical department on 08/27/87 with a diagnosis of a cataract in both eyes. Visual acuity of the right eye 0.1 s - su1 1.0 ah .120 0.2. Visual acuity of the left eye 0.1 s - 1.75 0.2.

08.28.87, an extracapsular cataract extraction with simultaneous intracapsular implantation and fixation of an artificial lens was performed on the right eye.

After treatment of the operative field, retrobulbar anesthesia, akinesia, and immobilization of the eye block were performed by applying a bridle suture on the superior straight muscle. The eye slit was opened with a blepharostat. A puncture was made at the limbus for 10 hours. Through it, an injection cannula with a curved tip was inserted into the anterior chamber, with the help of which the anterior capsule was cut along the chord - 2. Then the cornea was cut through the limb and the extraction was performed dre with. near soft soft masses. On the corneal incision, 2 supramid sutures were applied, intracapsular microsurgeons and capsulumulation were performed. After removing the supramid sutures, a support element and an artificial lens are inserted into the anterior chamber under the edge of the anterior capsule of the lower capsule pocket. Then, with tweezers, they captured the arc of the upper element, lifted the iris retractor a little and under it, which simultaneously captured the pupillary edge of the iris and the edge of the anterior capsule of the upper capsular pocket and made iridocapsulometry. At the same time, with a pair of tweezers, the lens was somewhat shifted towards the lower capsular pocket and the arcuate element was brought under the iris retractor. The visual control over the position of the haptic element in the upper capsule pocket was carried out by stretching the pupil upwards, exposing the upper edge of the incision of the anterior capsule and drying it.

In order to reduce injuries. the operation of the basal iridektori (iri-: dotomy) was not performed. Front

the capsule of the lower capsular pocket in the region of the pupil is removed.

On a corneal incision 7 nodal supramid sutures are imposed. Antibiotics and corticosteroids were administered prophylactically under the conjunctiva, inhibitors of prostaglandins synthesis (indomethacin) and antihistamines (suprastin) were prescribed inside, intramuscularly injections of hetamycin were administered. A sterile dressing is applied to the operating eye.

The postoperative period was uneventful.

When viewed on August 28, 2007, the right eye did not have a detachable one, the conjunctival hyperemia was small, the sutures were clean, there was little descent in the upper quarter of the cornea. The front camera is deeper than average, the moisture is transparent, the iris is calm, the pupil is round in the center, its reaction to light is alive. There is no effusion of fibrin in the anterior chamber. Linz is clean, centered with pupil. The back capsule is transparent. The fundus of the eye, the optic nerve head is not changed, the boundaries are clear in the macular area and at the periphery of the fundus of the eye are not marked, the retinal vessels are not. changed. Intraocular pressure in the norm (palpation). Locally in the right eye, drops of sofradex 3 times a day are prescribed.

At discharge 03.09.87, the right eye is calm, the seams are clean, the cornea is transparent, the anterior chamber is of medium depth, and the moisture is transparent. The iris is calm. The pupil is round, in the center. The position of the artificial lens in the lens bag is stable, there is no iridodonese. The lens is clean, centered with pupil. The back capsule is transparent. The fundus of the eye without visible pathology. The intraocular pressure is 19 mmHg. (according to Maklakov).

The visual acuity of the right eye is 0.7 s — su1 l, 0 ah 165 ° 1.0.

The condition of the left eye, as in the admission.

On repeated examinations of October 11, 1987: the right eye is calm, the stitches are removed from the cornea. Optical media are transparent. The pupil is round. The position of the artificial lens is stable, the lens of the lens is centered with the pupil. The fundus is normal.

The right eye is calm, the cornea is transparent, the pupil is round in the center, the reaction to the light is alive. The lens of the artificial lens is centered with the pupil, its position is stable (no pseudo-facodontics), the posterior capsule is transparent. The fundus of the eye without visible pathology. The acuity of vision is 0.8 s - cy1 1, ah 125 1.0.

In comparison with the known, the proposed method of implantation of an artificial lens reduces traumatic surgery, operative and postoperative complications due to the guaranteed introduction of a haptic element into the upper capsule pocket.
