Using Orthokeratology Lenses to Aid Dry Eye Symptoms

Clinical Report: Using Orthokeratology Lenses to Aid Dry Eye Symptoms

Background

Orthokeratology lenses are designed to reshape the cornea and are increasingly recognized for their role in managing pediatric myopia. Understanding the interaction between ortho-k lenses and dry eye conditions is essential for optimizing treatment outcomes.

Data Highlights

The case study involved a 10-year-old patient with progressive myopia and dry eye symptoms, who achieved 20/20 visual acuity after wearing high-Dk ortho-k lenses.

Key Findings

Ortho-k lenses can retain a thin tear reservoir that may help reduce dry eye symptoms.
High-Dk rigid GP materials are recommended for overnight ortho-k wear to enhance corneal oxygenation.
The selected lens parameters were tailored to the patient's corneal topography and refractive error.
The patient reported wearing the lenses for 8 to 9 hours nightly with symptom resolution.
Reduced-oxygen delivery can disrupt corneal metabolism and exacerbate epithelial compromise.

Clinical Implications

The use of high-Dk materials in ortho-k lenses is essential for maintaining corneal health during overnight wear.

Conclusion

Ensuring adequate oxygen transmissibility is crucial for long-term corneal health.
