Aim. To describe the technique and to assess the results of phacoemulsification in eyes with extensive zonular defects of Zinn ligament fibers.Methods. Phacoemulsification was performed through a 2.2- mm corneal tunnel incision on adhesive viscoelastic bed. The lens was stabilized with a capsular tension ring. The operation was finished with intraocular implantation and its suturing to the iris. The study included 36 patients [42 eyes, 23 males (63.9%), 13 females (36.1%)] in whom phacoemulsification has been performed. Visual acuity before surgery ranged from 0.01 to 0.7 (mean 0.2±0.18). Intraocular pressure ranged from 15 to 25 mm Hg (mean 19.2±4.5 mm Hg). Corneal astigmatism value before surgery ranged from 0 to 2.25 D (mean 0.87±0.63 D).Results. Postoperatively the following complications were observed: an inflammatory reaction in 3 eyes (7.1%), inflammation of Descemet’s membrane in 3 (7.1%) cases, ocular hypertension in 9 (21.4%) eyes. All the complications were drug treated within 3-5 days. On the second day mean visual acuity was assessed as 0.56±0.12,1 month after surgery - 0.70±0.16,6 months after surgery - 0.75±0.21, and 1 year after surgery - 0.74±0.19. Corneal induced astigmatism 1 year after the surgery ranged from 0.0 to 1.5 D (mean 0.39±0.16 D).Conclusion. The presented technology of phacoemulsification is relatively safe, effective and provides a possibility to rehabilitate patients with cataract combined with extensive zonular defects of Zinn ligament fibers in minimal terms.
