Clinical Scorecard: Maintaining Corneal Health During Scleral Lens Wear
At a Glance
| Category | Detail |
|---|---|
| Condition | Corneal health during scleral lens wear |
| Key Mechanisms | Oxygen delivery and tear exchange |
| Target Population | Individuals wearing scleral lenses, particularly those with endothelial abnormalities |
| Care Setting | Optometry and ophthalmology clinics |
Key Highlights
- Fenestrations and back surface channels enhance corneal oxygen transmission.
- Channels aid in carbon dioxide removal and reduce corneal edema.
- Fenestrated lenses can help manage complications from corneal hypoxia.
- Bubble movement is crucial to prevent localized corneal desiccation.
- Efficacy of fenestrations and channels is mixed according to recent studies.
Guideline-Based Recommendations
Diagnosis
- Evaluate corneal health and endothelial status before scleral lens fitting.
Management
- Consider fenestrated scleral lenses for patients at risk of corneal hypoxia.
Monitoring & Follow-up
- Regularly assess corneal health and lens fit during follow-up visits.
Risks
- Complications may arise from corneal hypoxia, especially in patients with endothelial abnormalities.
Patient & Prescribing Data
Patients requiring scleral lenses for vision correction or ocular surface disease.
Fenestrated designs may alleviate handling difficulties and improve comfort.
Clinical Best Practices
- Incorporate channels in lens design to enhance tear exchange.
- Polish sharp edges of channels post-manufacturing to prevent discomfort.
- Educate patients on the importance of lens care and monitoring corneal health.
