FIELD: ophthalmic surgery. SUBSTANCE: invention is designed for surgically treating cataract with soft or small (up to 6 mm) dense nucleus (inborn, half-resolved, traumatic, and non-ripened cataracts) followed by implanting posterior- chamber intraocular lens. First, corneal incision is made and viscous preparation is introduced into anterior chamber. Then, anterior capsule is opened, nucleus and crystalline lens fluid are removed, and intraocular lens is implanted. Opening is performed by horizontal linear incision in the upper equatorial zone, and removal of nucleus and crystalline lens fluid is accomplished using viscous preparation. Lens implant bears diametrically arranged support members. Implant has to be inserted into capsule sac against stop in lower equatorial vault, turned by 5-10 deg., and, under slight pressure, turned through 90 deg. to achieve optical capsulorexis. EFFECT: enabled complete transfer of manipulations from anterior chamber into capsule sac, and created controlled process of removing nucleus and crystalline lens fluid. 2 cl, 3 ex
