[The status of the iridocorneal angle after the implantation of anterior chamber intraocular lenses with flexible supporting elements].

The study was undertaken to examine the status of the iridocorneal angle (ICA) 1 to 4 years after implantation of anterior chamber intraocular lens with flexible supporting devices designed by M. L. Dvali. Correct implantation and gonioscopic monitoring wherein were found to provide reliable lens fixation, as a rule, in the area of the scleral spur and, occasionally, to the anterior part of the ciliary body, if the latter was broad. Additional fixation of the supporting devices was attained by delicate commissures at their small extent at the sites of iris contact, which were detected in the majority of cases. Strangulation of the iris or fixation in its periapical part occurred in small cases and were observed in the upper portion of ICA. Corneal epithelial contact with the supporting devices was revealed in 5.4% of cases, as well as in the upper part of ICA. Only in 1 out of 37 cases, the changes in the drainage area such as iris strangulation at a great extent were sufficient to impair its function and required additional surgical correction. The remaining eyes showed no abnormal intraocular fluid circulation. The visual acuity in 35 eyes was as great as 0.5 or more.
