Abstract Details

Purpose:

To investigate the medical safety, visual results and complication rates in surgery for cataract with primary implantation of a Bag in The Lens IOL in children.

Setting:

Eye Department Sahlgrenska University Hospital Gothenburg, Sweden

Methods:

Medical records of 109 eyes of 84 children who had cataract surgery with primary Bag In the Lens (BIL)-IOL 2009 – 2013 were retrospectively reviewed for systemic or ocular comorbidity, postoperative complications and visual outcome. 42 were male (50%), 40 unilateral and 44 bilateral cataracts. Median age at surgery was 2.5 years (range 2 weeks - 14.1 years). 29 eyes (26.6%) of children were ≤3 months of age and 20 eyes (18.3%) 2 to 4 weeks of age. Median follow-up time was 2.8 years (7 months - 5.8 years). Exclusion criteria were uveitis or ≤6 months of follow-up.

Results:

For the entire cohort, only 5 eyes (4.6%) required treatment for visual axis opacification (VAO). Corrected distance visual acuity (CDVA) at last follow-up was 0.52±0.48 (logMAR; mean±SD) with 50 eyes (48.5%) attaining a CDVA of ≥0.5 (decimal). 15 eyes (13.8%) developed glaucoma. Eyes with systemic or ocular comorbidity by the time of surgery had a higher risk of glaucoma development 57.1% as compared to 3.4% for those without (p<0.0001). Unilateral cataracts were at higher risk of severe visual impairment (CDVA <0.1) rate 3.59 (95% CI 1.11-11.7).

Conclusions:

The BiL-IOL is a safe lens for use in children. It prevents the formation of secondary cataract even in the very young and it is easy to exchange if the growth of the eye differs to what is expected
