Transscleral Fixation Of An Intraocular Lens Using The Z-Shaped Suture In The Surgical Treatment Of Lens Subluxation In Children

Evaluation of the efficacy and safety of IOL implantation with transscleral fixation using the knotless Z - suture method in pediatric patients with congenital lens subluxation.

The study included 24 children (36 eyes) with congenital lens subluxation, who underwent phacoaspiration of the subluxated lens with IOL implantation with transscleral fixation using a knot-free Z-shaped suture at the Kazakh Eye Research Institute, Almaty, from 2017 to 2021.

The mean follow-up period was 31.7±11.3 months (from 2 to 4.5 years). The stability of the position of the intraocular lens, the consistency of intrascleral sutures, visual acuity after surgery, the presence and severity of complications in the long-term period were assessed.

After the surgery, there was a significant improvement in visual acuity in all patients. Intraoperative complications were not observed in any case. Postoperative complications were noted in 8.3% of cases (n=3); no reoperation was required in any case. The final functional result of surgical treatment depended on the presence of concomitant pathology; the main causes of reduced vision were refractive errors and the development of refractive amblyopia.

The presented Z - suture method of transscleral fixation of IOLs provides reliable fixation, which is especially important for pediatric patients, given the high physical activity of patients and the expected life expectancy.
