Summary
Extended wear contact lenses offer convenience but pose risks. This review details physiological and mechanical complications of both hydrogel and rigid gas-permeable lenses, outlining causes, symptoms, and treatments.
Area of Science:
- Ophthalmology
- Corneal Science
- Contact Lens Technology
Background:
- Extended wear contact lenses provide convenience and comfort for many wearers.
- However, both hydrogel and rigid gas-permeable (RGP) lenses carry risks of physiological complications.
- Complications are more frequently reported with hydrogel extended wear lenses.
Purpose of the Study:
- To review the physiological and mechanical complications associated with extended wear contact lenses.
- To cover both soft (hydrogel) and rigid gas-permeable lens materials.
- To discuss the etiology, clinical presentation, and management of these complications.
Main Methods:
- Literature review of studies on extended wear contact lens complications.
- Analysis of reported physiological and mechanical issues.
- Synthesis of information on causes, symptoms, and treatment strategies.
Main Results:
- Extended wear of hydrogel lenses is associated with a higher incidence of physiological complications compared to RGP lenses.
- Both lens types can lead to various physiological issues, including infections and hypoxia.
- Mechanical complications can also occur with both soft and rigid lens materials.
Conclusions:
- Extended wear contact lenses, while convenient, necessitate careful consideration of potential complications.
- Understanding the etiology, presentation, and management of these issues is crucial for eye health.
- Further research may focus on developing safer extended wear materials and protocols.
