Clinical Scorecard: GP Insights: Corneal Sensitivity and GP Lenses

At a Glance

Key Highlights

• Corneal sensitivity affects GP lens comfort and wear tolerance.
• Topical anesthesia can improve initial GP lens fitting comfort.
• Corneal sensitivity decreases with GP lens wear but recovers after cessation.
• CXL may temporarily reduce corneal sensitivity, improving GP lens tolerance.
• Neurologic sensory adaptation may enhance comfort over time.

Guideline-Based Recommendations

Diagnosis

• Assess corneal sensitivity and overall lens fit in keratoconus patients.

Management

• Consider corneal collagen cross-linking for progressive keratoconus.
• Utilize topical anesthesia during initial GP lens fitting.

Monitoring & Follow-up

• Monitor corneal sensitivity and lens comfort over time.

Risks

• Long-term use of topical anesthesia can be toxic to corneal epithelium.

Patient & Prescribing Data

Young patients with keratoconus.

Reattempt GP lens fitting post-CXL after monitoring corneal sensitivity.

Clinical Best Practices

• Educate patients on the potential for improved comfort over time with GP lenses.
• Evaluate and address anxiety and pain tolerance during lens fitting.
