Population, Policy and Practice

We are a multi-disciplinary group of researchers with an international reputation for population-level and clinical research that influences public health policy and practice.

Our aim is to promote the health of children and young people and the adults they will become through conducting research:

  • across the life course
  • on common, chronic and complex conditions, in addition to rare disorders
  • on defining and measuring what matters for children, young people and their families
  • recognising the wider contexts of children's lives

Epidemiological study of primary intraocular lens implantation in children under 2 years old with congenital/infantile cataract

IoLunder2 is a binational (UK and Ireland) longitudinal observational study of outcomes following surgery with and without implantation of an artificial intraocular lens (IoL).

Undertaken through the British Isles Congenital Cataract Interest Group (a national research network of consultant ophthalmologists), IoLunder2 has created an internationally unique inception cohort of affected children, enabling us to investigate the risks and benefits of IoL implantation, the key recent innovation in the management of congenital and infantile cataract, which is the most important cause of treatable childhood blindness globally.
