Objective:
To investigate the transmission of red and violet wavelengths through ocular structures and their implications for light-based therapies in myopia control.
Key Findings:
- Red light demonstrated greater transmission than violet light across anterior and posterior ocular structures.
- Corneal, lenticular, and retinal transmission were significantly lower for violet LEDs compared to red sources.
- The lens was identified as a key barrier to shorter wavelengths, with violet light strongly attenuated before reaching the retina.
- Less than 1% of incident light reached the sclera across all light sources examined.
- Red LEDs achieved transmission levels comparable to red lasers, suggesting a safer alternative.
Interpretation:
Limitations:
- The study used porcine eyes, which may not fully replicate human ocular responses.
- The findings may not account for variations in individual patient anatomy and light exposure conditions.
