Dislocation of the intraocular lens (IOL) is a serious complication in cataract surgery. Therefore, the search for an effective method of IOL fixation for non-standard surgical situations is still important. Purpose. To analyze clinical results of flanged corneoscleral IOL fixation the technique using polytetrafluoroethylene sutures. Material and methods. The results of surgical treatment of 34 patients (34 eyes) who underwent IOL suturing with suture material made of polytetrafluoroethylene 6-0 (Ecoflon) through the sclera and fixation of flanges in the lumen of corneal paracentesis (Sclerocorneal IOL Fixation Technique) without incisions of the conjunctiva and sclera were analyzed. Results. The average index of maximally corrected visual acuity before surgery was 0.27±0.11. A day after surgery, this parameter increased to 0.41±0.1. One week after surgery, the average index of maximally corrected visual acuity was 0.65±0.1, while the improvement in visual acuity was statistically significantly different from the parameter before surgery and a day after surgery (p<0.05). Conclusion. Application of polytetrafluoroethylene suture material in the ab externo technique, passing through the sclera and fixing the flanges in the lumen of the corneal paracentesis is safe and effective method. As a result, patients had positive visual acuity dynamics with a low frequency of complications.
