Researchers Chalmers, Wagner, Mitchell and their associates designed a study to examine age and other risk factors related to infiltrative and inflammatory events (or CIEs) in young contact lenses users. The retrospective, multi-centre study consisted in reviewing 3,549 charts of contact lenses users (aged 8 to 33 during their first fitting visit) and included CIEs from the period of from January 2006 to September2009.
During the review, the scientists took age, gender, lenses and lens care products, and wearing history into account. The charts included 187 CIEs in 159 contact lens users; the highest number of cases cases was recorded in wearers aged 15 to 25 years.
Using a complex statistical model, the researchers reached the conclusion that the age of the patient, the duration of lens wear, the use of lens care products, silicone hydrogel lenses and extended wear had a significant impact on the occurrence of CIEs. However, fitting young patients (8 to 15) led to lower risk of infiltrative events in comparison with other age groups. It is therefore beneficial, the researchers suggest, to fit children who have vision problems with contact lenses.
