[Improved technology of simultaneous penetrating keratoplasty and second implantation of posterior chamber intraocular lens in complete or extensive absence of the posterior lenticular capsule].
The authors describe in detail improved technology of simultaneous keratoplasty and second (re)implantation of posterior-chamber disc intraocular lens (IOL) into aphakic and artiphakic eyes (103 operations) in cases with complete or extensive absence of the posterior capsule of the lens. Disc Saturn and TIOL IOLs with circulating supporting elements 7.5 mm in diameter were placed into the posterior chamber using a safe supporting suture and then fixed to the posterior surface of the iris in 2-3 sites. In order to prevent the pupil blocking, basal iridectomies were made in 2-4 sectors; intraoperative bleeding from iridal vessels was arrested by tamponade of the anterior chamber with a hemostatic collagen sponge, and "atonic" mydriasis was removed surgically. A lower incidence of intra- and postoperative complications (injuries to corneal graft endothelium and hemorrhages), reliable fixation of IOL, and good functional results (increase of visual acuity by 0.05-0.8 diopters) attained in 70% patients recommend this single-stage operation for practical ophthalmology.
