 The article presents the results of surgical treatment of 12 patients with pseudophakic and narrowing of capsulorhexis ring that has reduced visual acuity obtained after phacoemulsification with intraocular correction of aphakia to 0.3 and below. Complete occlusion of a capsulotomic opening was observed in 3 patients, dislocation of the intraocular lens with capsular bag ― in 3 patients. Surgical excision of fibrosechanged anterior capsule of the lens within the optical zone ― in 9 patients, and replacement of intracapsular intraocular lens for the anterior chamber intraocular lens ― in 3 patients, helped to improve visual acuity to 0.8-1.0.

Key words: capsular bag fibrosis, stenosis of capsulorhexis ring.
