A new clinical tool for establishing priorities in scheduling patients for cataract surgery showed both validity and reliability in a study by Swedish researchers.

Mats Lundström, MD, PhD, and colleagues at nine eye clinics adapted the new tool, called NIKE (Nationell Indikations Modell för Katarakt Extraktion), from a similar Canadian instrument. Criteria for setting priorities included bilateral visual acuity, patients' perceived difficulties in daily activities, cataract symptoms, independent living ability and medical/ophthalmic surgical indications, according to the study.

Using NIKE, the researchers grouped 343 cataract patients into four indication levels, with group 1 having the greatest indications for surgery and group 4 having the least. The tool demonstrated good validity; the group with highest indications benefited most from surgery, the researchers said. The instrument also showed high interexaminer reliability, the authors noted.

The study is published in the August issue of Acta Ophthalmologica Scandinavica.
