Extended wear contact lenses.

The experience with the complications associated with extended wear contact lenses has made practitioners and patients fearful of this modality. Today, strong scientific evidence suggest that the hypoxia problems associated with extended wear lenses have been solved. Good clinical evidence suggests that the new high-Dk silicone lenses are safe and can be worn successfully for up to 30 days. Patients can now be offered contact lenses that meet their desire of continuous vision; however, practitioners and patients must be instructed regarding the signs and symptoms of contact lens complications. Practitioners need to be educated in the diagnosis and management of the complications. Patients need to be educated about the need for proper eye care, contact lens care regimens, and appropriate follow-up visits.
