New contact lens "can be worn for 22 days"

A new type of contact lens can be worn for 22 days without the wearer suffering from any incidence of microbial keratitis.

The study found that patients wearing Menicon Z rigid gas-permeable contact lenses exhibited no findings of microbial keratitis during the 24-month study, while reported rates of complications were low.

"On the basis of this study, [continuous wear] of the Menicon Z hyper-Dk/t RGP lens provides a safe and full-time vision correction alternative for patients who can adapt to RGP lens wear," the study stated.

During the investigation, subjects were contacted at six-month intervals and experts found that 1,275 of the 1,527 lenses included in the study were worn for 22 days or more.
