Iridovitreal IOL. A 15-year experience of implantation.
The paper reports the results of a 15-year follow-up of implantation of the RSP-3 iridovitreal intraocular lens (IVIOL), designed by the authors. The IOL was implanted to 340 patients after they underwent intracapsular cataract extraction because of lens subluxation as part of eye reconstruction surgery, during secondary implantation and replacement of IOL. IVIOL is implanted in such a way as to achieve its double fixation in the eye, preventing possible dislocation of the IOL to the vitreous: 1) through the adhesion of hydrophilic material of IOL to the posterior surface of the iris and the anterior layers of the vitreous, 2) through mechanical attachment of clip fixation type in the pupillary area. High visual acuity (over 0.6) after IVIOL implantation was achieved in 60 to 75% of cases. Complications of the early and the late (up to 15 years) postoperative periods are rare (5.9%), which is comparable with the results of previous studies of artiphakia with intracapsular fixation. Indications and counterindications for IVIOL implantations in cases of lens capsule defects have been determined. // Russian Ophthalmological Journal, 2011; 4:25-29.
