Contact Lens Misuse and Sight-Threatening Complications
Since the introduction of daily disposable contact lenses and highly oxygen-permeable silicone hydrogel materials, resulting in improvements in comfort and eye health, contact lens use has skyrocketed. There are at least 125 million contact lens wearers globally, which is increasing by 6% each year. However, despite their generally safe profile, contact lens misuse is a significant and preventable cause of ocular morbidity. Poor hygiene practices, extended wear, and inappropriate storage are all associated with a range of complications that can lead to permanent visual impairment. Common complications include microbial keratitis (MK), corneal hypoxia, and dry eyes, with patient education and prevention key to addressing them.
