METHOD OF POSTERIOR CHAMBER INTRAOCULAR LENS IMPLANTATION

摘要

FIELD: medicine.;SUBSTANCE: tunnel operative cut is made. Anterior chamber is filled with visco- elastic. Anterior capsulorhexis in form of ellipsis with larger axis 7.0-7.5 mm along tunnel cut and smaller axis 4.0-5.0 mm is made. Crystalline lens masses are removed. Visco-elastic is introduced between leaves of crystalline lens capsule. One support element of intraocular lens (IOL) is introduced into capsule sac as far as opposite equatorial fornix, second support element is introduced into capsule sac by its gradual bending and intraocular lens rotation. Lens centering is performed by rotation until lens support elements are located perpendicularly to capsulorhexis larger axis.;EFFECT: method facilitates removal of crystalline lens masses and intraocular lens implantation, reduces risk of injury of posterior capsule, Zinn tendon fibres with prolapse of vitreous body, trauma of cornea endothelium, prevents development of capsular block, ensures reliable intraocular lens fixation, facilitates performing posterior circular capsulorhexis if necessary.;1 dwg, 2 ex
