PURPOSE

This study evaluated the effectiveness and safety of IOL implantation with transscleral fixation using the knotless Z-suture technique in pediatric patients with congenital lens subluxation.

MATERIAL AND METHODS

The study included 24 children (36 eyes) with grade III congenital subluxation of the lens who underwent phacoaspiration of the subluxated lens with IOL implantation with transscleral fixation using the knotless Z-suture performed in the Kazakh Research Institute of Eye Diseases in Almaty in the period from 2017 to 2021. The average observation period was 31.7±11.3 months (2.0 to 4.5 years). The stability of the IOL position, the state of the intrascleral sutures, visual acuity after surgery, the presence and severity of complications in the long-term period were evaluated.

RESULTS

All patients (100%) had a significant improvement in visual acuity after surgery. No intraoperative complications were registered in any of the cases. Postoperative complications were noted in 8.3% of cases (n=3). The final functional outcome of surgical treatment depended on the presence of concomitant pathology, the main cause of low vision was the development of refractive amblyopia due to refractive errors.

CONCLUSIONS

The presented technique of transscleral fixation of IOL has proven to be reliable, which is especially important for pediatric patients considering their high physical activity and expected lifespan.
