Patients Can Reduce Contact Lens Risk: CDC
A Centers for Disease Control (CDC) study shows that 25% of reports to the FDA Medical Device Report (MDR) database on problems with contact lenses involved patient behaviors that could be modified to reduce the risk of eye damage. The report says that during 2005-2015, a total of 1,075 MDRs describing contact lens-related corneal infections were reported to the FDA database. About 20% of the MDRs described a patient who suffered eye damage.
According to the CDC, about 25% of the MDRs described potentially modifiable factors that might have put the patient at risk for a contact lens-related corneal infection such as sleeping in lenses or wearing lenses longer than for the prescribed period. Other studies have shown that sleeping in contact lenses, whether occasionally or as part of a prescribed wearing schedule for extended-wear lenses, increases the risk for contact lens-related eye infections by six-fold to eight-fold, the report says. In addition, 20% of the analyzed MDRs described eye damage after the contact lens-related infection.
“Although contact lenses are a safe and effective form of vision correction if worn and cared for as directed,” the report concludes, “they pose an infection risk to wearers if not worn and cared for properly. Health promotion activities should focus on informing contact lens wearers of common behaviors that might put them at risk for eye infections, such as sleeping in contact lenses and exposing lenses to tap water, distilled water, or recreational water.”
