Problem Statement

Target Audience: Optometrists, ophthalmologists, and eye care professionals, especially in resource-limited settings.

Clinical Use Case: SPARC offers a portable, affordable peripheral refraction assessment by integrating with standard retinoscopes, enabling accurate peripheral refraction measurements essential for effective myopia management.

​

Quantitative Impact & Deployment Details

• Accuracy: SPARC's measurements at 22° nasal and temporal eccentricities showed mean differences of +0.11 D and +0.13 D, respectively, compared to open-field autorefractors, indicating strong agreement.
   

• Clinical Adoption: In 2024, SPARC was deployed across LVPEI’s network, enhancing peripheral refraction assessments in both pediatric and elderly populations.

 

Features

• Integration with Standard Retinoscopes: SPARC attaches to a conventional trial frame, facilitating peripheral refraction measurements without additional bulky equipment

• Portability: Its compact design allows for easy use in various clinical settings, including outreach programs and small clinics.

• User-Friendly: Designed for ease of use, SPARC enables practitioners to perform assessments with minimal training.
