Pellucid Marginal Degeneration (PMD) Challenges Overcome with Onefit Scleral Contact Lenses

Year: 2025

Type: article

Abstract: Pellucid marginal degeneration (PMD) is a bilateral, peripheral corneal ectasia characterized by inferior corneal thinning and subsequent irregular astigmatism, often leading to poor visual outcomes with glasses or traditional contact lenses. This case report presents a 45-year-old female previously misdiagnosed with keratoconus and advised to consider corneal transplantation due to poor visual acuity and intolerance to earlier contact lens fittings. Comprehensive examination revealed PMD, and the patient was successfully fitted with Onefit scleral contact lenses. The lenses provided significant improvement in both vision and comfort, enhancing her quality of life and eliminating the need for surgical intervention. This case highlights the importance of accurate diagnosis and the efficacy of scleral lenses, particularly the Onefit design, in managing moderate to advanced PMD cases.
