Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Congenital subluxation of the lens as a complication of Marfan syndrome, Weill-Marchesani syndrome, microspherophakia, etc. leads to the development of amblyopia and requires timely surgical treatment with removal of the subluxated lens and implantation of an artificial intraocular lens (IOL). IOL implantation in children with pathology of the ligamentous apparatus of the lens remains an urgent problem of ophthalmic surgery due to the lack of a consensus regarding the IOL fixation method among practitioners. 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: =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.
