Clinical Report: Impression-Based Scleral Lens Use

Background

Impression-based scleral lenses are beneficial for patients with complex ocular conditions where standard lenses fail to provide adequate stability and comfort.

Data Highlights

No numerical data or trial data provided in the source material.

Key Findings

• The patient had a history of severe ocular surface symptoms due to Sjögren’s syndrome and advanced glaucoma.
• Initial fitting with a standard scleral lens improved visual acuity but caused significant edge awareness.
• Switching to an ovate impression-based lens design enhanced usability for the patient.
• After four months of wear, the patient experienced significant improvement in ocular surface health and quality of life.
• Final visual acuity was 20/20 OD and 20/25 OS at distance, with improved corneal staining.

Clinical Implications

Clinicians should consider impression-based designs for patients with complex ocular conditions.

Conclusion

Impression-based scleral lenses can provide ocular surface protection and accommodate individual handling needs.
