Contact Lens Problem Risk Factors

Researchers publishing in the eye care journal Investigative Ophthalmology and Visual Science reported results from the Contact Lens Assessment in Youth (CLAY) Study

Regarding the risk factors for corneal infiltrative and inflammatory events in young soft contact lens wearers. Charts from 3549 contact lens patients were examined for the period January 2006 to September 2009 and found to produce 187 corneal infiltrative and inflammatory events (CIEs) in 159 wearers. Age was a significant factor with the most significant risk to those between 15 and 25 years of age. Having a contact lens wearing history of less than one year of soft contact lens (SCL) use was less risky than for longer periods of use. Patients who used multi-purpose care products had 2.86 times more risk of CIE, those wearing silicone hydrogels had 1.85 times more risk of CIE and those wearing their contact lenses on an extended wear basis had 2.37 times greater risk of infiltrates and inflammation from the contacts. The authors concluded “Patient age, years of lens wear, use of multi-purpose care products, silicone hydrogels and extended wear were all significantly associated with CIEs with SCL wear. Use of SCLs in young patients aged 8 to 15 years was associated with lower risk of infiltrative events compared to teens and young adults.”
