Clinical Scorecard: Profilometry-Guided Scleral Lens Design for Keratoconus
At a Glance
| Category | Detail |
|---|
| Condition | Keratoconus |
| Key Mechanisms | Scleral lenses designed to match the ocular surface shape to prevent complications. |
| Target Population | Patients with keratoconus and corneal transplants. |
| Care Setting | Specialty contact lens fitting. |
Key Highlights
- Poorly designed scleral lenses can cause conjunctival compression and granulomatous lesions.
- Profilometry-guided freeform lenses significantly improved patient comfort and vision.
- Sequential lens modifications were necessary as the ocular surface changed.
Guideline-Based Recommendations
Diagnosis
- Evaluate ocular surface shape and existing conditions before scleral lens fitting.
Management
- Use profilometry-guided scleral lenses to match the individual shape of the sclera.
Monitoring & Follow-up
- Regularly assess lens fit and ocular surface changes to adjust lens design.
Risks
- Improperly fitted lenses can lead to chronic inflammation and vision impairment.
Patient & Prescribing Data
Adults with keratoconus and previous corneal surgery.
Customized lens fitting can resolve complications and improve visual acuity.
Clinical Best Practices
- Perform scleral profilometry to guide lens design.
- Monitor for changes in ocular surface and adjust lenses accordingly.
- Educate patients on the importance of proper lens fitting.
