SU1524895A1 - Method of extracapsular extraction of cataract on the eyes that suffered vitrectomy - Google Patents

Abstract

This invention relates to ophthalmology. The purpose of the invention is to reduce operative complications. For this, in the method of extracapsular cataract extraction on the eyes after vitrectomy, a corneal incision, anterior capsulotomy, compression of the limb region in the lower segment of the eye, removal of the nucleus and leaching of the lens masses are performed in the flat part of the ciliary body. Through this incision, a spatula is inserted into the vitreous cavity and, simultaneously with the compression of the limbus, pressure is applied to the posterior lens capsule.

The invention relates to medicine, in particular to ophthalmology, and can be used for extracapsular cataract extraction in the eyes of patients undergoing vitrectomy, for example, those suffering from complicated forms of diabetic retinopathy.

The purpose of the invention is to reduce operative complications.

The method is carried out as follows.

Initially, a paracentesis of 0.8-1.0 mm is made through which the tip of the irrigation system is inserted into the cavity of the anterior chamber of the eye, the conjunctiva is cut in mm length parallel to the limbus, then the sclera, the flat part of the ciliary body is punctured shell length 0.8-1.0 mm parallel to the limb 4 mm from the limb along

11h meridian for the right eye and 13 for the left eye. Then a non-penetrating corneous incision 7–9 mm long is made in 2/3 of the corneal thickness 0.5–1 mm from the limbus of the eye, after which a paracentesis is performed for 12 hours, through which micro - cystotic and dissection of the anterior capsule of the lens with simultaneous retraction of the remnants of the anterior capsule to the upper limb of the eye. The remains of the cornea layers in the area of the previously made non-penetrating incision of the cornea of the eye are trimmed, a suture-taping is placed on the central lip of the corneal incision, the remnants of the anterior lens capsule are removed. A spatula is inserted through the incision in the flat part of the ciliary body into the vitreous cavity and is brought under the central

suit the lens of the eye before contact with the posterior lens of the lens. The assistant then lifts the central lip of the corneal incision by suture-holder, after which the surgeon simultaneously exercises a slight pressure on the limb area in the lower segment of the eye block and pressure with a spatula up on the central part of the back surface of the lens, resulting in dislocation of the upper pole of the lens of the eye into the cataract. - thorny wound. Then, the lens core is removed from the cavity of the operated eye, the lens masses are washed out using the aspiration-irrigation method, sutured into the corneal incision and incisions in the flat part of the ciliary body.

The simultaneous impact of a spatula on the back surface of the lens from the bottom up and a slight compression of the eye block in the lower segment preclude the development of severe hypotension of the eye block and greatly facilitate the removal of the lens core in patients.
