Replacing lenses at night doesn't lower the risk of complications for people using 30-day extended-wear/continuous-wear (EW/CW) contact lenses when compared to changing lenses monthly, suggests a study – "The Effect of Daily Lens Replacement During Overnight Wear on Ocular Adverse Events", appearing in the December issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part ofWolters Kluwer Health.
In contrast, replacing lenses every morning reduces the overall rate of "ocular adverse events," reports the study by Jerome Ozkan, BOptom of Brien Holden Vision Institute, Sydney, and colleagues. The researchers write, "Contact lens wearers on an EW/CW schedule should be advised to minimize lens handling prior to sleep to reduce the risk of complications."
