Precaution while using Contact Lenses
What went wrong
The FDA has received several reports of corneal ulcers, keratitis, and other eye infections associated with using daily disposable contact lenses for longer than the period recommended. Ophthalmologists and other eye care professionals believe the reported problems are caused by contact lens wearers poor hygiene and failure to follow directions when using and caring for these types of lenses. Reports of consumers wearing daily disposable contact lenses for 6 or 7 days instead of 1 day are of particular concern. Eye problems, including corneal ulcers, can develop rapidly and lead to loss of vision. Patients with eye infections secondary to contact lens wear may require treatment with antibiotics. Some infections have led to serious injuries such as corneal ulcers that required corneal transplants.
