To evaluate the effectiveness of orthokeratology lenses in alleviating dry eye symptoms in a pediatric patient with progressive myopia.
Approach:
Case Description: A 10-year-old patient with progressive myopia and dry eye symptoms was assessed for orthokeratology lenses.
Lens Design and Material: A reverse-geometry ortho-k lens design was selected, utilizing high-Dk rigid GP materials to enhance corneal oxygenation and minimize irritation.
Follow-Up: The patient reported symptom relief and improved visual acuity after wearing the lenses overnight.
Key Findings:
Ortho-k lenses can retain a tear reservoir that may reduce dry eye symptoms (van Setten, 2024).
High-Dk materials are essential for maintaining corneal health during overnight wear (Lum and Swarbrick, 2011).
The patient achieved 20/20 vision in both eyes after treatment.
Limitations:
The study is based on a single case report, limiting generalizability.
Preexisting dry eye conditions may complicate treatment outcomes.
Conclusion:
The use of high-Dk materials in orthokeratology is critical for minimizing corneal swelling and maintaining ocular surface hydration.
