This was a first\u2010experience cohort of an experienced paediatric cataract surgeon with this type of lens.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Nine infants (13 eyes) with a median age at surgery of 28\u2009days (range, 21\u201349\u2009days) were included. The median follow\u2010up time was 21.6\u00a0months (range, 12.2\u201323.4\u00a0months). The lens was correctly implanted with the anterior and posterior capsulorhexis edges placed into the interhaptic groove of the BIL IOL in seven of 13 eyes; none of these eyes developed VAO. In the remaining six eyes, the IOL was only fixated to the anterior capsulorhexis edge, and in these cases, an anatomical anomaly of the posterior capsule and\/or anterior vitreolenticular interface dysgenesis were observed. These six eyes developed VAO. One eye had a partial iris capture in the early postoperative phase. Otherwise, the IOL remained well centred and stable in all eyes. Anterior vitrectomy was necessary in seven eyes due to vitreous prolapse. One patient with unilateral cataract was diagnosed with bilateral primary congenital glaucoma at 4\u00a0months of age.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Implantation of the BIL IOL is safe even in the youngest age group less than 12\u2009weeks of age. Although being a first\u2010experience cohort, the BIL technique is shown to reduce the risk of VAO and the number of surgical procedures.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aos.15647","type":"journal-article","created":{"date-parts":[[2023,2,18]],"date-time":"2023-02-18T17:51:26Z","timestamp":1676742686000},"page":"636-643","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Bag\u2010in\u2010the\u2010lens
