Summary
New high-Dk silicone contact lenses offer safe, extended wear for up to 30 days, resolving previous hypoxia issues. Patient and practitioner education on complication management and proper eye care is crucial for successful continuous vision.
Area of Science:
- Ophthalmology
- Corneal Physiology
- Contact Lens Technology
Background:
- Extended wear contact lenses were previously associated with complications, leading to patient and practitioner apprehension.
- Hypoxia was a primary concern with older extended wear lens materials.
Purpose of the Study:
- To evaluate the safety and efficacy of new high-Dk silicone contact lenses for extended wear.
- To inform practitioners and patients about the potential for safe 30-day continuous wear.
- To emphasize the importance of education regarding contact lens complications.
Main Methods:
- Review of clinical evidence and scientific data on high-Dk silicone lenses.
- Assessment of safety and complication rates associated with 30-day wear.
- Analysis of patient and practitioner educational needs.
Main Results:
- Strong scientific evidence indicates that hypoxia issues with extended wear lenses have been resolved.
- Good clinical evidence suggests new high-Dk silicone lenses are safe for up to 30 days of continuous wear.
- Successful continuous vision is now achievable with appropriate patient and practitioner guidance.
Conclusions:
- High-Dk silicone contact lenses represent a safe modality for up to 30-day extended wear.
- Comprehensive education for both practitioners and patients on complication recognition, management, and proper eye care is essential.
- Continuous vision with contact lenses can be safely offered, provided risks are understood and managed.
