Summary
Therapeutic soft contact lenses protect the eye and aid healing. Advances in high-oxygen (high-Dk) lenses offer enhanced options for eye care professionals to manage patient treatment effectively.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- Therapeutic soft contact lenses, first approved in the 1970s, have evolved significantly in materials and parameters.
- Current options allow for corneal surface protection and modulation of the healing process.
Purpose of the Study:
- To summarize available therapeutic contact lenses.
- To outline conditions treatable with therapeutic contact lenses.
- To guide the optimal selection of therapeutic contact lenses for individual patients.
Main Methods:
- Review of available therapeutic contact lens materials and parameters.
- Discussion of conditions amenable to therapeutic contact lens treatment.
- Guidance on patient communication and off-label use considerations.
- Analysis of new high-Dk lens technology.
Main Results:
- A wide array of therapeutic contact lenses are available, with ongoing material and parameter evolution.
- Many cosmetic soft contact lenses are used off-label for therapeutic purposes.
- New high-Dk lenses offer potential improvements in reducing vascularization and infection risks.
Conclusions:
- Optimal selection of therapeutic contact lenses requires consideration of specific patient healing objectives.
- Advances in contact lens technology enhance the utility of traditional lenses and permit more selective application.
- Patient communication regarding therapy goals, risks, and off-label use is crucial.
