  1. The Use of Therapeutic Contact Lenses in Pediatric Patients with Low Vision Kelly E. Lusk, Ph.D. Terry Schwartz, M.D. Cincinnati Children’s Vision Rehabilitation Program (CCVRP)

  2. Points of contact An overview of therapeutic contact lenses? Literature review Contact lens use in children Therapeutic CL use in persons with low vision Therapeutic CL use in children with low vision Discussion Contact lenses with other low vision rehab options Future directions with the pediatric population

  3. What is low vision? • A person with low vision is “a person who has measurable vision but has difficulty accomplishing or cannot accomplish visual tasks, even with prescribed corrective lenses, but can enhance his or her ability to accomplish these tasks with the use of compensatory visual strategies, low vision devices, and environmental modifications” (Corn & Lusk, 2010, p. 4-5). • Low vision devices include optical, non-optical, and electronic devices.

  4. What are therapeutic contact lenses? • A therapeutic CL is a lens that can be prescribed to some patients with low vision to further enhance visual functioning

  5. Characteristics of Therapeutic Contact Lenses • Can be hard or soft lenses • May have a prescription for a refractive error • May be clear, tinted, or opaque

  6. Why are therapeutic CLs prescribed? • Light control • Cosmetic purposes • Pathologies (e.g., keratoconus) • Patients with high refractive error • As a part of a more complex lens prescription • Therapeutic contact lenses in conjunction with other low vision rehabilitation options, such as near and distance magnification.

  7. Literature Review and Discussion Contact lens use in children Therapeutic CL use in persons with low vision Therapeutic CL use in children with low vision Relative lack of studies specifically on pediatric population Relative lack of studies looking at additional low vision rehab options/interdisciplinary models Why are these important? Where do we go from here?

  8. Future Directions • Large scale study (or studies) of children with low vision • Light-controlling contact lenses with and possibly without further vision rehabilitation options • Albinism, Achromatopsia, Aniridia, Cone Dystrophies • Age to prescribe (evaluations and follow-up) • Improvement in functional outcomes (visual performance, comfort, social acceptance, ECC areas, etc.) • Longitudinal data to support findings, continued use
